Dear K.Punjira and K.Pakamon,
I have confuse in our purchase system , It may be occurred from my foolish in the normal system.
1. When user section issued PR to purchase to order some equipment , bite , tool or other with concern for support production line.
2. Purchases will contact to supplier or maker for negotiate on cost , time or any concern. If OK
3. The PO was issued and signature by requested section and top management if required.
4. User waiting for product order.
5. Company paid for cost as concern when user agree in product quality
But right now some time purchase request to user to issued cheque requisition and then transfer to supplier or maker.
That correct way to do right that. If yes, I would like to know why only QA do like that. Production never do like that (Already to confirm with production when they order bite, oil or spare parts)
If some time we can help on that. But now continuously example service cost for test our material by King Mongkut’s University of Technology Thonburi
And quality manual order to OMNEX
Your reply will fulfill my knowledge.
