Is it mandate to download the customizing object "AccountingGrp Business Partner" (DNL_CUST_ACGRPB) before to replicate customer master (CUSTOMER_MAIN)?
My understanding to replicate customer master is,
CRM no range is internal and ECC no range is external
Mapping the accounts groups with CRM classifications in PIDE settings in ECC.
Then we execute CUSTOMER_MAIN object in R3AS.
Is my understanding correct? Is it mandate to download account group for bp (DNL_CUST_ACGRPB) before we replicate customer master into CRM?
What is the use of this customizing object downloading into CRM?
