Dear colleagues, our client is a discrete manufacturer of industrial equipment with a complex product mix which fall in to MTO / ETO philosophies. The client is currently on R3 and have a real need for doing multi level ATP.
We have explored the option to do assembly orders in R3 to do a component availability check. But assembly orders perform only one level explosion. Therefore, we are now thinking about other alternatives to do a multi level ATP check.
While the client is not very excited about APO, they might consider if APO offers real robust solution. As with so many clients, APO is not an easy affair to adopt.
So at this time, I request some implementation lessons if you have gone through addressing multilevel ATP as a business requirement
