Attempt to place renewal order for subscription fails with error:
Can not renew Subscription #XXX: There is already a Renewal Order #YYY in status New(NW). This order prohibits placing an order of Same Order Type (Per Subscription). Please either cancel conflicting order or wait while it will be processed or contact Provider.
PBA provides order number of the conflicting renewal order. A customer or Provider may find the order in PBA Control Panel and either cancel it or complete the order provisioning. After the conflict is resolved the customer can place new renewal order for his subscription.
PBA has built-in mechanism which prevents provisioning of conflicting orders, e.g. PBA does not allow to provision upgrade/downgrade order if another non-completed upgrade/downgrade order exists because it is not always clear what amount of resource must be set for a subscription by two non-completed orders.
Also, PBA does not allow to renew subscription if it already has non-completed renewal order.
