Modeling

Hi All,

I have the following requirement:

Plant customer code

1 c1 M1

1 c2 M2

1 c2 M3

1 c2 M4

1 c2 M5

2 c1 M6

2 c2 M7

2 c3 M8

2 c3 M9

i get only the code from the transaction data i need to model that, so how do i go by modeling, I already have the master data for plant and customer, does it help if I make the code as nav. Attribute for plant and make it cust specific but a particulat cust may have many codes for one plant.
