ISU debitor is losing name when address is added to business partner in CRM

Hi,

In CRM, we are adding a new standard address to a businesspartner via the FM BUPA_ADDRESS_ADD. This works, and we get no error messages.

However in the replication log, we are getting the message that the field ADDR1_DATA-NAME1 is missing. After having done some debug work on the idocs, we found out that somehow the fact that we change the address in CRM is deleting the name of the equivalent debitor in ISU.

Would someone have an idea why this is happening and of how we could solve it?

Kind regards,

Thomas
