Share experience work with multiple planners

Hi Gurus,

Our clients requested to separate planner for each planning item category.

But in fact, I have not had any experience in it.

Do you have any document and experience when working with multiple planners in ASCP, please kindly share with me:

- will run each planner - one plan  or one plan - multiple planners

- in case of different planners, how's about MRP?

....

Thanks a lot,

H.
