Mapping variables from catalog item to Requested item

[SM123]

Hii All,

Created a variable named "urgency" in catalog item as type (Select box)

When submit the catalog item form with  urgency choice according the value, Requested item (sc_req_item) "urgency" field should change. How can I implement that using Business rule?

Please check below ss to know what i did so far.

Does the value of your urgency variable match the urgency value of the urgency field on the request item table?
