SC_TASK Variable Relationship Script

DylanBlumenberg · ‎06-05-2025

Hey everyone, I'm trying to create a relationship on the sc_task table and I'm running into some issues. The goal is to take the value of the employee_number catalog item variable from the current record and look up any other sc_task records that contain that same value on the employee_number variable. Below is what I have so far but it's returning every sc_task record in the system. Does anyone know where I went wrong?

Things worth noting:

'Applies to table' and 'Queries from table' are both sc_task.
There is a normal variable named employee_number and a variable set variable named employee_number. This script should look for values from both variables.
In the log, gs.info is returning the correct employee_number variable.

(function refineQuery(current, parent) {

    var employeeNumber = parent.request_item.variables.employee_number;
    gs.info('Related List Debug. Value found is: ' + employeeNumber);

    current.addQuery('request_item.variables.employee_number', employeeNumber);

})(current, parent);

@DylanBlumenberg

variables are linked with RITM and not with sc_task

Something like this should work, assuming you want to see related sc_tasks with same variable value

(function refineQuery(current, parent) {

    var employeeNumber = parent.request_item.variables.employee_number;
    var variableSysId = ''; // give here the sysId of that variable from item_option_new table
    var ritmArr = [];
    var gr = new GlideRecord("sc_req_item");
    gr.addQuery("variables." + variableSysId, employeeNumber);
    gr.query();
    while (gr.next()) {
        ritmArr.push(gr.getUniqueValue());
    }
    current.addQuery('request_item.sys_id', 'IN', ritmArr.toString());

})(current, parent);

If my response helped please mark it correct and close the thread so that it benefits future readers.
