Multi-level Bom change using ECM, conflict in application date

Hello,

We have changes in our products that are scheduled with ECM (CC01).  Our products has multi-level boms.  When we change multiple components at different levels of the receipe, the change "valid date" from CC01 seems only based on the component requirement date.

This cause some production order to have some new component and some old components at the same time, because the requirement date is not the same through all bom levels...

Is there a way to change this to make sure we're not having this conflict?

An example would be to use the validity date of ECM based on PP order creation date instead or requirement date...

Any suggestions would be appreciated!

Thanks!

Ex:

A: finish good

B component 1

C Component 2

D subassembly 1

A

     B req date 01.15.2016

     D req date 01.15.2016

          C Req date 01.10.2016

If B and C have the same change number (CC01) which is effective 01.12.2016; the production order would contain at the same time 2 recipe
