PO recommendations generating with Purchasing UOM, but requirement is to have recommendatins in item

Hi Sir,

In the current instance Items are created with primary unit of measure as Retail and purchasing UOM for all items is Case. Now when ASCP is sending the PO recommendations, I see the requisitions are created having Case UOM(i.e Purchasing UOM).

But in earlier instance I used to get PO recommendations in Retails(i.e in Primary UOM).

I checked the setups of both the instance and I am not able to find any difference. Therefore please suggest why ASCP is sending PO recommendations in Purchasing UOM i.e in Case. But the requirement is to have recommendations in Retails UOM(i.e primary UOM).
