  TCNN is a standard SAP table that stores Web Dynpro component metadata.

  Solution / How to Fix:
  
  
  Check for Locks:
  
  Use transaction SM12 to check if the TCNN table entries are locked.
  If locks exist and are stale, release them carefully.

  Verify that the user performing the update has the necessary authorizations, especially for Web Dynpro development and table maintenance.
  Relevant authorization objects include S_DEVELOP, S_TABU_NAM (for table maintenance), and Web Dynpro specific authorizations.
  
  
  
  Check Table Consistency:
  
  Run database consistency checks for TCNN.
  Use transaction SE14 (Database Utility) to check and repair the table if necessary.
  
  
  
  Re-import or Re-transport Web Dynpro Components:
  
  If the error occurred after a transport, re-import the transport or check for transport inconsistencies.
