• What is the cause and solution for SAP error message IU757 - No inactive nametab for & of the tables to be converted ?

  The SAP error message IU757 "No inactive nametab for & of the tables to be converted" typically occurs during the process of converting database tables, particularly when using the SAP Upgrade or Migration tools. This error indicates that the system is unable to find an inactive name table (nametab) for the specified table, which is necessary for the conversion process.
  Cause:
  
  Missing Inactive Nametab: The primary cause of this error is that the inactive nametab for the specified table does not exist. This can happen if the table was not properly defined or if there was an issue during a previous upgrade or migration process.
  Table Not Properly Defined: The table may not have been defined correctly in the Data Dictionary (DDIC), or it may have been deleted or modified in a way that affects its nametab.
  Transport Issues: If the table definition was transported from another system, there may have been issues during the transport that led to the nametab not being created.
  
  Solution:
  
  Check Table Definition: Verify the definition of the table in the Data Dictionary (transaction SE11). Ensure that the table exists and is correctly defined.
  Recreate Inactive Nametab: If the inactive nametab is missing, you may need to recreate it. This can typically be done by:
  
  Going to transaction SE11.
  Selecting the table and checking the "Technical Settings."
  If necessary, regenerate the table or its nametab.
  
  
  Check Transport Logs: If the table was transported, check the transport logs for any errors or warnings that might indicate why the nametab was not created.
  Use the Report RDDNEWPP: You can run the report RDDNEWPP to regenerate the nametabs for all tables. This report can help in creating the necessary inactive nametabs for tables that are missing them.
  Consult SAP Notes: Look for relevant SAP Notes that may address this specific error. SAP frequently releases notes that provide solutions or workarounds for known issues.
