Return Table in POST Function

April 27, 2015, 2:06 pm
$

Hi Gurus,

 

I'm very new to GW services and Service which I'm currently working on is to Create Invoice. I took the RFC/BOR Route and RFC FM got 2 parameters:

 

1. Input Table - Accepts both Header and Item information

2. Output Table - Returns error or success message (Got 2 columns: Message Type and Message)

 

This means 2 entity sets in GW service: one for Input and another for Output Table.

 

Through "Map to Data Source" option, mapped the Input table to RFC Parameters and generated code looks good where the input parameters are aligned with RFC FM parameters.

 

Issue is how should I get the response back from the FM as the return table is another entity set. Can you please suggest.

 

Thanks,

Karthik

Content-type      - Image/Jpeg

xcsrf-token        - XXXXXXXXXXXX==  ( Using my get service)

Same RFC Destination for Dev and Quality?

Hi Experts,

 

When we move the Gateway TRs from Quality to Dev Environment the RFC destination is carrying along with the TR.

Now the problem comes while loading the mapping in Quality. To avoid this again we have to create another RFC Destination with same name which was created in DEV. Its violating the Naming Standards.

 

For Example

 

Dev_ABCCLNT500 (Dev Environment )  -----> Dev_ABCCLNT500(Quality Environment)

 

Could you please revert me if there any options to avoid this.

Problem with GW Runtime

Hello,

 

I want to implement a simple GW-Service (a list of flights).

I have imported a structure from DDIC and want to implement the corresponding method (get_entity_set). As long as I do not write something to the result-table (et_flights), everything is ok (the method is used, I tried this using exceptions). Whenever I insert a flight in the table, the runntime error UC_OBJECTS_NOT_CHAR (exit CONVERSION_EXIT_SDURA_OUTPUT) appears. Is this a problem of my implementation or of the configuration of the system (ERP, on NW 740  SR1, SP Stack 4).

 

With kind regards,

Thomas Bayer

Issues creating Odata service on Solman 7.1

Hello Folks,

 

I have configured SAP NW gateway on Solution Manager 7.1 SP12. I have made a Z development in Solution manager which I need to convert into O data and consume it using UI5 application.

 

Being quite novice to the field, I have some doubts. I am following SAP standard "How to Develop a Gateway Service using Code based Implementation" guide. I am facing some issues at "Service Implementation for GET_ENTITYSET" step. According to the document, I need to add the below code to method get entity set.

 

********************************************************************************

 

CALL FUNCTION 'BAPI_EPM_PRODUCT_GET_LIST'

TABLES

HEADERDATA = et_entityset

.

endmethod.

 

********************************************************************************

 

However, after adding this code, I am getting the below error.

 

 

Error: Call of the function BAPI_EPM_PRODUCT_GET_LIST failed; a field should be assigned to the parameter HEADERDATA - the types match,

 

The detail screenshots have been attached with the message.

Can any one please let me know where am I going wrong?

 

Thanks and Regards,

Benjamin

Issue with Gateway Attachments

Dear GW Experts,

We are facing an issue with attachments in Gateway. We are using SAP DMS for our attachments. since gateway sends the attachment in Binary format and we are not able to find any BAPI/FM to create DMS attachments as none of them accepts binary format. We tried to use BAPI_DOCUMENT_CREATE2 but it needs the path as import parameter and but since the document get attached in background in the create stream method in the DPC class we cannot use a path in front end like (c:\temp\test.txt), so please advice how to achieve this.

How the performance oData comparing RFC's

May 10, 2015, 12:15 am

Hello Experts,

 

I am new to SAP Mobile technologies.

 

My client already using web based .net application and there are many RFC Function Modules already exist and the same RFC Function Module called from .net application.

 

Ex: To fetch open Sales order and changing the status from .net. Actually inside R/3 RFC Function Module called the standard BAPI and returning result to .net web application.

 

Note : Now our client is upgraded into ECC 6.0 from R/3 4.7.

 

I have come across from scn forum the oData can be used in any programming language(ASP/.Net/PHP/Phython/Java and etc.)

 

Can we migrate all RFC's to oData service using netweaver gateway programming. Below are my basic questions.

 

1. What is the advantage using oData comparing RFC's? is there any merits and demerits using the new oData technology? It is advise to use oData?

2. Will it support network load since many RFC's are returning around 50K records to .net.

3. My client planing to implement mobility and my basic question is what is the use of Syclo, Agentry and Fiori? is all the three can be used oData framework? My client proposed to use Syclo Agentry so the oData framework will it support? I heard the oData is the platform independent and can be connect any source.

 

Please advise me. I am waiting for your earliest response and best practice as well.

 

Regards,

A Vadamalai.

Not able to delete entity using a navigation path

Hi,

 

When I try to delete an entity I get this error in chrome dev tools:

It seems like you cannot use a parent entity in your url for a delete operation. I don't get this because in the backend, the DELETE method has the import parameter IT_NAVIGATION_PATH...

 

I can fix this by using an extra id of the super entity in the sub entity, but I prefer a cleaner solution (navigation path).

 

Can someone explain me what I'm doing wrong, and how I should do it?

 

Thanks,

The navigation information 'ErrorCaseSet_ERRORDETAILSET' is not valid

Hello,

 

I created a project in SEGW and used for my header and detail structure for each a different ABAP CDS view. I built an association from the header to the detail which has a 1..1 relationship.

 

When I test this all works ok, e.g. I get data for my both entity sets but if I navigate to my detail it doesn't work:

 

/sap/opu/odata/SAP/Z_IDOC_TOOL_SRV_03/ErrorCaseSet('0000000000000001')/ErrorDetailSet

 

Get this exception:

 

CX_SADL_CONTRACT_VIOLATION


The navigation information 'ErrorCaseSet_ERRORDETAILSET' is not valid


So I'm on WAS 7.40 SP9 and the Gateway is patched to SP12. I tried to look in OSS for this error but found nothing. Is there a good way to troubleshoot this association stuff?.


Here my config:


And the error:

 

The application log etc. doesn't really say more. Somehow it doesn't like this ErrorCaseSet_ERRORDETAILSET. This comes from here:

 

Any idea anybody?

 

Thanks
