In the Sales Order Document Form, I have created a tabular section named "Delivery Term", which includes a field called Product. I would like this product field to pull data from the Product field in the Product tab. For example, in Delivery Term in screenshoot (1.2), when selecting a product, only 2 specific products (shown in the image) "Keyboard A4Tech" and "HP Laser Jet Pro MFP M426fdn" should appear. Please refer to the attached screenshots 1.1 and 1.2 for reference.
I would try to use the "OnChange" procedure and fill in the table you added with data on delivery times there.
Can you explain what code to fill in OnChange? For example, in Delivery Term, when selecting a product, only 2 specific products (shown in the image) "Keyboard A4Tech" and "HP Laser Jet Pro MFP M426fdn" should appear (take from Product in tab Product).
