We have two projects, one for Capital Expenditure (CapEx) and one for Operations (Ops). The Project Task code is different for each. Approver A could be in both CapEx and Ops hierarchies. However, we'd like PO for CapEx task to be routed to the CapEx hierarchy and PO for Ops project routed to the Ops hierarchy based on the Project Task. Is this possible only through customisation?
