Hi,
Here you need to find the time when last delta was success fully loaded to bw.
Please check at PSA and find the last delta which was green or successfully loaded to psa.
For example:
you loaded last delta to PSA at 09 October 2014 10:00AM PST.
Today request you deleted. So you can take yester day time 10:00AM to till to day time(now).
take FI team help and find the records which are chanegd/created between yester day 10:00pm to till today .
at repair full info pack you need to use selectiosn on calday/time fields.
I think your next delta will won't work. you may need to do the re init.
But careful. mean while discuss with TL and PM, later you can take action.
Thanks
