Good day, Experts
I am currently building an external application to insert Point of sales transaction with multiple line level, but when i try to insert multiple items using loop the result ended up with the last item inserted to the POS Workcenter. for example: i have one POS transaction that has 3 item line level when i post it only the 3rd item gets posted. how can i insert 3 different line item level in a single POS transaction without overriding the previous line?
please see the attached file for the codes in retrieving the item line levels and creating string writer
