Lanham EDI 856/ASN for a "DC-Multi Order Shipment" where one of the order loop must include at least 2 Pack/Tare levels

My ASN has S-O-P-I-O-P-I where there are actually several 'I’tems. I think that they are looking for S-O-P-I-O-P-I-P-I. I don’t understand if I have a mapping problem, a packing rule problem, or a process problem.
