Hi,

I have a purchase order having two products of some quantities. While receiving them I need to do partial reception. While doing that when I click on "Enter purchase details" button it opens up the barcode interface and straight away throws the error "Singleton Expeced". 

If I having only one product under my purchase order then it works fine and allows me to have the partial reception, but having more than one product, its not working for me. 

Let me know if any configuration is needed to do so.

Regards
