I have some more detailed info for this problem that may help someone find out what is happening.
I have a work order for 30 items.
10 were turned in on 1/24/07. The Item Transaction shows a cost of 65.2000 (this is good)
10 were turned in on 2/26/07. The Item Transaction shows a cost of 62.7370 (this also looks good)
Now we want to turn in the final 10. We answered Yes to this is the final receipt.
This is what the WO-I screen looks like:
Why is it calculating an actual Unit Cost of -4.7903 ?
I calculate:
(10 * $65.2000) + (10 * $62.7370) = $1279.37 - - Turned in before
$1884.50 - $1279.37 = $605.13 - - Dollars yet to turn in
$605.13 / 10 = $60.5130 - - Actual cost per item
Someone please correct me so that I can understand were this Unit Cost comes from.
