Master data maintenance for two plants

Question

Dear All,
there are two plants having same materials on both plants. sohow can we maintain aster data for both plants,
should we create MICs for both plants,
and inspection plan for both plants

Answer 1

But you are then making the same product using 4 different methods!  That is terrible from a quality perspective.  If I'm a customer I don't want to have to worry about what plant made it.  It totally goes against having standard specs.  Quality should be consistent across plants.  You can manufacture it however you want, but the quality control, i.e. the tests and specs used must all be the same across all plants.  Its one of the reasons SAP is designed the way it is.  (One exception may be if a country requires a specific test for a product that other countries don't.)
As far as changing specs and adding/deleting characteristics, those aren't things that should be changing very much.  Testing and specs should be pretty static data once it is created.  Coordinating changes shouldn't be that difficult.  Even when using separate plans you still need interplant coordination. The last thing you want is to wind up with 4 different specs being used across 4 different plants.
It also means anything like COA's or certificates have to be managed much differently with a much higher level of maintenance.  Using any features of batch management are almost totally wiped out.   You could maintain separate plans and utilize the same MIC's however and use batch management.  But using separate MICS would really hurt the usage of batch classification.  Comparing quality between plants becomes much, much harder.  Reports can't be consistent.
My biggest objection is not that you would want to do this. I can understand that there may be a unique sitiation out there that requires separate plans and maybe separate MICS as well.   But you told the poster that it was required to use separate inspection plans at different plants.
I know not everyone sees and knows everything about everything.  I certainly don't and I've made mistakes.  But if we are going to post advice and solutions, we need to try and make sure it's correct information.
