OK Here goes an question that I hope makes sense.

The small POS that i am working on is progressing however, I have just noticed an issue with a popover portal display that i am not sure is correct or how to work around it. I will try and explain.

If I create a new transaction record and dont put any data into the portal where the dummy product is 

In the image 

i.e. it is blank then when i click on the Green fruit /veg button to the right and the popover displays, i get a blank portal display.

whereby i am looking to get 

When the popover displays. The popover is 7 portals side by side to form a grid. It works absolutely fine if a product has been entered into the left hand side eg where the dummy product is. It then displays. I tried to enter the dummy at new transaction via script and then delete it in the same script but the popover is again  blank. The popover portal is based on a seperate table to the portal where purchases are entered.

Any clues as to what i might be missing. This is in FM15ADV. on windows 10.

Sounds like you're showing related data but when the parent record is empty there's nothing to relate to.
