Re: how to use copy default values for material from vendor master in Account Group

Dear Jurgen:

I have made the field in account group for blank,then create a PIR,the value in vendor master data for purchasing group,planned delivery time still can be copy to PIR automaticly.Should we do any other settings? 

And my another questions is:  I can understand the section value copy to PIR,but when do the value copy to material master data?

Thanks!
