Hi Experts,

I have doubt related implementation of gateway, Why people suggest that don't write your code directly in DPC_EXT class. They suggest to create one helper class and then write your code in that method. I want to know the exact reason behind this.

Thanks & Regards,

Amit

HI,

I using some Standard  SAP Services for Fiori App, i want to find weather services are using

Hello everybody,

I have sucessfully installed NW 7.40 but during configuration of the NW Gateway (SAP_GWFND) I miss some role templates.

e.g.: /IWFND/RT_BOR_DEV; /IWCNT/RT_USER_WF; /IWBEP/RT_MGW_DSP

Any ideas? Thanks for ur  help.

Hi Guys,

I was trying to create deep entity, I have done with all the steps like associations and navigations and even association sets using segw, but I am able to create associations using manually like creating MPC and DPC classes externally.

But when I tried through SEGW, I am able to see metadata, but when I am using JSON object as request body, It is not recognizing Item entityset type as entity, it is simply taking as property.

Please do provide me some input on this.I have gone through blogs too.

Thanks

Hi all,

   i am developing a ui5 application to display a pdf through sap gateway, i followed this article ,however something strange happened.

   i followed the Improved and Recommended approach to display pdf section,it's ok with Firefox and gateway client, but not ok on Chrome and Safiri. on Chrome the pdf didn't generate in the Z_TEST_PDF_DISPLAY, when it  CALL FUNCTION lv_fm_name ,the ls_output_data is empty. On Firefox it has data. not sure why. any one  have ideas?  what should do with http header or cache response, i tried lots of codes, still not working.

thanks,

Billy

Hello Experts,

My current question is more like a conceptual question. SAPGateway delivers an OData service with an entity type containing the following Properties:

• ATNAM
• ATWRT
• ATWTB

The values of this entityset do never change and are as follows:

In UI5-Frontend, the data is consumed in different lists that filter the values of the property ATNAM and display accordingly the values of ATWTB just like you can see it in here: JS Bin - Collaborative JavaScript Debugging

Now the question: is it possible for this OData service to “be informed” of the selected value from any of these lists?  (assuming that UI5 can send a value).

Clarification: the service has only the get and getentityset methods redefined.  Or same question formulated differently: can the OData service save the result of a selection of a filtered list?

If someone wants to take a look at the metadata, the file can be seen in:  https://goo.gl/pAE4qz

Thank you very much for your support,

Gabriel

Hi expers,

This is Gowri shankar i am new to sap netweaver gateway services i just want to know about "What are File handling servises in Sap netweaver Gateway odata services in detail? Please understand my query and let me know.

Hi，

I‘m using OData SDK PHP to consume the odata in SAP system, I can use this get_entityset from SAP but not able to Create entity in SAP

my PHP code is like this

<?php
require_once "Z_WE_ASSCOCUSTOPENID_SRV_Entities.php";   //connect    $OData = new Z_WE_ASSCOCUSTOPENID_SRV_Entities
('http://192.168.1.138:8008/sap/opu/odata/sap/Z_WE_ASSCOCUSTOPENID_SRV/') ;
$OData->Credential = new WindowsCredential($_POST["userName"],$_POST["pwd"]);   try
{    //Create a Customer php Object    $OpenId = OpenId::CreateOpenId( "","",$_POST["Name"],$_POST["CustomerName"],$_POST["Code"]);    //inserting Customers object context tracking system    $OData->AddObject('OpenIdSet', $OpenId);   //SaveChange insert the object into data service   $Odata->SaveChanges();
}
catch(ODataServiceException $exception)
{    Echo $exception->getError();
}
?>
{    Echo $exception->getError();
}
?>

I will get the error Undefined property:z_we_asscocustopenid_srv_entities::$nextChange in E:\xx\xx\Context\ObjectContext.php on line 789 Unauthorized

but this property is the ODATA SDK PHP file I never change this

can you help me？

In main Class of java declare  two methods

1.initializeRestClient()

2.readExample()

In first method set the credentials...and in second method first calling Gateway after then  getting response then convert response body XML into OdataCollection object and then Iterate Odata entries in data collection and print property.....

But i am facing the exception that OdataCollection is getting Null value.

Hi , i have add a custom field ( checkbox ) on item contract in SRM . I have add  the field in SPRO: SRM Server--> Cross application basic settings --> Extensions and field Control ( Personalization) ---> Configure customer fields --> Define customer fields on item level

Thanks in advance, for your help

Hi Experts,

I have created a OData service for Create Sales Order with deep entity set with the help of following link OData Service with multiple entity set for Create SO: using standard BAPI in OData, but I am facing a problem during testing of service using json code as Input. I have not implemented the Query and Read operations for the same, because this "Create SO" it is based on standard BAPI - BAPI_SALESORDER_CREATEFROMDAT2. I need a json code to test my service. Please suggest.

