How to make INCIAR (Intercompany AR Invoice) honor Price Break in price list for Intercompany Drop S

Dear Experts,

End user's company using Intercompany Transaction Flow with two models:

1 - Internal Requisition > Internal Sales Order

2 - Drop Ship Sales Order

Now they already followed note 'INCIAR Create Intercompany AR Invoice - Pricelist, transfer price, pricebreak related issue (Doc ID 748566.1)' completed setup.

Find for Internal Requisition > Internal Sales Order flow, INCIAR (Creat Intercompany AR Invoice) is able to retrieve price from Price Break setup in Internal Price List successfully.

But for Drop Ship Sales Order, INCIAR (Creat Intercompany AR Invoice) is NOT able to retrieve price from Price Break setup in Internal Price List, but from Sales Order Line price.
