Hello Gurus:
I've recently changed our SNP to run for all materials (not just finished goods). I have some subassemblies that go into about 400 different finished goods. In Customizing, I had "Heuristic: Nbr of Planning Iterations per Component" set at 10 and I found that it wasn't planning at the subassembly for all the finished goods' demand. I think I have to change this value to 400 for it to complete planning on all subs/finished goods. However, when I do this and run the Heuristic for my entire Model, it runs over 16 hours and never completes.
Does anyone know if this is a setup issue or a resource issue on the system? Is there something I can do to make the Heuristic run faster? I calculate pegging and Low Level Codes in a separate step prior to the Heuristic run and my settings on the Heuristic are as follows:
Location Heuristic
Take into account found components in planning run
Add products from super session chain
Source Determination = All Levels
Do Not use Temporary Low Level Codes
I do not have checked "Net Change Planning" because we are only running the Heuristic once a month to do Capacity Analysis.
We have about 30,000 materials that the heuristic is running on and planning.
Any ideas are greatly appreciated.
