• What is the cause and solution for SAP error message RSD_TREX162 - Typ of attribute '&1' in index of table '&2' changed ?

  The SAP error message RSD_TREX162 indicates that there is a mismatch in the type of an attribute in the index of a table. This typically occurs in the context of SAP BW (Business Warehouse) when there are changes made to the data model or the underlying data sources that affect the attributes of InfoObjects.
  Cause:
  
  Data Model Changes: The attribute type of an InfoObject has been changed in the data model (e.g., from CHAR to NUMC or vice versa).
  Data Source Changes: Changes in the underlying data source (like a change in the database schema) that affect the data type of the fields being used in the InfoObject.
  Inconsistent Metadata: The metadata in the BW system is inconsistent with the actual data in the underlying database or the data source.
  
  Solution:
  
  Check the InfoObject Definition: Verify the definition of the InfoObject in the SAP BW system. Ensure that the attribute types are correctly defined and match the data types in the source system.
  Re-activate the InfoObject: If changes have been made to the InfoObject, re-activate it in the InfoObject maintenance transaction (transaction code: RSA1).
  Rebuild the Index: If the error persists, you may need to rebuild the index for the affected InfoObject. This can be done by:
  
  Going to the InfoProvider in RSA1.
  Selecting the InfoObject and choosing the option to "Rebuild Index".
  
  
  Check Data Source: If the issue is related to a data source, ensure that the data source is correctly configured and that the data types in the source system match those in the BW system.
  Transport Requests: If the changes were made in a development environment, ensure that the transport requests are correctly moved to the production environment without any inconsistencies.
