I have two Glidetables:
- List of products with started quantities;
- A management list of products that were sold with the quantities that were purchased.
I wanted the updated quantities of from the management table to my products list.
How can I do this?
Assuming that your tables look something like…
…then…
- Create a multi-relation from your Products table to your Sales table, joining
Products.SKU
to Sales.Product SKU
- Create a Rollup column that takes the Sum of Qty from that multi-relation
- Use a Math column to calculate the “Current Balance” by subtracting the result of the Rollup column from the Starting Qty

Yes, you can but one by one.
There is no a way to update multiple items (rows) at the same time. The Set Column action doesn’t support a multiple relation unfortunately yet.
But using a GS the story is different.

I think @Darren_Murphy and me are using different methods to update items 
In my case, I want to have a final amount without counting and reviewing your historical sales data.

hmm… did I misunderstand the question?
If I did, it’s because I just woke up and haven’t had my morning Milo yet.
That’s my excuse, and I’m sticking with it

Thanks to all replys.
@Darren_Murphy
How do I joing Products.SKU to Sales.Products.SKU?
I haven’t done any multirelations yet
