The Vendor tab on the Master Agreement Revision (MMR) transaction allows you to modify the Primary and Secondary Vendors for providing the goods/services. Vendors are selected from a pick list that is populated by the Vendor/Customer table. This tab does not contain any required fields to submit the MMR transaction to Final. You should only enter values in the fields in the column on the right if a change is needed to the existing value shown in the column on the left. For additional information, refer to the MA - Vendor topic.
