  The SAP error message FARR_MSG_CUSTOM028 indicates that there is an issue with the invoice quantity for a performance obligation (Perf. Obl.) in the context of revenue recognition or billing. Specifically, the error states that the invoice quantity for the specified performance obligation exceeds the total quantity that has been defined for that obligation.
  Cause:

  The total quantity for the performance obligation was incorrectly defined.
  There was an attempt to invoice more than what was delivered or agreed upon in the contract.

  Data Entry Error: A simple data entry mistake where the user inputs an incorrect quantity.
