Production Plannning: Work Centers

Our SAP Implentation Consultants are creating work centres in Production Planning which are different to the workcentres in Plant Maintenance as follows.

Work Centres in PP

Mixing
Blowing
Filling
Packaging

Work Centres in PM

Mechanical
Electronics
Electrical

My observation is that in PM the work centres should be identical to PP work centres. whereas Mechanical, Electronics and Electrical should be configured as divisions or departments. The idea is that by having PM WC identical to PP WC the costing will be simplified.

looking forward to expert's advices, please
