How to default the Schema Group,Vendor in Purchasing while creating a Vendor.

Hi,

Please tell me the steps to default the Schema Group,Vendor in Purchasing while creating a Vendor.

I have created a Schema Groups:Vendor as "NP", Created schema grps to POrg & assigned Schema Grps to POrg.

Now I want when I create a New vendor for a account grp with selected POrg it should default Schema Gropu "NP" in the purchasing window.

Please suggest how to do this.

Regards,

Puja.
