Solution :

1> List the tables that you can exclude from cloning ( Tables that can be excluded and has no impact )

2> Create a file with the table list

eg: File name : EUCLONEDEFS_ADD.LST

      Path : /usr/sap/S12_upg/SUM/abap/var

      Format : <Tablename> noclone

Helpful Points:

•  /usr/sap/S12_upg/SUM/abap/control has the EUCLONEDEFS_ADD.LST which has the supporting information and the log files from the /usr/sap/S12_upg/SUM/abap/log directory.
• Place the file in /bin or /control if the above option did not work
