Unable to provision Plesk lease license through API request:
Conflicting feature set
The API request contains feature REINSTATE_SUS
Applicable to provisioning Plesk through Operations Automation Billing product with the following features: "Parallels Plesk 12 for VPS Web Admin Edition" and "Monthly SUS for Parallels Small Business Pane"
REINSTATE_SUS is no longer used in KA since January 2017 for API requests for creating lease-keys.
Remove "Monthly SUS for Parallels Small Business Pane" from a plan so that API request does not contain REINSTATE_SUS feature.
