Initial Creation
Caution
You should always create business partners for the first time using the SAP BP transactions in SAP Media (IS-M)
, rather than the standard customer or vendor creation functions. We therefore recommend that you deactivate these functions for creating a customer or a vendor.
To do this, choose 
Tools
Administration
Administration
Transaction Code Administration
on the SAP Easy Access
screen.
The IS-M
system creates a customer for customer roles and a vendor for vendor roles in background processing for use in integration with Financial Accounting (FI)
or Sales and Distribution (SD)
. The business partner number must match the number of the customer or vendor master record. The number range intervals must be the same and you must specify external number assignment in FI
.
