THERE SHOULD BE A WAY TO FIND BARCODE WHICH ARE INCLUDED OR EXCLUDED IN ANY ASSORTMENT.
THERE IS AN OPTION TO SHOW ITEMS BUT IT WORKS ONLY FOR INCLUDED ITEMS NOT FOR EXCLUDED ITEMS. ALSO YOU CAN ONLY SEARCH THE BARCODE AND NOTHING ELSE LIKE THE I CODE OR ITEM NAME OR ANY OF THAT SORT.
Present architecture does't allow us to display both include & exclude items. But as a workaround you can use the 'Show Assortment Details' option in Allocate Incentive module. There system opens the original assortment window in edit mode having both include & exclude groups.
We're marking this unlikely to implement. Appreciate your effort. Keep posting your idea.
