Symptoms

Customer/Reseller place a Change Order from Customer/Reseller CP, and the order failed with the message from Vendor.

The vendor has rejected the request for the following reasons: 
Upsizing and downsizing in the same request is not allowed. and Request under 1:1 business model can only have one item.

Cause

In Connect, the PR request is rejected, due to the fact that Vendor does not allow such changes to be placed in single Change Order.

Resolution

Please cancel Change Order and place two separate orders, instead of using one order for all changes.
