BADI - ADDRESS_UPDATE and BUPA_ADDR_UPDATE

Hi Everyone,

I am trying to update Phone Numbers (Table ADR2) in the background when user creates new address using FPP2/BUG2 transaction.

I am looking for an BADI where I can read the Address from Memory and after populating the Phone Numbers, update the Memory again, so that SAP can update the numbers from memory.

I was trying to implement BADI - ADDRESS_UPDATE and BUPA_ADDR_UPDATE. I am able to read data using FM ISU_PARTNER_MEMORY_GET / BUA_BUPA_MEMORY_ADDRESS_GET, but not able to modify memory using FM ISU_PARTNER_MEMORY_SET.

Can anybody tell me any FM/BAPUI which can update the memory back so that phone numbers get updated properly or is this the right place to modify the memory.

Thanks,

Durgesh.
