As advised previously, MDI had to create Thong Thai as a local usage supplier with a remark that Regina is the specific supplier. The pricing structure is different for Regina produced garments vs other T1 produced garments. In other words, your final costing will not be accurate if Regina is chosen as the supplier.
You must have Thong Thai as the chosen supplier in the BOM for the costing to roll up properly. Pls confirm understanding.
