  Cause:
  This error typically arises in the following scenarios:
  
  
  Incorrect Data Type Definition: The InfoObject or data model has been defined with an incorrect data type for the language field. The language field should be defined as a LANG type, which is a standard data type in SAP for language codes.
  
  
  Data Source Mismatch: If you are loading data from a source system, the data structure in the source may not match the expected structure in the target InfoObject or data model.
  
  
  Transformation Issues: If you are using transformations to map fields from the source to the target, there may be an issue in the mapping where the language field is not correctly defined.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check InfoObject Definition:
  
  Go to the InfoObject in the SAP BW system.

  Adjust Transformations:
  
  If you are using transformations, review the mapping for the language field. Ensure that it is correctly mapped to a field of type LANG in the target.
  
  
  
  Data Load Process:
  
  If the error occurs during a data load process, check the data being loaded. Ensure that the values being loaded into the language field are valid language codes (e.g., 'EN' for English, 'DE' for German).
  
  
  
  Testing:
  
  After making the necessary changes, test the data load or transformation again to ensure that the error is resolved.
