Mass update of Third Party Vendor at PO Line item pricing condition

Hi All,

We have requirement from business as follows:

We are using item level condition for Lumper Charge in PO and it is for Third Party Vendor. We maintain vendor in pricing condition record so it will be automatically populated while PO is created. Recently vendor is changed so we have also updated new vendor in pricing condition record so it will be taken care when new POs will be created. But there are thousand open POs in which new vendor needs to be updated.

Is there any way to mass update third party vendor at PO line item level?

Relevant pointers will be rewarded.

Regards,

Tt
