Business partner - customer creation via BUPA_INBOUND_MAIN_SAVE and DEBMAS

[unes-1993]

Hello folks,

I am working on an interface that will enable customer business partner creation from an external system to SAP S4, and it seems that I will have to use BUPA_INBOUND_MAIN_SAVE iDOC type to create the BP, along with DEBMAS for customer role extension.

But I still don't know how to link both of them ? how the DEBMAS will make the connection with my BP already created through BUPA_INBOUND_MAIN_SAVE ?

Thanks in advance for your help

Removed the SAP S/4HANA Cloud tag as this query seems to relate to S/4HANA On-Prem

Hello,

If your S/4HANA solution isn't too old, DEBMAS already follows the BP first approach. This means, it takes care of creating the BP along with the customer role(when you send data in the right manner). BUPA_INBOUND_MAIN_SAVE module is internally triggered for the BP creation.

Hello, thanks for your answer ! But there are some required fields that don't exist in DEBMAS but doin BUPA like (Identifiers, tax category and industry), therefore what is the approach ?

[shwetha_hs]

Hello,

You are right. Not all fields are available in the IDOC structure. And this is the reason, SAP recommends to use web services BusinessPartnerSUITEBulkReplicate* for replication than IDOCs.

We can't use webservice unfortunately, that's why I am looking for a solution to do it through idocs

Please be careful before using DEBMAS about below restrictions. I would suggest to use API or custom interface wrapper and call BAPIs to post/create BP+Customer from external source, for the mere fact --CVI is quite robust in the direction of BP to Customer and BP to Vendor, but not so mature in the opposite direction.

IDOCs integration in S/4 for creation of Customer/Supplier with same number as BP (Customizing configured as BP Internal numbering and Customer/Supplier External numbering with same number) will not be supported.

Merging related Customer and Vendor into a single BP is a complex and constrained scenario (e.g. SAP Note 2617002 - Legal Entity Check).

Note: If you decide to setup CVI config in opposite direction- then after migration/conversion of all your C&V,you have to reveres the configuration again- since going forward S/4 will have BP as first entity for any new C&V.That way two step journey to PROD for transports and change management.

Hello, thanks for your answer ! The only problem with APIs is that I can't modify sales and company code data, but only the general one ! My interface is supposed to carry out creation along with modification.

We have done in multiple S/4 implementations and using proper technique you can create/change/delete all views of BP.
