Hi Experts,

First person works his Username and password are allowed to access the next screen only but its restrict it. second person knew First person's username and password but second person donot allow to access one person's same username and password.. can u understand???

if u can understand then send me how is performed it??

Hi,

try using SELECT SINGLE FOR UPDATE to set an exclusive lock

so that when the other users try to access it you can give an error message saying

Multiple logons are not permitted with the same user

or create Lock Objects in SE11 they start with EY or EZ and they also generate two function modules which you can use in the program

for more info please go through the KEY word Docu

The steps in SE11 are self explanatory.