Thanks

Hello,

My Scenario:

Multiple records update is required from the front end. This is achieved via Batch Processing. Upon processing of each record, an update message for each record should be sent back to UI5.

Requirement:

Need to send back the status message to UI for each single record.

Actual Process followed:

Lets say I have 3 records for updating, the sequence of methods called are as below:

1. Change Set BEGIN.

2. Update Entity (Called 3 times)

3. Change Set END.

In Begin method is just redefined and has no code.

In Update entity I am collecting all the individual record in an global internal table of same class.

In End method, calling an RFC to update all 3 records at a time. This RFC returns 3 messages indicating success or failure which needs to sent to UI.

Hence I thought to send these messages by concatenating into single message and send via Header response in method Change Set END as follows:

1. data:  ls_header               TYPE ihttpnvp. 
2. ls_header-name = 'my-custom-message' . 
3. ls_header-value = 'my_message'. 
4. /iwbep/if_mgw_conv_srv_runtime~set_header( ls_header ).

Problem:

I am not getting any header response with name my-custom-message.

Kindly suggest me to send the messages to UI5 with any corrections to above procedure or an alternative procedure.

Note: The header response with above method is only working from method Update Entity and I don't want to call the RFC for each single entity.

Satish D R

Dear specialists,

as my previous post is located in the wrong area (How to access request object in Model Provider Class),

I repost my question here:

I want to define the data model of my OData service dynamically depending on an URI paramter of my HTTP request. But so far I did not find any possibility to access the request object in the model provider class.

Does anybody has a hint for me?

Many thanks in advance.

Best regards,

Juergen

Hi Everyone,

I have a entity which is of complex data type.

Is it possible to get columns of itab which of type complex data type at runtime then How can we achieve this.

My logic is I will be getting entity columns from different table, for this I designed one dynamic itab and I am getting column component using Assign component statement. till here ok , but this value I have to pass a column name to the itab which has complex data type assigned .

Thanks in advance...

This blog will show you how to develop ODATA using Global Classes in CREATE_DEEP_ENTITY Method Operation with JSON Format using simple steps.

Step 1:

Create Custom Global Classes with below Structures.

Go To TransactionSE11 and create structures as displayed in the below screenshots.

Create Table Type ZPHYSINV_ITEMS_TAB.

Include the line type Structure.

Structure 1:

BAPI_PHYSINV_CREATE_ITEMS

Structure 2:

BAPI_PHYSINV_CREATE_HEAD

Structure 3:

Create Table Type ZRETURN_TAB.

Include the line type Structure ZBAPIRET.

Go to Transaction SE24 and create a global class with following parameters.

Global Class: ZCL_MOBIM_ICC

Parameters for Method: CREATE INVENTORY_DOCUMENT

After creating structures and class in SE24 with above given parameters, paste the below Code into the method CREATE INVENTORY_DOCUMENT.

Code Snippet:

method create_inventory_document.

Now you have created the Global Classes. Now let’s start developing ODATA in Net Weaver gateway Client SEGW for above Class.

Step 2: Create Project in SEGW

As I mentioned earlier we will implement the CREATE_DEEP_ENTITY for multiple postings with single request like one Header with multiple Line items.

In the example below, I will show posting with one Header with multiple Line items.

Create Entity Types, Entity Set, Association and Navigations as follows.

Create two Entity Types and Entity Sets.

Entity Type-1 - ICC_Header

Entity Type-2 - ICC_Items

Entity Set-1- ICC_HeaderSet

Entity Set-2- ICC_ItemsSet

Properties of ICC_Header

Properties of ICC_Items

Step 3:

Create Association and Navigation.

Create Associations as shown below.

Association - Assoc_ICCHeader_ICCItems

Create Navigation  as shown below.

Navigation – ICC_Items

Now generate runtime artifacts. Once generation is successful, you will get 4 classes. Two for Data provider classes and two for Model provider classes. Implement the code in Data provider class as shown below.

Double click on the Class ZCL_MOBOIM_ICC_DPC_EXT. Go to ABAP Workbench.

Start the Gateway client by calling transaction /IWFND/GW_CLIENT.

Enter the following URI to test your implementation.

Append $metatda to base service URI.

/sap/opu/odata/sap/ZMOBOIM_ICC_SRV/?$metadata

If everything works perfectly then HTTP response will be displayed as shown below with value 200.

Check service document append $format=json.

Step 4:

Implementing the CREATE_DEEP_ENTITY Method.

Right click and redefine the Create_Deep_Entity Method as shown in below Screenshot.

Now double click on CREATE_DEEP_ENTITY Method. Paste the code below.

