Vendor creation allowing with wrong Pur.Org. and wrong Company Code

Dear Experts,

In our company we have Company code A having the purchase organization B and purchase group X, plant 1

Another company code B having purchase organization C and purchase group Y, plant 2

When I am creating the vendor master in company code A with purchase organization C and purchase group Y, system allowing to create the vendor master with out any error message.

why system allowing this, because company code A assigned the purchase organisation B and purchase group X.

Is there any setting required to stop the at the time of vendor master creation.

Regards
