Replenishment in SAP Retail - Article with multiple UOM/EAN

Dear all,

I am using SAP Retail. I have an article with multiple unit of measurement as well as multiple EAN. A good example of this article will be canned soft drinks. It comes in pack size of each, 6, 12, 24. I have only one article number for this soft drink but I maintained multiple UOM and EAN for this article.

When I run auto-replenishment, I can only run it based on one of the packed size (fixed it as the default ordering unit).
