How to set Assignment Groups based on Different User's Division on REQTASK (sc_task) - Catalog Form

[AbdurRahmanSnow]

Good evening.
I have a Catalog Form, where it uses a Workflow, that is also used by 100+ Catalog Forms and creates a REQTASK. So, I don't want to do any changes in the Workflow.
Instead of it, I will use Business rule.
So, my requirement is, when someone requests the Catalog Form, based on his Division, we need to set the Assignment Group.
For example: If Requested For user is from "Global Support", then we need to set Assignment Group on REQTASK as 'Group Technology Technical Security'.

So, I am totally confused on how to create a Business rule and on which table. I tried creating it on sc_task table, have set condition as Item is "Catalog Form name", and in Advanced section, I wrote as below, but it is giving undefined, null, and lots of errors.
I don't know why current is not working. Please help me out with this. On which table should we create this BR?

Hi @AbdurRahmanSnow 

I'm not sure, but did you try the assignment lookup or data lookup at the SC_Task level? I would recommend using the flow, but if that doesn’t work, try the assignment lookup or data lookup feature and see if it works.

Hi @Dr Atul G- LNG . Thank you for your reply.
I have never heard of "Assignment lookup or Data lookup feature". Is it the below "Assignment Rules" ?

Yes @AbdurRahmanSnow 

Correct this is same.

Hello @AbdurRahmanSnow ,

Using a Business Rule for this requirement is not a maintainable and scalable solution.

You can implement this using "Assignment Rules" instead. Here is an example of routing a Catalog Task to a group based on the Department of the Requested for user on the RITM:
