Vendor is not defined in Company code

I created a vendor and a new material.

For that material from the above vendor i created a PO and received. Now i am trying to create an invoice. It is giving the following error:

No master record was created in company code "3000" for vendor number "SUPER".

The systen gave the Solution as

"Maintain the vendor master record "SUPER" in company code "3000" or correct the account number."

Can anyone please tell me how can i do this ?

Thanks in advance.
