  The SAP error message M8_2123 indicates that there is an issue with using IDocs (Intermediate Documents) in conjunction with differential invoicing. This error typically arises when there is an attempt to process an IDoc that is not compatible with the differential invoicing functionality in SAP.
  
  Cause:
  The primary cause of this error is that differential invoicing is a specific invoicing method that is not supported for certain types of IDocs.

  Solution:
  To resolve this error, consider the following steps:
  
  
  Check IDoc Type: Ensure that the IDoc type you are using is compatible with the differential invoicing process. You may need to use a different IDoc type that supports standard invoicing.
