• What is the cause and solution for SAP error message IDGT_LC040 - Unable to merge billing documents due to rounding error ?

  The SAP error message IDGT_LC040, which indicates "Unable to merge billing documents due to rounding error," typically arises during the billing process when there are discrepancies in the amounts due to rounding differences.
