System throws error message : Company ABC: Already assigned to a different Set of Books



You can only create additional sets of books and assign company if there are no journal entries in an existing set of books. The reason is to prevent inconsistencies in the further document processing.

For example if you want to process a payment after the second set of books has been assigned, the system needs to read the accounting document that was created by the (previous) invoice the payment wants to clear. For the new set of books, this accounting document would be missing, thus preventing the payment to be processed even for the old set of books.

A company can have different Set of Books attached to it, but this activity needs to be performed before doing any postings in the system. Once postings are made in the system, you cannot assign new Set of Books to the company.


This is expected system behavior and cannot be changed.
