  The SAP error message RSDRV_VPROHANA022 indicates a data type mismatch between a navigation attribute and its corresponding attribute in a data model, typically in the context of SAP HANA or SAP BW (Business Warehouse). This error usually arises when the data types of the navigation attribute and the base attribute do not match, which can lead to issues in data processing or reporting.

  Re-activate Objects: After making changes, re-activate the affected InfoObjects or data models to ensure that the changes take effect.
  
  
  Check for Dependencies: If the attributes are used in other models or queries, ensure that those dependencies are also updated to reflect the changes.
