• What is the cause and solution for SAP error message FSC1026 - Assignment to main transactions is not possible (application &1) ?

  The SAP error message FSC1026, which states "Assignment to main transactions is not possible (application &1)," typically occurs in the context of financial transactions, particularly when dealing with the assignment of sub-transactions to main transactions in the SAP system. This error can arise in various applications, such as Financial Accounting (FI) or Controlling (CO).
  Cause:
  The error can be caused by several factors, including:
