Hello,
I'm saying isolation will not work out to my requirement. The steps.
1. On completion of all entries by all, say for a day.
2. Lock, so that no one enters any other data.
3. Create a report from the entered data.
4. Create / Modify required entries from the values arrived in the report. [ long process ]
5. Once completed, commit all data.
6. Unlock, so that other users can enter data again. Data entered will be for another date. Data cannot [should] not entered for the processed date.

maybe advisory lock is what you need?
