user & tcode logs
In our environment there was issue with mrp run in PP module.
We tested at our end and found that it was not functioning properly.So we put message to SAP support .
They accessed our system and replied that there is no problem with functionality .
So we again tested it and found that it is working fine,
Now we want to know where exactly the problem was?
We tried to find the log to see if anyone has made any changes ?
But we are not getting through.So if anyone can guide us to find the log where we can see those changes which any user has done?
Or log for how SAP support team tested our data ?
Tcode which we used to check log is st03n , sm21 , stad
