Min-max requisitions not grouped with manual requisitions while converting POs.

Separate purchase orders are getting created for min-max and requisitions created manually from catalog.

Same supplier, site, buyer, ship to org and location on both requisitions (same agreement reference, same item). 

Do requisitions with different import sources not get grouped into a single purchase order?
