change log in MIR4

Hi Everyone,

I have an issue where someone from user team is doing some changes in screen layout of MIR4 t code by going to tab CONFIGURATION > ADMINISTRATION. That user is making fields invisible for this purpose but its impacting all the user acroos.

Now we are not able to find that which user is doing that change so that we can ask him not to do any change again.

Kindly help on this.

Regards
