How do you know what user to select?
Start there.

[dheeru_1994]

i make user inactive and that inactive user  i select in user activity 
if i push any other user sys _id and test both approver are comming in requested item table 
and 
i write the script in advance 

answer = [];

function isUserActive(userID) {

    var user = new GlideRecord('sys_user');

    if (user.get(userID)) {

        return user.active == true;

    }

    return false;

}

var selectedUserID = 'a8f98bb0eb32010045e1a5115206fe3a';

if (isUserActive(selectedUserID)) {

    answer.push(selectedUserID);

    gs.info("Selected user is active.");

} else {

    gs.info("Selected user is inactive.");

}

but how the script check that this is active user or not
