Production order scheduling multilevel

Dear all,

i have the following requirment:

Production order MTO 1  PF

         Production order MTO SG

              Production order MTO SG

I know very well that in the standard system is not possible to scheduling all production order without handle the combination E-52 in the master data, but i would like to know if with the custom activity is possible to do with enhancement in the COHV during scheduling activity.

Is possible to add a new funcionaluty in COHV in order to scheduling the  production orders with the own logic :

Production order MTO 1  PF

                                            Production order MTO SG

                                                                                    Production order MTO SG

For example to schedule the first production order , after taht the new finish basic date calculated  must be the basic start date of the second production and so on.

Thanks a lot

Daniele
