Quickly enable or disable users through code

A while ago I got a question from someone how to disable a bunch of users quickly. So I needed a way of end-dating these users so they are unable to login. Of course this can be done by running a dataloader script, by doing a dirty update to the FND_USER table but a more supported way is by using the public procedures of the FND_USER package FND_USER_PKG. A question that can be asked after that.....but how can we enable a user again through code? Let me explain.

Disable an user
Run the below statement to disable a user immediately per sysdate. Take note of the required commit call after the disable procedure. As always change the parameter username to fit your needs.

BEGIN 
FND_USER_PKG.DisableUser(username => 'CSCHAIK');
commit;
END;

After this the user account is assigned an end-date of sysdate and the user status changes to Inactive.

Enable an user
If you want to enable an user again the below snippit can be run.

BEGIN 
FND_USER_PKG.EnableUser(username => 'CSCHAIK');
commit;
END;

This will remove the end-date of the user account and makes it active again. The EnableUser procedure also has optional parameters for the start and end-date of the user. For example running the below command will enable the user per sysdate but setting an end-date of sysdate + 30 days.

BEGIN 
FND_USER_PKG.EnableUser(username => 'CSCHAIK',
                        start_date => sysdate,
                        end_date => sysdate+30);
commit;
END;

The above can also be used to enable an user in the future. For example the below will enable a user per sysdate + 2 days. Note that as per sysdate this user is still Inactive but will become Active 2 days after it.

BEGIN 

FND_USER_PKG.EnableUser(username => 'CSCHAIK',

                        start_date => sysdate+2);

commit;

END;

As always, have fun!
