Transportation Load Number in Purchases Orders Details F4311.LDNM

Dear all,

JDE 9.2, using Transportation Management (49)

Our solution makes extensive use of Transportation Module (49) to generate Shipment numbers, and consolidate them into loads via F4960.

Not only for all customer sales orders, but also with internal transfer orders (ST/OT), and also for external purchases from external suppliers (OP)

While browsing through Purchase Order Details file, we have noticed the existence of the load number field F4311.LDNM.

However, there is no records across the whole database where this field F4311.LDNM is actually populated.

Which process / functionality makes actual use of F4311.LDNM ? Is this documented anywhere?

I browsed across the whole Transportation Management available and there is no mention of this very field.
