R11 Sub Retainage - Project Costing & Revenue with Auto Bill Holds

We are on R11 and, because it appears full retainage functionality doesn’t appear until
R12, we are trying to create a manual retainage solution.

As part of this R11 effort, as well as any retainage solution we create in R12 once
re-implemented, we need expenditures related to retainage, which on R11 we plan to
separate from other expenditures as separate expenditure items but with the
same expenditure types, as part of separate unpaid but costed retainage vouchers against POs, to
be costed and receive revenue, but without billing our client until the
subcontractor retainage invoice is paid later.

We want to avoid having to manually place these expenditures on billing hold before
