• What is the cause and solution for SAP error message FI663 - You must not change assignment to company code & ?

  The SAP error message FI663 ("You must not change assignment to company code &") typically occurs when there is an attempt to change the assignment of a master data object (like a vendor, customer, or general ledger account) to a different company code in a way that is not allowed by the system configuration or business rules.
  Cause:
  
  Company Code Assignment: The object (e.g., vendor or customer) is already assigned to a specific company code, and the system does not allow changing this assignment due to configuration settings or business rules.
  Data Integrity: SAP enforces data integrity rules to ensure that financial data remains consistent and accurate across different company codes.

  Authorization Issues: The user may not have the necessary authorizations to make changes to the company code assignment.

  Use Correct Transaction: Ensure that you are using the correct transaction code for the operation you are trying to perform. For example, if you are trying to change a vendor's company code assignment, you may need to use a specific transaction designed for that purpose.
