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.
