  SAP Error Message:
  
  WXP805 Error when updating table TCNG: &
  
  Cause
  The error WXP805 occurs during an attempt to update the SAP table TCNG, which stores configuration data for the SAP Web Dynpro framework (specifically, the Web Dynpro configuration). This error typically indicates that the system encountered a problem while trying to write or update entries in the TCNG table.
  Common causes include:
  
  Locking issues: The table or relevant entries are locked by another process, preventing the update.
  Authorization problems: The user performing the update lacks the necessary authorizations to modify the TCNG table.
  Inconsistent or corrupted data: The data being written violates table constraints or is inconsistent.
  Transport or system inconsistencies: If the update is part of a transport or system upgrade, inconsistencies or missing dependencies can cause the error.
  Database issues: Underlying database problems such as missing indexes, corrupted entries, or insufficient space.
  
  
  Solution
  To resolve the WXP805 error when updating TCNG, follow these steps:
  
  
  Check for Locks:
  
  Use transaction SM12 to check if the TCNG table or related entries are locked.
  If locks exist and are stale, consider releasing them carefully.
  
  
  
  Verify Authorizations:
  
  Ensure the user has the necessary authorizations to update Web Dynpro configurations.
  Typically, authorizations related to Web Dynpro development and configuration (e.g., S_DEVELOP, S_TABU_NAM for table maintenance) are required.
  
  
  
  Check Data Consistency:
  
  Review the data being updated for correctness.
  If the update is manual or via a program, validate the input data.
  
  
  
  Use Standard Transactions:
  
  Perform updates via standard SAP transactions or tools (e.g., Web Dynpro configuration transactions) rather than direct table updates.
  
  
  
  Check Transport Logs:
  
  If the error occurs during a transport import, check the transport logs for related errors.
  Re-import or correct the transport if necessary.
  
  
  
  Database Health Check:
  
  Run database consistency checks.
  Consult your Basis team to verify database integrity and space.
  
  
  
  SAP Notes and Support:
  
  Search for SAP Notes related to WXP805 and TCNG updates.
  For example, SAP Note #XXXXXX (replace with actual note number if found) might provide patches or detailed instructions.
  
  
  
  Recreate or Reset Configuration:
  
  In some cases, resetting or recreating the Web Dynpro configuration entries can help.
  Use transaction SE38 to run relevant reports or tools for Web Dynpro configuration maintenance.
