On attempt to switch subscription service plan or cancel subscription an error occurs:
Communication Failure: Method 'GetResourceUsage' is not available inside a Server
In the service plan the subscription is based on there is a resource rate based on KAGATE (which does not support statistics collection) but configured to collect statistics. On performing some operation with the subscription Business Automation tries to collect usage statistics from KAGATE and fails with the aforementioned error.
- Find KAGATE-based resource rates which have the setting "Controlled By" set to "Billing" (= the system attempts to collect the resource usage statistics for these resources)
- Change "Controlled By" parameter value to "External System"
- Check if "Measurable" option is set to "No" and change if needed
- Synchronize the changes with the existing subscriptions (option "Update Prices" for resource rates is obligatory, "Install into provisioning system" can be set to "Do not install")
