  Inconsistent Metadata: Changes in the underlying data source or transformations that are not reflected in the InfoProvider can also cause this issue.
  
  Solution:
  
  Check Data Types: Review the key fields of the InfoProvider in the SAP BW modeling tools (like RSA1). Ensure that all components of the key are defined as character type (CHAR).
  Adjust Data Source: If the InfoProvider is based on a data source, check the data source definition and ensure that the key fields are correctly defined as character types.
  Transformation Settings: If you are using a transformation to load data into the InfoProvider, check the transformation settings to ensure that the data types match the expected types in the InfoProvider.
  Rebuild InfoProvider: If necessary, you may need to adjust the InfoProvider definition or even recreate it to ensure that the key fields are correctly defined.
  Check for Updates: Ensure that your SAP system is up to date with the latest support packages and notes, as there may be fixes related to this issue.
