• What is the cause and solution for SAP error message FH518 - No longer possible to change account numbers (see long text) ?

  The SAP error message FH518, which states "No longer possible to change account numbers (see long text)," typically occurs when there is an attempt to change account numbers in a financial document or master data that has already been posted or processed.

  Reversing the Document: If possible, reverse the document and create a new one with the correct account number.
