Symptoms

The following messages are shown during validation when the customer is trying to place a regular CH order to reduce licenses for NCE subscriptions. However, the order goes through (it fails later on in Connect).

You have passed the cancellation window for reducing seats for this subscription.
You are trying to reduce more licenses than allowed. Allowed 1 license and attempted 3.

The customers are able to place the downgrade order when the quantity of licenses to be reduced is more than the number of licenses that are eligible for downgrade. However, as expected, MSFT rejects the changes and the orders fails.

This lead to unnecessary failed orders and the customer has to manually cancel the order to allow the end user to place new orders.

Cause

The issue is caused due a software issue #UXUI-798.

Resolution

At this time, if you place the order by mistake, you should cancel it on Commerce side, since it will fail in Connect. 

Please reach out to your Technical Account Manager or review our release notes for a new version of UX1 with UXUI-798 issue fixed.
