redwood self-service procurement charge account

Redwood self-service procurement charge account is not being derived even if the mapping sets are working (in the old UI).

Here I have done the requisition preference to reflect the project number

But it is not getting picked up by the requisition lines and even if I fill up the project details manually for the requisition line charge account is still not getting built.

Do I need to be opt-in to a service or ran something to have the charge account mappings triggered in redwood self-service procurement?
