Hi Rishi,
I also studied SAP Note 1447267 as mentioned by you and found solution in line stated that "These are listed in the file RADCUCNTNEW.ELG in DIR_PUT/log with error message DO 538 " and You can ignore the errors in this case.
Under RADCUCNTALL.ELG log file message for the DD source tables is DO 538 means we can ignore these errors.
Thanks for support.
Regards,
Gaurav Rana
