• What is the cause and solution for SAP error message C1233 - Decimal places cannot be reduced; permitted values already entered ?

  The SAP error message C1233, "Decimal places cannot be reduced; permitted values already entered," typically occurs in the context of configuring or changing the number of decimal places for a field in a master data record or transaction. This error indicates that you are trying to reduce the number of decimal places for a field that already has values entered with a higher precision than what you are attempting to set.
  
  Cause:
  
  Existing Data: The primary cause of this error is that there are already existing entries in the system that have more decimal places than what you are trying to set. For example, if you have values with 3 decimal places and you attempt to change the field to allow only 2 decimal places, SAP will prevent this change to avoid data inconsistency.
