Hi Experts,

I am trying to execute the example to create sales order with Line Items using Deep Insert method.

Whenever I am trying to get the IO_EXPAND parameter it is coming as N means it is not able to resolve the structure passed.

I have already created Associations and Navigations as mentioned in How to guide.

Please guide me to proceed.

Thanks,

In this blog I will explain Creating Gateway service with all CRUD operations  Before starting, I am expecting that you have basic idea of gateway service and gateway service builder i.e SEGW

1. Create service in Gateway system with all the CRUD operations.(Create Read Update Delete)

Create project in SEGW (Gateway Service Builder).

Our Project looks as below.

Now we need to build our Data model, for that first Create the Entity type by importing an RFC Interface.

Give the Entity type name, RFC destination and name of the RFC to be imported and click on next

Select the required properties for the entity type.

Set key property for the entity type, here we will make Material as key then click on Finish.

Our Entity type MATR and its properties look as below.

Create Entity set with necessary entity type.

Give appropriate Entity set name and select the necessary Entity type then click on continue.

Our Project looks as below.

After creating Entity set Service implementation also created with empty CRUD operations which needed to be implemented by mapping with RFC/BOR interface.

Now we need save our changes within a request.

Now click on generate button to generate runtime artifacts.

Data provider and Model provider classes will be created. Click on ok.

Save the changes.

Runtime artifacts are generated and looks as below.

Now we need to implement all the CRUD operations in Service implementation.

Create

Read/Query

Update

Delete

CREATE: This is to create a new entry. Right click on create and choose Map to data source option.

Give the RFC destination name and select required RFC then click on ok.

Now click on propose mapping, the system will do mapping automatically or else we can do it manually for required fields. Here no need to map all the properties of the entity type; we will map only the required properties. We will do the mapping by drag drop from Function Module onto data source parameter of the Service operation.

Here all the required fields will have input mapping as below.

Here in our case we need to pass constant values for BASE_UOM, MATL_GROUP and BASIC_VIEW, we will do that as follows. First append the rows and maintain values under constant value tab.

Once mapping is done save your changes. Now we will implement DELETE operation.

DELETE: Right click on Delete and choose Map to data source option.

Give the RFC destination name and select required RFC then click on ok. Here we are mapping with BAPI_MATERIAL_SAVEDATA.

Do the required mapping as follows. Here we are passing Material, DelFlag, MatlGroup fields so do the mapping accordingly.

READ: Right click on Read and choose Map to data source option.

Give the required RFC and do the mapping as below. Here we are mapping Material, MatlDesc, IndSector, MatlType, MatlGroup,BaseUom fields. Except Material all are having output mapping.

Note: In READ operation all key fields should have input mapping, here in our example Material is key.

QUERY: Right click on Query and choose Map to data source option.

Note: In Query operation all key fields should have output mapping. Here we can also map ranges directly to pass range value for selection.

Give the required RFC and do the mapping as below. Here we are mapping with BAPI_MATERIAL_GETLIST

Here we will map MatlDesc property with appropriate Function field and our key property Material with range table, for that just drag drop that filed on to the data source field. Click on ok in the below screen.

Our mapping looks like below.

Here for display purpose we will again add Material property since all key fields should have output mapping in Query operation.

For this click on create button and choose the Material property and do the necessary mapping as shown below.

UPDATE: Right click on Update and choose Map to data source option.

Give the required RFC, Here we are mapping with BAPI_MATERIAL_SAVEDATA.Do the required mapping as follows. Here we are going to update MatlGroup Field.

After completing all the implementations save the changes and check for syntax errors.

Now again click on Generate button to regenerate the runtime artifacts.

Check the success messages.

With this we have successfully created a gateway service with implementing all CRUD operations.

In the next part Detailed step by step procedure for Creating Gateway Service with all the CRUD Operations and testing them in Service Explorer Part2

we will maintain our service and test it in Service Explorer

In the first part Detailed step by step procedure for Creating Gateway Service with all the CRUD Operations and testing them in Service Explorer Part1

I discussed the the below topic.

1.Create service in Gateway system with all the CRUD operations.(Create Read Update Delete).

