Hi Suneel,
Your question is little vague as the info you have mentioned in not complete. Can you let us know what exactly you are looking for?
By looking at the info you have mentioned it looks like you want to rollback the extraction done from FI datasources. So here is the info might be helpful to you:
1. ROOSGENDLM - This table is actually a generic datasource reference table so you will not find any entry for FI standard datasources. This table has the delta limits and you can play with the entries if you want to reset the deltas or recover the data for generic datasources i.e. custom datasources.
2. BWOM2_TIMEST: This table have the delta pointers for FI/CO datasources. You should not tamper with the entries in this table as it can cause serious data issues in extraction. But there are times when we need to recover the lost delta data if we cannot do a delta repeat for some reason. Then the entries can be handled by using a SE38 program BWOM2_TIMEST, which can be used to reset the delta pointer to previous times.
Please let me know the main issue and I can help you out with delta mechanism of extractors.
Thanks
Amit
