Create Contract with reference to PO

Hi

Once the vendor has been selected based on the quotations the user will create PO. If the value of the PO is more than 10000 then the contract or agreement (with terms and conditions) will be prepared and send to the vendor. For each PO they want to create a contract. This contract won't be used to create another POs.

Can you please share your ideas to fulfill the below requirement.

Regards

Harris