Before starting, I am expecting that you are able to create gateway service or you have gone through my previous blog.In this blog i will discuss about maintaining our service and testing it in ServiceExplorer.

Our Service Name: ZBPS_MATR_DEMO_SRV.

Now we need to Activate and Maintain our service, we will do that in transaction /IWFND/MAINT_SERVICE.

     a. First we need to locate and add our service. Click on add service button.

Enter system alias and press enter. From the displayed list locate our service and click o it.

Save it in a package and click on Ok.

Select the request and click on Ok. Again click on ok. Come back and click on our service.

b. Now we need to add System alias to our service, i.e. systems with which we are going to interact.

Click on Create System alias button and enter the required system details and save the changes and come back.

Save the changes in the request.

Now we can see our system alias details.

Now we will explore our service for that click on Explore service button.

Click on Execute to get Service Document .

Service Document:  Describes the location and capabilities of one or more Collections.

Here we can check our Entity set name and we will get our Service URI.

Here our URI: http://<hostname>:<port>/sap/opu/odata/sap/ZBPS_MATR_DEMO_SRV/

Now come back and now choose Get Service Metadata option as shown below and click on execute to get the service mete data.

Now we will get our service Meta data.

Service Metadata Document (Metadata Document): Describes the data model (i.e. structure and organization of all the resources) exposed as HTTP endpoints by an OData service.

Note the URI of our service and we will use it further.

URI: http://<hostname>:<port>/sap/opu/odata/sap/ZBPS_MATR_DEMO_SRV/$metadata

Testing Our Service.

Now we will test our service in Gateway Client transaction for that is /IWFND/GW_CLIENT.

Paste our URI in Request URI field and click on Get HTTP Method.

Check the Service Meta data.

Now we will test all the CRUD operations.

READ:

Here in URI we can pass values for key fields only.

In our example we are trying to READ Material ‘000000000000000023’ and we will do that in Gateway client.

URI: http:// <hostname>:<port>/sap/opu/odata/sap/ZBPS_MATR_DEMO_SRV/matrset('000000000000000023')

Paste this URI against Request URI field in Gateway client and select HTTP Method GET and click on execute.

Output:

QUERY:

Query is to get multiple entries and here we can pass ranges for selection.

In our example we will try to fetch Materials within the range ‘000000000000000023’ to ‘000000000000000038’.

URI:

http:// <hostname>:<port>/sap/opu/odata/sap/ZBPS_MATR_DEMO_SRV/matrset?$filter=Material ge '000000000000000023' and Material le '000000000000000053'

Paste this URI @ Request URI in Gateway client and select HTTP Method GET and click on execute.

Output: We will get three materials in our output   

CREATE:

Now we will try to create Material ‘000000000000000016’. For this first we will READ an existing material and using that XML we will CREATE desired material.

First try to READ Material ‘000000000000000023’ by using the URI same as in our READ operation in Gateway client.

Now click on Use as request button as below.

We will get same XML in HTTP Request Body. Make require changes in that for Material creation. Here we need to select HTTP Method POST for CREATE operation and we need to change URI as below.

URI:

http:// <hostname>:<port>/sap/opu/odata/sap/ZBPS_MATR_DEMO_SRV/matrset

OUTPUT:

UPDATE: Now we will try to UPDATE the Material just we have created through CREATE operation.

Do the same steps as in create operation, first read the Material ‘000000000000000016’ through READ operation and by using that xml as a Request we will try to UPDATE Material Group of that Material.

URI: http:// <hostname>:<port>/sap/opu/odata/sap/ZBPS_MATR_DEMO_SRV/matrset('000000000000000016')

Here MatlGroup is 00108, we will update that to 00107 and we will verify it through READ operation.

Click on Use as Request and make the necessary changes to the XML as below and select the HTTP Method PUT for Updating and click on execute.

