Note: I received these questions via a SR and I’m posting them in the community so others can benefit from the answers.

Question A:

How are sorted the demand lines in a Packing Slip when using the Order and Ord/ShipID options?

Question B:

When generating the Packing Slip using the Ord/ShipID option, why there are fewer lines than the lines of corresponding Material Stock Request (MSR)?

Question C:

The INS6500 Packing Slip report is also sorted by SHIP_CUST_NAME2 field (PS_IN_DEMAND table).

From where is the SHIP_CUST_NAME2 field coming from?

Question

In case of a MSR generated by the Par Replenishment process, the INS6500 Packing Slip report includes a page break for one of the items, generated by a blank value in the corresponding field SHIP_CUST_NAME2 for that Item, from PS_IN_DEMAND table.
