Landed Cost and Receipt Routing

What is the best way to do landed cost with receipt routing?

Unfortunately, we cannot do Standalone as the number of receipt lines are high and there are too many cost levels in our landed cost.

The nearest matched procedure to our requirement is to display the landed cost screen so that the inventory user can revise the supplier of few cost levels. But this is not possible if we activate the receipt routing.

The only option is:

Do Blind Landed Cost during Receipt Routing.

Reverse the receipt lines if the supplier is different than specified in the default rule.
