Testcase to check if the performance of purchase inout jasper was improved.

1. Select / create a purchase inout for G000X with a lot of lines, that still has at least 1 orderline open in Wareneingang POS

2. Select the line in Wareneingang POS, and click Drucken Produktanlieferung:
   • => jasper for purchase inout opens, without much waiting (~1-1 sec.)
3. Open window Wareneingang, search for one of your inoutlines, and do print preview:
   • => jasper for purchase inout opens, without much waiting (~1-1 sec.)
4. Get the queries (old & new one) for retrieving the inout jasper, run them on db:
