Can I pull back multiple mod traits in one query?

Yes. In a store detail query you will need to add the column Modular Plan Desc. It's found under Item Information/Store Unique Modulars.

Another way is to pull them by Sel Store Trait. This will bring your sales results back by trait number (obviously). You will need to copy and paste all modular traits into your Send Traits filter on the Store Selection portion of the query.

Thanks for the tip. I queried using the Modular Plan Desc, but why does it show one blank Modular Plan for every item?

So if I pull "item A" it will give me sales on 8 different Modular Plan Descriptions, but there is always one row for every item showing sales that has a blank for the Modular Plan Description. Why is that?

These are sales where the stores don't have this item on their planogram. The store may have had the item on a previous planogram and still has inventory to sell through.
