Maybe someone has made an app to register new Goods Receipts: choose supplier, then scan item barcodes, enter the qty received?
Preferably using Rest API v2.
This is not the issue of upgrade SERP. But serverip.dat in this case contains the value: 192.168.88.12:1301, so this is local IP of the server with SERP.
Anyway I don't understand what do you me...
