My task was creating a programme, that can be used for tracking orders. This work was duplex. From one hand I had to make a surface that is for displaying pieces of information and the user is able to communicate through it. On the other hand I had to solve the problem how the relevant data would be filtered and built from the database on the back end system.
In the background I used SAP HANA in-memory database management system, but I often went on, and got information from SAP ERP system. As for the HANA, I used XSJS files, for ERP my coding language was ABAP and developed a function module in it.
I took some simplification about the states of the orders, and picked out only order creating with requested delivery date, order posting, goods issue, due date and the date on which the payment was done.
