• What is the cause and solution for SAP error message RSLWSP490 - Data type properties changed for column &1 in local physical storage &2 ?

  The SAP error message RSLWSP490 indicates that there has been a change in the data type properties for a specific column in a local physical storage object. This typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when there are inconsistencies between the data model and the underlying database structure.
  Cause:
  
  Data Type Change: The most common cause is that the data type of a column in the InfoObject or data model has been modified (e.g., from CHAR to NUMC or vice versa) after the data has already been loaded into the physical storage.
  Inconsistent Metadata: There may be inconsistencies between the metadata definitions in the SAP BW system and the actual physical storage in the database.
  Transport Issues: If changes were transported from one system to another (e.g., from development to production), the transport might not have been executed correctly, leading to mismatches.
  
  Solution:
  
  Check Data Type Changes: Review the data model and InfoObject definitions to ensure that the data types are consistent with the physical storage. If changes were made, consider reverting them or updating the physical storage accordingly.
  Rebuild the Data Model: If the data type changes are necessary, you may need to rebuild the data model or the InfoProvider to align the physical storage with the new definitions. This can often be done through the Data Warehousing Workbench.
  Data Load: After making the necessary adjustments, perform a data load to refresh the data in the physical storage. This will ensure that the data is consistent with the new definitions.
  Check Transport Logs: If the issue arose after a transport, check the transport logs for any errors or warnings that might indicate problems during the transport process.
  Use Repair Tools: SAP provides tools to repair inconsistencies in the data model. You can use transaction codes like RSBAS000 or RSBAS002 to check and repair inconsistencies.
