We're starting to use projects more and more and the question has come up: what is the last point at which we can assign a WBS element to an object like a Supplier Invoice, or a Purchase Order before having to completely cancel/reverse and do the whole thing over again?

The concern is that if a user misses entry of the wbs element on a line but that is the only thing wrong with the supplier invoice or po that there will be a ton of work in reversals and cancellations to correct.

Thanks,

Ryan
