Dear Abhijit,
If I login in the system first time, and run the report, it shows me wrong data and after that, I just press Back and execute the report, it shows correct data for the same parameters.
If I change the parameters value(Like date) at every execution, report shows wrong data every time.
After the first execution, all next executions shows correct data for same parameters.
If I logged out and login after 4-5 hours and run the same report with same parameters, the report again shows me wrong data.
Take an example:
>>>Login.
1. I run the report with date 10.08.2014 = Return wrong value.
2. I run the report with date 10-08.2014 = Return correct value.
3. I run the report with date 15.08.2014 = Return wrong value.
4. I run the report with date 16.08.2014 = Return wrong value.
5. I run the report with date 15.08.2014 = Return Correct value.
>>> Log out and Login after 4-5 hours.
6. I run the report with date 10.08.2014 = Return wrong value.
7. I run the report with date 10.08.2014 = Return correct value.
Regards.
