• What is the cause and solution for SAP error message DBMAN026 - Change to content of Infocube &1 is incompatible; restart query ?

  The SAP error message DBMAN026 indicates that there has been a change to the content of an InfoCube that is incompatible with the current state of a query. This typically occurs when the underlying data structure of the InfoCube has been modified (e.g., new characteristics or key figures added, or existing ones changed) while a query is still running or has been executed.
  Cause:
  
  Structural Changes: Changes made to the InfoCube, such as adding or removing characteristics or key figures, can lead to this error.
  Data Loading: If data is being loaded into the InfoCube while a query is being executed, it can cause inconsistencies.
  Query Execution: The query may have been executed before the changes were made, and the system is unable to reconcile the old query structure with the new InfoCube structure.
  
  Solution:
  
  Restart the Query: The simplest solution is to restart the query. This will allow the query to recognize the new structure of the InfoCube.
  Check for Ongoing Data Loads: Ensure that no data loads are in progress when executing queries. If data loads are happening, wait for them to complete before running queries.
  Review Changes: If structural changes were made to the InfoCube, review those changes to ensure they were intended and correctly implemented.
  Clear Query Cache: Sometimes, clearing the query cache can help resolve inconsistencies. This can be done through transaction codes like RSRT (for query execution) or RSADMIN (for cache management).
  Check for Locks: Ensure that there are no locks on the InfoCube that could be causing the issue. You can check for locks using transaction SM12.
  Rebuild the Query: If the issue persists, consider rebuilding the query or checking the query definition for any inconsistencies.
