Sort Order of Store Order Guide is inconsistent in MxC

When viewing the Store Order Guide in MxC (Inv & Order Setup > Maintain Order Guide), the sort order of the items is not consistent with that of MMS.

I believe that this sort order is defined in MMS (Corporate > Admin > Corporate Rule Setup), but this may not be the case!!

This has been an ongoing issue for a while, but it appears to be inconsistent between stores and vendors, i.e. it doesn't always appear to be the case.

Please review the code in between both pages and check that they are using the same Sort Order.

Note: this has come to light as we are trying to roll out the new MxC page and retire the MMS page.

"Confirm that the order that the items are displayed is consistent with that listed above, and MMS"
