Answer Posted / s.m.feroz ahmed

Hi,

SAP Application Server is designed in such a manner that if
a same Tcode is being used by different users at same
instance of time then a lock is enable at back ground
unless the first user comes out of the T Code SU01 and the
second user who is trying to make use of the same Tcode
SU01 at the same time then this user will not be able to
access that Tcode SU01 till the previous user comes out of
that TCode SU01 .one can view the logged in user
information and Tcode being used with the help of
TCode "SM50 for locally logged in users and SM66 for
globally logged in users.So,for this reason you are not
able to access Tcode SU01 the previous day and was able to
access the same code next day.
