I am working with CA SDM version 17, and I have noticed that the calculation of priority for urgency and impact, only applies to incidents and problems.
Is it possible to enable this option for requests?
I wait for your answer.
By design Priority Calculation is restricted to Incident and Problem records.

Not sure if this covers your scenario? If not I would suggest you log an Idea with the relevant business case for consideration.
