Hi Ganesh,
Ideally you should get the desired data, since above data-sources are directly fetching data from above mentioned tables.
Did you tried to check the data in RSA3? Hope there is no selections maintained at infopackage level!
As per my knowledge FAGLFLEXA table is for Actual data and FAGLFLEXT is for Plan data.
If you did all the checks what I mentioned above, last option we left is generic data source extraction based on view.
Thanks & Regards,
Harish
