SLA based on Transfer Order DFF or Destination type or Destination location.

Summary:

Hi Team – We are using SCFO for transfer order shipment to generate interco AP/AR invoices. When we do shipment from source org, below entries get generated:

Inventory Valuation – CR
Interco COGS – DR

Destination type of the Transfer order is "Expense"

We have a requirement of deriving SLA for “Interco COGS” depending on Transfer order type. We approached with two ways to identify Transfer order type:

1) Transfer order header/line DFF
2) Transfer order Destination location.

We designed a description rule for below attributes of Transfer order to see what values we can use in source (in Mapping set) but these sources are coming blank and hence we are not able to derive SLA based on below sources. Anyone has worked on deriving SLA account based on transfer order attributes? Please help.
