Hi,
There are many ways to find it.
go in se03 in your system and then give below details.
Search for Objects in Requests/Tasks
PGMID R3TR Obj VDAT V_TCURR
This will show you what all changes are done on the V_TCURR.
Or go in Sm30 and give V_TCURR and then display ---> utility and then change log.
Thanks
