• What is the cause and solution for SAP error message 64528 - Reverse not possible since flows already posted after & ?

  The SAP error message "64528: Reverse not possible since flows already posted after &" typically occurs in the context of financial transactions, particularly when attempting to reverse a document or transaction that has already been followed by subsequent postings. This error indicates that the system cannot reverse the original transaction because there are subsequent entries that depend on it.

  Subsequent Postings: The primary cause of this error is that there are one or more transactions that have been posted after the transaction you are trying to reverse. This creates a dependency that prevents the reversal.
