supplier master for different company

Hi All,

We have 2 company with different base currency.

Parent company is 11000 with base currency = IDR.

Child company is 15000 with base currency = USD.

Can we use the same supplier code when input purchase order?

For example :

Supplier                Default Code               A/B Amount Code

A                          blank                                  IDR

Is it OK when company 15000 making purchase order with supplier code = A?

Or is there any impact with their transaction data?

Do we have to separate the supplier master since they have different base currency?

BR,

Kinan
