DTR Failure in TM due to Business partner internal ID does not exist error

hi Folks,

For the SubCon STO scenario a vendor is assigned with a customer ( & vice versa) in the ECC system. The PO's created for this customer (which has the partner function LF for the vendor) the XML message fails in TM system, with a message "Business partner internal ID 0006400000 does not exist".

The business partner for 0006400000 is available in the TM system, it lacks one identification number (CRM002) when compared to the rest of the customers.

As described in the link given below the business functions LOG_SCM_CUSTVEND_INT & SCM_SCMB_TM_FND1 are activated in the system. I was expecting that when the BP was created the vendor also has the id CRM002 with the customer id in there. For some reason this is not happening & so the message fails.

Integration of Customer and Vendor Data into Business Partner - Integration of SCM Basis Master Data - SAP Library

Could you please throw some light on this issue. Any leads will be appreciated.

Just to let you know we are using TM 9.1 SP02 & SAP ECC 6.0

Regards,
