The Sub Vendor tab on the Contract Revision (CMR) transaction allows you to modify sub vendors or sub contractors associated with the procurement. Commodity lines are not linked to the sub vendors. This section does not contain any required fields to submit the CMR 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 or if a new Sub Vendor line is required on the CT Sub Vendor line, and then this tab would be used on CMR to add new lines to CT Modification. The same logic applied to the CT transaction is triggered to this tab (if populated) on validate of CMR. Refer to the "CT's Sub Vendor" topic for validation logic for more information.
