Hi,,

You can do like this.. Take any variable and add 1 to it in the PBO of the next screen when user goes to next screen. And give a check condition on the PBO of the first screen like if Var = 0. give a error message accordingly and restrict it to enter on to the next screen.

reset the value of the var when the user leaves the next screen.

Hi,

Please note my understanding is correct.

you want the user to enter the user ID and Password first time and if it these details are correct then he can go to next screen.

if there are not correct , then you dont want the user to enter the details again Am i Correct.

if he enters wrong details make the USER_ID and PASSWORD grey mode

if so Please try this.

in PAI.

chain.

field : user_id, password.

module check_user_id on request.

endchain.

in program.

module check_user_id.

if not user_id is initial and not password is initial.

select the details from dbtable and check the sy-subrc.

if not sy-subrc is initial.

entry_wrong = 'X'. declare entry_wrong in top include

else.

call screen next_screen.

endif.

in PBO.

if entry_wrong.

loop at screen.

if screen-name = 'USER_ID' or

screen-name = 'PASSWORD'.

screen-input = 0.

modify screen.

endif.

endloop.

endif.

endmodule.

Hi,


  INput:User name And Password..
if any one type it has to update in a table... if any one modify the password that also have to be updated

to create password field , check the invisible checkbox in field attribute.
create ztable to save the user name and password.

when 'UPDA'.
ipass-zuname = zpassword-zuname.
ipass-zpassword = zpassword-zpassword.
modify zpassword from ipass.
when 'MODI'.
ipass-zuname = zpassword-zuname.
ipass-zpassword = zpassword-zpassword.
modify zpassword from ipass.

Thanks & Regards,

Krishna...

Hi,

you mean you want to restrict multiple logons.

so for this you need to call the system function 'ThUsrInfo'.

please refer to this link which will be very helpful:

Hi Suresh ,

What I understand of your problem is that

suppose a user A has logged in the system and user B wants to log in the system with userid and password of user A then you want to restrict user B from not entering the system .

You can do it in 2 ways :

I take that u have database table say zuser from where ur gettinh user id & password

Method 1 :

You make another column in Zuser which has datatype C and once the user logs in put the value to that user as 'X' and as soon as user logs out clear the field against his name in database .

So querry goes as

select * from zuser

where userid = sy-uname

and password = <password>

and <new_column> = ' ' .

if sy-subrc ne 0 .

Throw Error Message .

endif .

Method2:

Make a record level data base lock which can help u out .

Thanks
