Multiple SKUs in Packing Determination - AFS Packing

Dear Gurus

I am trying to pack AFS materials in Delivery. We have assortment packing where SKUs of different materials are packed into a single carton. I am maintaining both the materials in a single packing instruction.

And while maintaining the Packing Determination records, I am choosing more than 1 SKU. But in the delivery the SKUs of a single material are getting splitted into two cartons and each carton is having only one SKU of a material where as the requirement is all the skus of both the materials are to be packed in the same carton.

Please reply.

Regards,
