Adding Standard MARA/MARC fields for CRUD operation in API_PRODUCT_SRV

[Pradpandey]

Hi Community Members, 

I am working on a requirement to extend API_PRODUCT_SRV (on-Prem) with few missing standard MARA & MARC fields (Not the Z-FIelds) listed below.

Field Name	Reference Table
RMATP_PB	MARA
PROD_SHAPE	MARA
MO_PROFILE_ID	MARA
OVERHANG_TRESH	MARA
SCM_HEUR_ID	MARC
SCM_MATURITY_DUR	MARA
SCM_SHLF_LFE_REQ_MAX	MARA
USEQU	MARC
SHFLG	MARC

I extended associated CDS entities like A_PRODUCT, A_ProductPlant etc with the respective fields from MARA & MARC and able to get the fields in Payload.

GET call works fine for these newly added fields however, CREATE & UPDATE operation is not working and these fields are not updated in the table. Also, I could not find any BADI to map these fields during create/Update. 

Really appreciate any suggestions on this issue. Thanks in advance.

For CREATE and UPDATE operations, ensure that your extended fields are correctly mapped to the underlying data model using the appropriate BAPIs or enhancement spots for the product entity. If no BADI is found, consider using an enhancement implementation in the relevant service definition to handle the mapping of the new fields.
