  The SAP error message AQV338, which states "Logical database selections cannot be changed," typically occurs when there is an attempt to modify the selection criteria of a logical database in a way that is not permitted.

  Check Logical Database: Review the logical database you are using and ensure that you are not trying to change any of its predefined selection criteria. If you need different selections, consider using a different logical database or creating a custom report.
  Use Variants Properly: If you are using a variant, ensure that it is compatible with the logical database. You may need to create a new variant that adheres to the selection criteria of the logical database.
  Authorization Check: Verify that you have the necessary authorizations to make changes to the report or selection criteria. If not, contact your SAP administrator to obtain the required permissions.
  Consult Documentation: Refer to SAP documentation or help resources for the specific logical database you are working with to understand its limitations and how to work within them.
