Hi Jurgen,
Yes, client do copy from production to test systems? But how would i come to know when was the copy done? These messages are processed successfully and mail has been sent to supplier from production system which is causing problem. When i check the NAST table, i saw the creation date as 09.09.2014 and time from 12 pm, every entry has started sending to supplier at regular interval.
Regards,
Prasath J