Code Snippet:

method /iwbep/if_mgw_appl_srv_runtime~create_deep_entity.

*--Types Declaration for Inventory Cycle Document

  types: ty_t_iccitem   type standard table of zcl_zmoboim_icc_mpc=>ts_icc_items with default key.

*--Represents Inventory Cycle Document structure - header with one of more items

  types: begin of ty_s_icc.  "Deep Structure for Inventory Cycle Document

          include type zcl_zmoboim_icc_mpc=>ts_icc_header.

  types: icc_items type ty_t_iccitem,    "Name Should be as Entity Type Name

         end of ty_s_icc.

*--Data Declaration for Inventory Cycle Document

  data: ls_icc type ty_s_icc,

        ls_iccitem type zcl_zmoboim_icc_mpc=>ts_icc_items,

        ls_header  type bapi_physinv_create_head,

        it_item    type standard table of bapi_physinv_create_items,

        wa_item    type bapi_physinv_create_items,

        wa_icc_items like line of ls_icc-icc_items.

  constants: lc_iccitem   type string value 'ICC_Items'.

  constants: lc_countitem type string value 'Count_Items'.

  constants: lc_diffitem  type string value 'PostDiff_Items'.

*--Data Declaration for Return Message

  data: lv_compare_result type /iwbep/if_mgw_odata_expand=>ty_e_compare_result,

        lt_return  type zreturn_tab,

        ls_return  type zbapiret.

  case iv_entity_name.

   when 'ICC_Header'.

*--Validate whether the current request including the inline data matches

lv_compare_result = io_expand->compare_to( lc_iccitem ).

*-- Upon match, access data from IO_DATA_PROVIDER

      io_data_provider->read_entry_data( importing es_data = ls_icc ).

*--Pass the Header Data

ls_header-plant      =  ls_icc-plant.

ls_header-stge_loc   =  ls_icc-stge_loc.

ls_header-doc_date   =  ls_icc-doc_date.

ls_header-plan_date  =  ls_icc-plan_date.

      clear: ls_iccitem.

*--Pass the Item Data

      loop at ls_icc-icc_items into ls_iccitem.

move-corresponding ls_iccitem to wa_item.

        call function 'CONVERSION_EXIT_MATN1_INPUT'

          exporting

            input  = ls_iccitem-material

          importing

            output = wa_item-material.

        append wa_item to it_item.

        clear: wa_item, ls_iccitem.

      endloop.

*--Create Invertory Cycle Counting (Custom Global Class)

      call method zcl_moboim_icc=>create_inventory_document

        exporting

          im_header = ls_header

          im_item   = it_item

        importing

          ex_return = lt_return.

      if lt_return is not initial.

        loop at lt_return into ls_return .

          move-corresponding ls_return to wa_icc_items.

          modify ls_icc-icc_items from wa_icc_items index sy-tabix transporting type message.

        endloop.

      endif.

copy_data_to_ref(

      exporting

        is_data = ls_icc

      changing

        cr_data = er_deep_entity

        ).

      clear ls_icc.

   when others.

  endcase.

1. Endmethod.

Step 5: 

Create a Request Payload.

HTTP  Request in JSON Format:

HTTP Method   : POST

X-CSRF-Token : Fetch

Content-Type     : application/json

JSON  Format Payload:

{

"d":{

"Plant":"1100",

"StorageLoc":"1000",

"DocDate":"2015-07-21T00:00:00",

"PlanDate":"2015-07-21T00:00:00",

"ICC_Items":[

{

"Material":"2144",

"Batch":" ",

"StockType":" ",

"AltUnit":" "

},

{

"Material":"2145",

"Batch":" ",

"StockType":" ",

"AltUnit":" "

}

]

}

}

Step 6: 

Post the data with JSON format.

Put external break point and ensure whether the values are fetched in the structure or not.

Come out from the debugging.

Records will be created and HTTP response value 201 will be created as displayed below.

That’s all. You’re done with it!!!

I know the above steps will be useful in developing ODATA with Global Classes in Net Weaver gateway. Suggestions and comments for this post will be appreciated.

Hi Experts,

I have implemented GET_STREAM method to download the media entity. When I execute the service as /zservice/photo/$value media steam is getting downloaded.

I need to implement the GET_ENTITYSET method as well because this will be used in SMP Mobile and from mobile it will need to register the service by calling /zservice/photo. If this method is implemented its throwing "Invalid or no mapping to system data types found" error.

Please advise how to implement GET_ENTITYSET. Method doesn't need to return any results.

Regards,

Murthy

Hi,

I have created a function import , its for calling an API ,and there is no returning parameter.

But I am not able to select the return type kind against the Function import as No return.

While trying to generate I am getting an error ' No return is currently not supported by the runtime'.

Regards,
Vivek.
