This typically occurs in the context of data extraction, transformation, or reporting processes within SAP BW (Business Warehouse) or SAP BI (Business Intelligence).
  Cause:
  The error arises when:
  
  An InfoObject is expected to be of a certain type (e.g., characteristic, key figure, etc.), but the actual data being processed does not match this expected type.

  The data source or the data being loaded into the InfoObject may not conform to the expected format or type.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check InfoObject Definition:
  
  Go to the InfoObject definition in the SAP BW system and verify that the data type is correctly defined. Ensure that it matches the expected type in the context where it is being used.
