You may be wondering why. A simple example will help you understand this better.
KL-User-A wants to issue an invoice to Customer A, but Customer A is not created in the database yet, so KL-User-A create a new debtor account Company A and issue a new invoice.
But HQ actually has this Company A added to database already.
So when KL-User-A export his data from his database and try to import to HQ’s database, system will identify the Debtor Account by its ID.
System now find 2 different ID with same company code, that’s where the error happens.
There are 2 ways to avoid this error:
- Always export the master files from HQ to branches instead of creating the same master files in each branch.
- Change the serialization configuration to identify master file by Company Code, Category Code, instead of by ID.
