• What is the cause and solution for SAP error message C1084 - Number of decimal places can only be reduced ?

  The SAP error message C1084, "Number of decimal places can only be reduced," typically occurs when you are trying to change the number of decimal places for a field in a way that increases the precision, which is not allowed in SAP. This error is often encountered in the context of financial data, where the number of decimal places for currency or quantity fields is defined in a way that ensures data integrity.
  Cause:
  
  Field Definition: The field in question has a predefined number of decimal places, and you are attempting to increase this number. For example, if a field is defined to have 2 decimal places, you cannot change it to 3 decimal places.

  Check Field Settings: Review the field settings in the relevant configuration or data dictionary (e.g., using transaction SE11 for data elements) to understand the current definition and limitations.
  Data Migration: If you are migrating data or changing configurations, ensure that the data being imported or modified adheres to the existing decimal place settings.
  Consult Documentation: Refer to SAP documentation or consult with your SAP Basis or functional team for guidance on how to properly adjust field definitions without violating the rules.
