  The SAP error message CL564 ("Change with change number not allowed on the date you entered") typically occurs in the context of change management within SAP, particularly when dealing with change numbers in the classification system or when managing changes to materials or documents.
  Cause:
  This error message is triggered when you attempt to make a change to a classification or a material using a change number that is not valid for the date you have specified. The reasons for this could include:
