We are having this problem repeatedly. We are current on updates and patches.
 
We issue a PO with 0 unit cost.  
PO is edited when we know correct cost.  
We receive in PO-C.  
We get error in GL 0,  last transactions are out of balance and cannot be posted.  
Print a GL out of Balance report.  
It shows the debit amount to the item received is always very inflated, but the credit amount to RNI is correct, causing the GL to be out of balance.
 
In IN-A, the last cost is correct, in transactions the amount recieved to WIP is the total inflated amount.  The cost of part was .19 and we received in 200 pcs. the trans button shows 200 pcs to WIP for $10.565 cost. The out of balance report shows item debited for $2113.00 (which is 200 X 10.565).  PO button in IN-A shows 200 recd at .19 cents.
 
To fix...we change the debit amount in GL-P and post, then adjust the job with a neg misc cost to reflect the overcharge.
 
Any help with this would be greatly appreciated.
