  The SAP error message IU459, which states "Deletion of ICNV nametab for table & failed," typically occurs in the context of data dictionary operations, particularly when dealing with the conversion of data types or structures in the SAP system. This error can arise during the deletion of an internal conversion (ICNV) name table for a specific database table.
  Cause:
  
  Data Dictionary Changes: The error often occurs when there are changes made to the data dictionary, such as deleting or modifying a table that has associated conversion routines.
  Dependencies: There may be existing dependencies or references to the conversion routines that prevent the deletion from being completed successfully.
  Authorization Issues: Lack of proper authorizations to perform the deletion operation can also lead to this error.
  System Lock: The table or its associated objects might be locked by another process, preventing the deletion.
  
  Solution:
  
  Check Dependencies: Use transaction SE11 (Data Dictionary) to check if there are any dependencies or references to the conversion routines associated with the table. Ensure that all dependencies are resolved before attempting to delete.
  Review Authorizations: Ensure that you have the necessary authorizations to perform the deletion. You may need to consult with your SAP security team if you suspect authorization issues.
  Release Locks: If the table is locked, identify the process that is holding the lock and release it. You can use transaction SM12 to check for and manage locks.
  Manual Deletion: If the automatic deletion fails, you may need to manually remove the conversion routines associated with the table. This can be done in transaction SE11 by navigating to the relevant conversion routine and deleting it.
  Transport Requests: If the changes are part of a transport request, ensure that the transport is correctly configured and that there are no issues with the transport system.
  
  Related Information:
