PPMs in APO

149 Views

Hi,

I have a basic question with regard to PPM.I have 2 workcenters A and B in which i can process the same product. Following are the possibilities in R/3 and APO.

1. I have defined workcenter B as alternative to A using classification system. I have defined the Routing in R/3 with workcenter A and transferred to this APO. Now i have PPM for this material with two modes A and B.

2. I defined the Routing with Workcenter A and maintained alternative sequence with work center B.When i transfer this Routing to APO, system creates a PPM with alternative modes A and B.

3. I have defined Routing with two group counters with different base quantities. one group counter with with workcenter A and another group counter with workcenter B . When i transfer these (these are two production versions), it creates 2 PPMs in APO.

What is the difference between 3 and above(1&2).

When we run the MRP Heuristics in PPDS with finite planning,system will check the alternative resources also,if the primary resouce is not having capacity. Similarly the system should check alternative PPM2(resource B) also if PPM1 (Resource A)has no capacity.

I believe we define 3rd case if the processing of the base qty ( and if lot sizes also different) is different in different work centers.That is 200,000Kgs qty can me machined in 24 hours in Workcenter A and 350,000Kgs qty can be processed in work center B. Is it correct?

Please comment.

Thanks
