Production Order Routing

Lamba

Hi,
When we Create Production Order from a Sales Order, status -> Firm planned.
Then on the production order the Routing Lines are copied to the production order Routing.

I want to know the codeunit which writes those lines as per the production order.

i tried:
1. Code Coverage..there were many codeunits..but couldn't find the one which inserts the Routing lines.
2. Tried putting messages,,but couldn't reach that point where it inserts the Routing lines.

Please help
