• What is the cause and solution for SAP error message AMDP_DBG021 - DEBUG operation "&1" failed (error code "&2", error message "&3"). ?

  The SAP error message AMDP_DBG021 indicates that a debug operation for an ABAP Managed Database Procedure (AMDP) has failed. This error typically arises during the debugging of AMDPs, which are used to execute database procedures directly from ABAP.
  Cause:
  The error can be caused by several factors, including:
  
  Database Connection Issues: There may be a problem with the connection to the database where the AMDP is being executed.
  Syntax Errors: There could be syntax errors in the SQL code or the AMDP itself.
  Runtime Errors: The AMDP might be encountering runtime errors due to data issues or logic errors in the code.
  Debugging Configuration: The debugging environment may not be properly configured, or there may be restrictions on debugging certain types of database operations.
  Authorization Issues: The user may not have the necessary authorizations to execute the AMDP or to debug it.
  
  Solution:
  To resolve the AMDP_DBG021 error, you can take the following steps:
  
  
  Check Database Connection: Ensure that the connection to the database is active and functioning correctly. You can test the connection using transaction codes like DBACOCKPIT or DB02.
  
  
  Review AMDP Code: Check the AMDP code for any syntax errors or logical issues. Make sure that the SQL statements are valid and that they can be executed without errors.
  
  
  Debugging Configuration: Ensure that the debugging environment is set up correctly. You may need to check the settings in the ABAP Development Tools (ADT) or the SAP GUI.
  
  
  Check Authorizations: Verify that the user has the necessary authorizations to execute and debug the AMDP. You can check the user's roles and authorizations in transaction SU01.
  
  
  Use Transaction ST22: If the error is due to a runtime issue, check transaction ST22 for any short dumps that may provide more information about the error.
  
  
  Check for Locks: Ensure that there are no database locks that could be preventing the AMDP from executing.
  
  
  Consult SAP Notes: Look for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  
  
  Related Information:
  
  AMDP: ABAP Managed Database Procedures allow you to write database procedures in ABAP that can be executed directly on the database, improving performance by reducing data transfer.
  Debugging AMDPs: Debugging AMDPs can be more complex than standard ABAP debugging due to the interaction with the database. Familiarize yourself with the specific debugging tools and techniques for AMDPs.
  SAP Community: Consider searching or posting in the SAP Community forums for additional insights or similar experiences from other users.
