Troubleshooting: System did not prompt UOM conversion alert when create Invoice using item package

Question: When I create invoice with Item Package, system did not prompt UOM conversion alert although the item in the package is in back order level. Why?

Version: 1.8 / 1.9 / 2.0

Possible Reason :

You did not enable the function to check back order quantity for Item Package.

Solution :

1) Go to Tools > Options > Stock > General Stock Setting, check the checkbox of “Check Back Order Qty In Item Package” , and click on OK.

2) Edit your existing invoice I-000035 by click on “-” to remove the item package, then add back the item package. The system will prompt to alert the item is in back order quantity, do you want to do UOM conversion for those items. Click on Yes, and the UOM conversion document is created.
