Hello Tim,
I have been thoroughly examining the retrieved set of data you provided above, and here is my piece of findings.
First of all, we can not judge on reasons behind the variance since the quantity is not matched between Purchase Receipt Layers (IV10200) and Historical Inventory Trial Balance (SEE30303). The differences are huge, and therefore, an internal inventory reconciliation is a must.
Let's take the Item Number in Line (2) for instance,
| Item Number |
HITB Quantity Available |
HITB Cost |
IV Qty Available |
IV Extended Cost
|
Variance |
HITB Unit Cost |
IV Unit Cost |
| X |
2570 |
4678.7828 |
1720 |
3058.455 |
1620.328 |
1.82 |
1.78 |
In Historical Inventory Trial Balance, you have 2570 while only 1720 are available in Purchase Receipt Layer. This means, you are only able to consume the quantity available in IV10200, and the question is; what are the other remaining quantities in SEE30303 ?
I will provide you with a script to internally match the inventory tables and find out the differences. This script will match the quantities per item, per transaction, per location. I am expecting a huge data set retrieved. (Send me an e-mail and I will come back with the script)
Let me get back to the point I want to make about (Cost Variances), In order to ensure that this is related to cost adjustment, you need to calculate the cost of the remaining cost layers in purchase receipt work [ IV10200 ]. The value must be compared to the one calculated from HITB. Assuming that there is (20) piece of item (A) in inventory (which is the same in IV10200 and SEE30303), You might find out the following:
Item_Number Quantity_Available IV_10200_Extended_Cost HIT_Extended_Cost
A 20 100 110
Now if you withdraw all the quantity available of Item (A), you will have the following record in your HITB (which is a remaining cost, that is stock in inventory because it doesn't have associated quantity)
Item_Number Quantity_Available IV_10200_Extended_Cost HIT_Extended_Cost
A 0 0 10
The remaining HITB value is caused by cost adjustment documents. Of course, this is part of reconciling inventory internally, which means, ensuring that all the IV resources have the same value.I consider that Purchase Receipt Work is correct, because it records the new unit cost for all the remaining quantity once a cost adjustment record is thrown in HITB. It keeps the old cost though in filed "Adjusted Cost - ADJUNITCOST "
So far, Hope this helps
