Populate assignment group based on catalog item RITM by using Flow in Flow designer

[NikhilKumaK]

Hi ServiceNow Devs,

I've a requirement to populate the assignment group based on catalog item RITM, all catalog items are using same variables.
But different assignment group is used for all catalog items. There are 18 catalog items RITM mapped to different assignment group, but variables populate are common for all catalog items.
How to approach by using flow in Flow designer?

Regards,

Nikhil

@NikhilKumaK ,

What you’re describing is that you have 18 catalog items that all use the same variables, but each catalog item should go to a different assignment group. You can handle this with a single flow in Flow Designer and a decision table:

1. Create a Decision Table:

   • Condition column = Catalog Item

   • Result column = Assignment Group

   • Add 18 rows mapping each catalog item to its assignment group.

2. Flow setup:

   • Trigger: Run on Requested Item (sc_req_item) created.

   • Action: Add a Decision Table action and pass the Catalog Item from the RITM.

   • The Decision Table will return the correct Assignment Group.

   • Update Record: Use an Update Record action to set the RITM’s assignment_group field with the result from the decision table.

This way, you don’t clutter the flow with multiple branches, and if you ever need to change the mapping later, you just edit the decision table instead of editing the flow.

@NikhilKumaK 

in your flow you can check the catalog item name associated with the current RITM

Within "Update Record" on RITM you can use f(x) inline script to set it dynamically

check this and enhance

Flow Designer to set assignment group based on variable value dynamically

Hi @NikhilKumaK 

you're looking to use Flow Designer in ServiceNow to:

• Use an Update Record action on the sc_req_item (RITM) table.
• Set the Assignment Group field.
• Use an inline script to get the Assignment Group sys_id based on the Catalog Item name using a hardcoded mapping.

Please use blow script and also refer screen shot added:

 var catalogName = fd_data.trigger.request_item.cat_item.name;

    // Define mapping: catalog item name → assignment group name

    var mappings = [

        { catalog: "New Laptop Request", group: "IT Hardware Support" },

        { catalog: "VPN Access Request", group: "Network Team" },

        { catalog: "Software Installation", group: "Application Support" }

        // Add more as needed

    ];

    // Find the matching group name

    var groupName = '';

    for (var i = 0; i < mappings.length; i++) {

        if (mappings[i].catalog === catalogName) {

            groupName = mappings[i].group;

            break;

        }

    }

    // If group name found, query sys_user_group for the sys_id

    if (groupName) {

        var gr = new GlideRecord('sys_user_group');

        gr.addQuery('name', groupName);

        gr.setLimit(1);

        gr.query();

        if (gr.next()) {

            return gr.getUniqueValue(); // Return sys_id

        }

    }

    // Return empty string if no match found

    return '';
