  The SAP error message IU445 indicates that there is an issue with the inactive name table (ICNV) for a specific table in the SAP system. This error typically arises when the system is trying to access a name table that has not been activated or does not exist.
  Cause:
  
  Inactive Name Table: The name table for the specified database table has not been activated. This can happen if the table was recently created or modified and the corresponding name table was not generated or activated.
  Missing Name Table: The name table may not exist at all due to a system error or an incomplete transport.
  Transport Issues: If the table was transported from another system, the transport might not have included the necessary name table.

  Check for Missing Objects:

  Re-transport the Objects:
  
  If the issue arose after a transport, consider re-transporting the objects from the source system to ensure that all components are included.
