• What is the cause and solution for SAP error message RSDD_CS050 - The data type of the SAP HANA model is not compatible with InfoObject &1 ?

  The SAP error message RSDD_CS050 indicates that there is a data type mismatch between a SAP HANA model and an InfoObject in SAP BW (Business Warehouse). This typically occurs when the data type defined in the HANA model does not align with the data type expected by the InfoObject.
  Cause:
  
  Data Type Mismatch: The most common cause is that the data type of a field in the SAP HANA model does not match the data type of the corresponding InfoObject. For example, if the InfoObject is defined as a character type but the HANA model field is defined as a numeric type, this error will occur.
  Changes in Data Model: If there have been recent changes to the HANA model or the InfoObject, such as changing the data type or length, this can lead to incompatibility.
  Inconsistent Metadata: If the metadata in the BW system is not updated to reflect changes made in the HANA model, it can lead to this error.
  
  Solution:
  
  
  Check Data Types: Verify the data types of the fields in both the SAP HANA model and the InfoObject. Ensure that they are compatible. You can do this by:
  
  Going to the SAP HANA model in the HANA Studio or Web IDE and checking the data type of the relevant fields.
  Checking the InfoObject in the SAP BW system to see its data type.
  
  
  
  Modify Data Types: If there is a mismatch, you may need to either:
  
  Change the data type in the HANA model to match the InfoObject.
  Change the data type of the InfoObject to match the HANA model, if appropriate.
  
  
  
  Update Metadata: After making changes, ensure that the metadata in the BW system is updated. This can be done by:
  
  Activating the InfoObject again.
  Refreshing the data source or reloading the data.
  
  
  
  Check for Other Dependencies: If the InfoObject is used in other models or queries, ensure that changing its data type does not affect those dependencies.
  
  
  Testing: After making the necessary changes, test the data load or query to ensure that the error is resolved.
