RE: Units of measure "missing"
The global_class_sopounits possible value is used in the sales order UOM of Inventory sites screen. This PV is based on the inventory class id & inventory stocking unit & Inventory Id.
For instance, You are having FT as Stock unit for an Item A. If you are going to add new UOM "CMS" and "INCH",You have to add the following records in your unit conversion screen.
Global * * CMS FT Divide 30.000000000
Global * * FT CMS Multiply 30.000000000
Global * * INCH FT Divide 12.000000000
Global * * FT INCH Multiply 12.000000000
After adding this lines in Unit conversion screen, you can see the new UOM's in your PV List of Inventory sites screen.
This may help you.
Thanks,