Xml:

<?xml version="1.0" encoding="utf-8"?>
<entry xml:base="http://<hostname>:<port>/sap/opu/odata/sap/ZBPS_MATR_DEMO_SRV/" xmlns="http://www.w3.org/2005/Atom" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices">
<content type="application/xml">
<m:properties>
<d:BaseUom>EA</d:BaseUom>
<d:MatlGroup>00107</d:MatlGroup>
<d:BasicView>X</d:BasicView>
<d:MatlType>ROH</d:MatlType>
<d:IndSector>1</d:IndSector>
<d:Material>000000000000000016</d:Material>
<d:MatlDesc>Test material gateway</d:MatlDesc>
<d:LanguIso>EN</d:LanguIso>
<d:Langu>E</d:Langu>
</m:properties>
</content>
</entry>

OUTPUT:

Now we will check that whether that Material is updated or not by using READ operation. Select the HTTP Method GET and check the output.

DELETE:

Now we will try to DELETE the Material which we have created, for this we use HTTP method DELETE.

Here to delete the Material we will just set the Delete Flag to ‘X’. First we will read that material and using that xml as a request we will process Delete operation. Here we will select HTTP method DELETE and execute it after modifying xml.

XML:

<?xml version="1.0" encoding="utf-8"?>
<entry xml:base="http://<hostname>:<port>/sap/opu/odata/sap/ZBPS_MATR_DEMO_SRV/" xmlns="http://www.w3.org/2005/Atom" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices">
<content type="application/xml">
<m:properties>
<d:MatlGroup>00107</d:MatlGroup>
<d:Material>000000000000000019</d:Material>
<d:DelFlag>X</d:DelFlag>
</m:properties>
</content>
</entry>

OUTPUT:

With this we have completed all the CRUD operations.

Dear Experts,

As of now we have been able to send workflow decision task(no forms is attached to this) from SAP Backend system to the Gateway system and then sending them to the Lotus Notes Server in ODATA format and user is able to approve/reject the worktiem from Lotus Notes Email.

We have developed HCM Process and Forms using FPM(Floor Plan Manager) for several HR Process like Employee Transfer, Contract change , compensation change etc. and the requirement is to transfer the whole form(attached to the workflow task) to the Gateway system and eventually sending them to Lotus notes Server so that the user can approve/reject the request from Lotus Notes application like Lotus Notes Email.

Can anyone please let me know whether is it possible at all and if it is possible then how to do this or what are the additional steps needs to be followed for this.

Your response is highly appreciated....Thanks in advance!!!!!

Hi,

As part of a training exercise, I need to first...
1) go to T-code "SEGW",
2) create a project/or use an existing one and
3) import an OData file

4) create an Android App

as instructed in the course titled course - Introduction to Mobile Solution Development for the Enterprise using the https://sapes1.sapdevcenter.com/webgui link.

But I  neither can CREATE nor VIEW an existing project in T-code "SEGW" (i.e. SAP NetWeaver Gateway Service Builder) in that environment. The error that I receive says "You are not authorized to create project".

Just wanted to know if anyone else has faced a similar issue earlier and what was the workaround used to resolve it.

NOTE: I have installed all the necessary plug-ins in Eclipse as mentioned in the below document:
http://scn.sap.com/docs/DOC-45809

Welcome to sign up for the SAP Netweaver Gateway Service Consumption System. If you feel comfortable with handling an SAP ERP System feel free to jump immediately to the sign up below. We do however suggest that before doing so you take the time to read this document as it will not only give you the information on how to connect but also other valuable information you might need when using the system.

Where do I sign up?

To get started follow this link to the sign up form. When you sign up the form will take your SCN data as user data. The form also asks you to agree to the EULA. Once you have done that an email will be send to the email address that SCN has on file for your user with your logon information. Please make sure that the email address displayed is a valid email address for you if it is not please update your email address in your SCN profile before registering to the system.

How do I connect to the system?

Minutes after you registered to the system you should receive an email with your username and password. Once you have that the fastest way to change your initial password is by using the WebGUI. The WebGui for the system is located at https://sapes1.sapdevcenter.com/webgui. The WebGui is also the simplest way to connect to the system and navigate around in it. It is best to use Microsoft Internet Explorer for WebGui although Firefox and Safari should work fine too. We do however advice against using Google Chrome as we have seen things not working.

