Hi,

I have purchase order, PO send material to subcontractor for machining. No further in house process. Material in Meter and item in pieces.

The setting is material stock is transferred to subcontractor warehouse when generating PO. Then issue from subcontractor warehouse to this PO when warehouse receipt.

View this PO in integration transactions :

1. IDT 10001052 for PO/Issue (Material issue in meter to this PO)
Material cost is 8.19m * 18.6708 = 152.91
2. IDT 10001074 for PO/Receipt (complete item receive from subcontractor)
Item cost is 252pcs * 0.54 = 136.08
3. IDT 10001091 for PO/subcontracting WIP (???)
Cost is 8.19m * 16.9365 = 138.71
where 16.9365 is cost in item - costing, ticpr007
4. Item lot price per piece is calculated based on No 2 and No 3 (why ?)
= (136.08 + 138.71) / 252pcs = 1.0904
5.
My question is
1. Why system is getting standard cost in No 3 for calculation ?
2. Why Item lot price per piece is not (No 1 + No 2) / 252pcs ?
3. If PO is closed, system will generate 2 more pairs of transactions
IDT 10001030 for PO/Efficiency Variance
IDT 10001071 for PO/Purchase price variance

Anyone has idea to eliminate IDT 10001091. Thanks from Cindy
