• What is the cause and solution for SAP error message RAP_CMP_CHECKS094 - Precision changed for property &1 of entity type &2. ?

  The SAP error message RAP_CMP_CHECKS094 indicates that there is a precision mismatch for a property in an entity type within the context of the SAP RAP (Rapid Application Programming) model. This typically occurs when the precision of a numeric property in the data model does not match the precision defined in the underlying database or when there is an inconsistency in the data model definitions.
  Cause:
  
  Precision Mismatch: The precision of a numeric property in the entity type is defined differently than what is expected or what is defined in the database schema.
  Model Changes: Changes made to the data model (e.g., changing the precision of a property) without corresponding updates in the database schema can lead to this error.
  Inconsistent Definitions: If the entity type is defined in multiple places (e.g., in different CDS views or service definitions), inconsistencies can arise.
  
  Solution:
  
  Check Entity Definition: Review the entity type definition in your CDS (Core Data Services) view or RAP model. Ensure that the precision of the property matches the expected precision.
  Database Schema Update: If the precision has been changed in the entity definition, ensure that the underlying database schema is updated accordingly. This may involve altering the database table to match the new precision.
  Consistency Check: Run consistency checks on your RAP model to identify any discrepancies between the model and the database schema.
  Rebuild the Model: If necessary, regenerate the RAP artifacts to ensure that all definitions are consistent and up to date.
  Consult Documentation: Refer to SAP documentation for any specific guidelines related to precision and data types in RAP models.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance.
