MDG Purchasing organization

Hi,

I havea problem when create a new supplier in MDG 7.  I 've created a new supplier with fuction BBP000 and a company code, but when I added purchasing organizations, to display the error missage:

Fill vendor number, personnel number, or contact person number

The company code and purchasing organizations are well related. I tried to create the change request selected other fuctions (FLNV01 or FLNV00), but the message appear.

Thanks!
