Hi Jonathan,
Thanks for replying to this message.
I agree with all your points and also I see the same results when I execute the different methods.
However, using the Adhoc query related t-code throwing a dump, due to its taking lot of time for giving an output to the user and few HR key users are wants to have a faster output method. this requirement is not possible with the AdHoc query related t-code.
Because this Adhoc query t-code doesn't have an option to execute the report in the background. this a appraisal review time and they have been evaluating the lot of employees data on the company\country level in the system.
As I see Adhoc reports related t-code doesn't meet their requirement. Hence, T-code SQ01 has an option to execute the report in 20 sec (background) whereas the same report has been taking more than 45 min's with AdHoc query (also users are getting the dumps)
I agree with your point that HR reports are very crucial\sensitive information and all the user should not have an access to the SQ01.
SQ01 will be given to the Key users only and also possible to restrict the query access in the t-code SQ03.
