To my knowledge there isn’t. When we first implemented Epicor, We were only purchase to inventory. The only way to view what jobs the PO suggestions were for was to view it through Timephase (at least is what we were told).
That was the path we were going to go. But we convinced the higher ups to switch to Purchase direct =) Now, just to clarify, when you say job requirements, what are you meaning? You just want to know which job the PO Suggestion is for?
This also is what worked for our situation. We are more of a JIT manufacturer, so we try to keep inventory levels as low as possible. We typically have a quick turn around on any material we order. However, I do see certain advantages for other companies to use “Purchase to Inventory”.
Purchase direct will make a PO line (or release) to every material sequence. For companies with large BOM’s (say a job if for a whole machine) if you buy direct to a job for say a nut, every assembly and material sequence that nut is used, you will get a line that has to go into a PO.
Secondly, when you buy direct to a job, the average costs do not get updated, as it’s treated as a special order that will not affect costing.