If you happen to have SAP Gui Windows or Java version you do however also have the option of creating a connection to the system in there. At this point we do not have an option of giving SAP Gui to you should you not have the rights to download it from SAP Service Marketplace. The connection information for SAP Gui to the system is as follows:

Application Server: lvpal259.dmzpal.sap.corp

Instance Number: 00

SystemID: ES1

SAPRouterString: /H/erpgw.sapdevcenter.com/S/3299/H/

What can I do with the System?

The main purpose of the system is to learn about consuming SAP Netweaver Gateway Services. All URL's to Gateway for this system start with

https : //sapes1.sapdevcenter.com/sap/opu..

Please have a look at the Sample Services and how to use them. The system is only for consumption of OData Services not for building new ones. If you are interested in building new services you have the option of choosing one of the other systems on the previous entry page. We will not hand out authorizations for developing any ABAP on this system.

What is on the System?

The System is an SAP ECC (Enterprise Core Components) filled with some Demo Data. You do have read and write authorizations to all modules but are restricted form accessing administrative functionality. Furthermore the system allows you to access the development tools but does not allow development itself. Debugging with viewing permissions is however possible.

If I need help.

If you have a question about Gateway feel free to post a message in the forum. If you have operational questions feel free to post them in the forum as well or send an email to devcenter@sap.com. Please also consider subscribing to the Operations Announcement Dokument where we will post information on the status of the system. In the future we are going to compile an FAQ, but for now we put the most pressing things into this document.

If I forgot my username password.

Go back to the sign-up form. The form will find you in the system and allow you to reset your user. Once your user is reset you will get an email confirming that the password has been reset.

Hi all!

Our customer has a requirement, it consists in consume a set of PI/PO services (which has a lot of redirection logic to different SAP systems) using REST / OData from SAPUI5 app.

I've seen that it's possible consume Rest throught PI/PO with this private add-on Advantco REST adapter. But I would to know if it's is possible to install Gateway Add-On in PI/PO Abap stack to consume PI/PO functions in REST / OData.

Thanks in advance,

Kind regards

Hi,

    I created a project using the segw t-code for which I need to import the Data Model by DDIC structure. I am trying to look for the BAPI CUSTOMER_GETDETAIL1 but it doesn't appear. I looked it's package details using the transaction se37 . I used that package name to search while looking for the BAPI's in segw , but it still did not appear in the list.

        I also tried searching BAPI_CUSTOMER_GETDETAIL1 and BAPICUSTOMER_GETDETAIL1 and few other combinations, but nothing worked.

        Looking forward to your suggestions now.

Ravi Chaudhary

When attempting to register and activate a service through the Service Builder the field External Service Name cannot be changed.  In various documentation I commonly see the statement:

     The External Service Name is defaulted with the Technical Service Name

Is there some requirement that these names must match or is it is possible to change this value somehow?

Hi there,

Is there an updated version of the document referenced in this link http://scn.sap.com/docs/DOC-3431?

I just want to ensure I have most current information as this document references SAP 4.6C and AD2003.

Many thanks, H.

Hi guys!

I have problems during Installation of Fiori App "My Leave Request" on NW 7.4 System.

Installation of UI component: UIHCM002 100 worked fine but during Installation of OData Component GBHCM002 600 I got the message

that the Add-on IW_BEP Release 200 is missing and I cannot proceed with the installation.

So far as I know is the Add-on IW_BEP part of the component SAP_GWFND in NW 7.4 and its not possible to install them?

Thx for your help!

BR, René.

Hi All,

    Within all the discussions about Gateway and OData sevices, I couldn't answer to a basic question I have... Hope someone here could answer it for me.

    We have a NW 701 ABAP system with the IW_BEP Addon installed. I understand that this is enough to create OData channels from ABAP.

    However, every blogs/articles goes ahead to GW_CORE as further steps to expose the OData channel as gateway services to the world. That's fine, but I'd like to know if I want to develop a UI5 application that's hosted right within the same ABAP server (using SAPUI5 runtime), then is there a way to consume these OData channels directly without the GW_CORE?

Can anyone refer me to any articles, wiki or blogs etc. that has such an information?
