  The message text typically is:
  
  Error when inserting table &
  
  where & is replaced by the actual table name, in your case TWISPC_ZMERK_W.
  
  
  Cause
  The error WXP781 occurs during an attempt to insert data into a database table, and it usually indicates a problem at the database or application layer related to the insert operation. Common causes include:
  
  
  Primary Key or Unique Constraint Violation
  
  Attempting to insert a record with a key that already exists in the table.
  
  
  Missing or Incorrect Data
  
  Mandatory fields are missing or contain invalid data that violates database constraints.
  
  
  Authorization Issues
  
  The user or process does not have the necessary authorization to insert data into the table.
  
  
  Database Lock or Deadlock
  
  The table or row is locked by another process, preventing the insert.
  
  
  Technical Issues  
  
  Database connection problems.  
  Buffer or memory issues in the SAP application server.  
  Inconsistent or corrupted table buffers.
  
  
  
  Custom Table or Enhancement Issues
  
  Since TWISPC_ZMERK_W looks like a custom or Z-table (due to the Z in the name), the insert logic might be part of a custom enhancement or user exit that has errors or missing handling.
  
  
  
  Solution
  To resolve the WXP781 error when inserting into TWISPC_ZMERK_W, follow these steps:
  
  
  Check the Key Fields  
  
  Verify that the primary key or unique key fields in the insert data are unique and not already existing in the table.  
  Use SE16/SE16N or SE11 to check existing entries.
  
  
  
  Validate Data Consistency  
  
  Ensure all mandatory fields are filled correctly.  
  Check data types and lengths.
  
  
  
  Check Authorizations  
  
  Verify that the user or background job has the necessary authorizations to insert into the table.  
  Use transaction SU53 after the error occurs to check authorization failures.
  
  
  
  Check for Locks  
  
  Use transaction SM12 to check if there are locks on the table or related entries.  
  If locks exist, investigate and release if appropriate.
  
  
  
  Review Custom Code  
  
  Since the table is custom, check any custom programs, function modules, or BAdIs that perform the insert.  
  Debug the insert logic to identify if the error is raised due to application logic.
  
  
  
  Check System Logs and Dumps  
  
  Use transaction ST22 to check for short dumps related to the insert operation.  
  Use SM21 to check system logs for database or application errors.
  
  
  
  Database Consistency Check  
  
  Run database consistency checks if you suspect corruption.  
  Consult your Basis team for database-level troubleshooting.
  
  
  
  Buffer Refresh  
  
  If the table is buffered, try refreshing the buffer using transaction SE14 or program RSDBUF to avoid stale data issues.
