Exit or BADI after activation of the Contract module RE-FX.

Hi

I need to automate the creation of a contract in MM module after to create the contract in the RE-FX. I thought in to create a EXIT or BAPI that execute after Contract Active.

Has anyone done this?

Example: In my scenario I have a service contract created in RE-FX for control of the property, but also needs to be created a contract in MM module so I can accomplish the measurement of service delivery. In this case I have a contract in MM, a purchase order and after that, a service.

Tks.
