Hi @MGainer
My understanding is that ISC automatically attempts to retry failed provisioning/deprovisioning actions if you’ve configured provisioning retries for the source(s). This is configured per source by configuring retryableErrors under the connectorAttribute. Check this post for more details on How to Configure Retries for Connector Aggregations and Provisioning Actions
Check this documentation regarding Lifecycle State Provisioning Retries
Also, you can see Natalia’s reply (Q-7) regarding failed deprovisioning.
I hope this would help.
