I have an app with purchases and sales. When i create sales order, i can see order details and click to add. See picture 1. However the same thing i cannot do for purchase orders. See picture 2. I checked columns etc. they have the same set up. Details in both table are List column type and connected with Ref_Rows function. After saving header info for purchases, i can see add function. see picture 3.
Anyone can suggest what to do?
