Hi SherLouie,
Let's see if we can answer your question here. Please do your best to provided complete details of what you're trying to accomplish, steps you are taking, and what is not working.
I note you tagged the post with Engagement Insights. Is that accurate? We have retired that product.

I'm Fairly new to CRM Dynamics 365. I'll try my best to explain it here. But here's what I'm trying to do, We already added item to products (field service). Then I created a custom tab where I then created a sub grid with the products entity as my data source for lookup. My problem is this, the subgrid will not allow me to add a multiple product of the same item. see image below

If I want to add another product name "Premium Support Service" this subgrid will now allow it.
