Sign of PartTran.TranQty

I noticed that for a given part and warehouse, PUR-STK and STK-MTL transactions both mostly have positive quantities. I expected the signs to be different, like positive quantities for PUR-STK and negative for STK-MTL.

I found this archived thread on the subject. Is the information in that thread accurate? Does it exist in the database somewhere?

There a few threads in the E10 topic on the natural sign of each TranType, with respect to inventory.

And your original question is correct. The “normal” direction of trans are positive.
Issuing inventory to a job (STK-MTL) is positive and reduces QOH. A return from job is also a STK-MTL tran that reduces QOH by the tran qty. So a negative STK-MTL actually increases QOH
