I have a question about how to run a data-driven test in the below case. Can you take a look and recommend how can I do it?
I want to create multiple Sales Orders with an optional number of line items.
For example, 2 Sales Orders with header and Item like this
***Header:
Number txtSoldToParty txtShipToParty txtPONumber
1 1000000 1000000 Test001
2 1000000 1000000 Test002
***Item:
Number txtMaterial txtOrderQuantity txtUnit
1 7641 1 CS
1 228.911 1 CS
1 1022.911 1 CS
2 7641 1 CS
2 228.911 1 CS
The UI to configure like the below image

My current Test Suite:

How can I set up the test scripts to solve that problem? Could you guys please give me some recommendations?
Many thanks
