  SAP Error Message:
  WXP780 Error when inserting table TWISPC_ZMERK: &?
  
  1. Cause of the Error
  
  
  Context:
  
  The error message WXP780 typically occurs in the context of Web Dynpro ABAP applications when there is an issue inserting data into an internal table or database table.
  
  
  Specific Cause:
  
  The message indicates that an error happened during the insertion of a record into the table TWISPC_ZMERK. The placeholder &? usually contains additional information or the key value that caused the problem, but if it appears as &? it might mean the system could not resolve the variable or the message text is incomplete.
  
  
  Possible reasons include:  
  
  The table TWISPC_ZMERK is a custom or Z-table, and the insertion violates some database constraints (e.g., primary key violation, unique constraint, or foreign key constraint).  
  The internal table or database table is not properly initialized or declared.  
  Data type mismatch or incorrect data format in the fields being inserted.  
  Authorization issues preventing the insert operation.  
  The table might be buffered and the buffer is out of sync.  
  The insert statement is syntactically incorrect or the program logic is flawed.
  
  
  
  
  2. Solution
  
  
  Check the Table Definition:
  
  Verify the structure of TWISPC_ZMERK in SE11. Check for primary keys, unique indexes, and foreign key constraints.
  
  
  Analyze the Data Being Inserted:
  
  Debug the program or Web Dynpro component to check the exact data values being inserted. Look for duplicates or invalid data.
  
  
  Check for Duplicate Entries:
  
  If the table has a primary key, ensure that the record you are trying to insert does not already exist.
  
  
  Review the Insert Statement:
  
  Make sure the insert statement is correct. For example, in ABAP:  
  INSERT INTO twispc_zmerk VALUES wa_zmerk.
  Ensure wa_zmerk is properly populated.
  
  
  Check Authorizations:
  
  Ensure the user executing the insert has the necessary authorizations to modify the table.
  
  
  Check Buffering:
  
  If the table is buffered, try to refresh the buffer or disable buffering temporarily to test.
  
  
  Look at System Logs:
  
  Use transaction ST22 (Dump Analysis) or SM21 (System Log) to find more detailed error information.
  
  
  Enhance Error Handling:
  
  Modify the program to capture the exact error message after the insert statement, for example:  
  INSERT twispc_zmerk FROM wa_zmerk.
  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.
  This will give more precise error details.
