CRM --> R/3 Customer Replication with view "Company code data"

Customer is getting replicated into R/3.

Additionally I need to create "Company code data"

along with predefined (hardcoded) company code.

I have written on R/3 side & called from CRM 4.0 under Middleware --> Customer Specific flow under BDoc Type "BUPA_MAIN".

Transaction "SMW01" shows error "Update could not be completed".

At R/3 side, I called statement "CALL TRANSACTION "

in FM with Update task. And after that

called "BAPI_TRANSACTION_COMMIT", then "SMW01"

shows error that

"Validation error : Customer Already exists"

Is there any way to call bdc after BDoc data committed?
