We made a mistake about Node SortOrder in Commerce 7.5 - this property was not reflected properly in Catalog UI. However, we have plan to make this right in Commerce 10 ( we have a solution already, but it's inevitably a breaking change).
I can't (and am not allowed to) say anything for sure, but it will happen before year end.
(Perhaps 1-2 months before that, but don't take my words for granted)
Did support for editing sort order make it into the Commerce 10 Catalog UI? I don't see a property, and dragging nodes around within the same category editing page doesn't seem reorder anything. However, updating the SortOrder column in the db and recycling the app pool does affect the order that items appear in the catalog ui. (We're on EPiServer.Commerce v10.0.1).
Commerce 10 was released a couple of months ago but it was a small breaking change release to be CMS-10 compatible. The feature I mentioned is now planned for Commerce 11, which has no ETA - but probably in the first half of 2017.
Again, this is my pure estimation.
I Have episerver commerce 9.11. We've had a request to order the products on our category pages. Looking in the CatalogNode table, there is a SortOrder column to hold sort data. In addition, there is a text field in commerce manager called SortOrder to edit this data. My preference would be to use Catalog UI to edit sort orders mostly because Commerce Manager requires an IIS reset in order for this sort change to take effect. Also, it's kind of a pain to edit this field in Commerce Manager.
My question is, do any of you know of a way to edit the SortOrder property for products in Catalog UI? When I click and drag the products in Catalog UI they don't seem to sort.
