Redefine Standard OData Service with new Sandard Property

[former_member641127]

Hi,

I try to add a standard property in a standard OData service.

I use the SEGW Transaction.
The external service name is "FAC_FINANCIAL_DOCUMENT_SRV_01" >> used in FIORI application "Manage Journal Entries (F0717)".
The standard project in SEGW is "FAC_FINANCIAL_DOCUMENT".

I try to add the property "EMPFB" (Payee/Payer).
This property exist in the ABAP Structure "FAC_S_ACCDOC_GL_ITM_ODATA_DSP" used in the entity type "Item" in the project "FAC_FINANCIAL_DOCUMENT".
She exist in the structure but not in the Properties of the Item's entities.

I tried to :

• Redefine and select just the Item entity within a new project : The new property was never available on the main service and the FIORI application was down.
• Redefine and select all the entities within a new project, with and without "Overwrite Base/Extended Service", same result. (Error message in Gateway Error Log "Association Set HeaderDocumentViews not defined in Metadata". but the association exist ...
• Change the standard project, but I can't (It seemed to easy ...)
• Copy the standard project, add my new property and finaly change the service with the transaction /IWBEP/REG_SERVICE to use my new Data Model and Class, but I face to an error when I used the FIORI application "Value-List FAC_FINANCIAL_DOCUMENT_SRV_01.Header/AccountingDoc not found in Metadata".

My request seemed to be easy, but finally ... no
Do you have an idea ?

Thanks and Regards,
Youri

Hello.

If somebody else still faces this issue then use Implicit Enhancement in MPC_EXT class to add required field from structure for display in Fiori. Then it will work. For me it didn't work either with redefining standard oData service.
