I have also installed the Wireless Warehouse application. I like the “Outbound Orders” menu where you can process picking transactions (STK-SHP for stock order or PUR-SHP for BTO order).
By any chance, did you find out how to ship a MTO order? When the last operation of a job is completed, no transaction is generated for us to process with the shipping. I don’t even understand how to add lines to a manually created packing-slip.
For stock and BTO orders, the “Picked Orders” menu works well for automatically generating the packing-slip with a line.
