Enhancement for CM25

Hello Gurus,

I have a requirements that I'm stucked on.

Basilcally, we are working on developing a custom enhancement to enable us to run our production orders in line with our capacity. Today,we are basically promising customer orders before generating their schedule and capacity loading. We need to be to able to group, sequence and capacity constrain the planned orders, then promise/repromise the customer orders that are being generated by MRP.

I tried to look for a UserExits for CM25 but there was non. Does anybody knows any enhancement to use on these or if someone has actually done this kind of enhancement for the companies.

Rewards will be giving for helpful answers

Thanks again.
