Use the same cost code, it just goes to a certain phase.

Hi Lela, Are you treating the fabrication locations as vendors (even if they are your own)? On the set up of ost codes, it seems like a good way to separate and track the process, but one other consideration for making an expanded cost code list, is the added difficulty on the accounting side to code properly, correctly, because of the expansive list. We can talk more on this when we discuss the reports we are going to work on. Jim

I would bring the materials into inventory to separate locations.  Then allocate the raw materials into fabricated products.  Then allocate the fabricated products to the job.  I would not do separate cost codes for locations.  

You should know that "phases" in the field usually means different segments in time.  In Sage it means breaking up the larger job into smaller jobs.  So you could just do the phases as your locations, rather than the time lines.  In your PO's you can schedule the delivery over time, or use a Master PO for the entire purchase (per location) and then issue mini PO's to order the product over time.
