• What is the cause and solution for SAP error message RAP_CMP_CHECKS091 - Number of decimal places decreased for property &1 of entity type &2. ?

  The SAP error message RAP_CMP_CHECKS091 indicates that there is a mismatch in the number of decimal places defined for a property in an entity type within the RAP (Rapid Application Programming) model. This typically occurs when the decimal places for a property in the data model are being reduced or changed in a way that is not compatible with existing data or definitions.
  Cause:
  
  Model Definition Changes: The error often arises when there is a change in the definition of an entity type, specifically when the number of decimal places for a property is decreased.
  Inconsistent Data: If there is existing data that has more decimal places than what is now defined in the model, this inconsistency can trigger the error.
  Data Type Mismatch: The property might be defined with a different data type or precision in the underlying database or in the service definition.
  
  Solution:
  
  Review Entity Definition: Check the definition of the entity type and the specific property that is causing the error. Ensure that the number of decimal places is consistent with the data being processed.
  Adjust Decimal Places: If the change in decimal places is intentional, consider adjusting the existing data to match the new definition or revert the definition to maintain compatibility with existing data.
  Data Migration: If you need to change the decimal places, you may need to perform a data migration to round or truncate existing data to fit the new definition.
  Check Service Implementation: Ensure that any service implementations or consumption of the entity type are also updated to reflect the new definition.
  Testing: After making changes, thoroughly test the application to ensure that the error is resolved and that the application behaves as expected.
