When error handling is set to rollback, does it rollback that specific microflow or all activities that were triggered?
On a webservice call in a subflow I set error handling to rollback. When my webservice fails, does it rollback this subflow only or the previous activities that have been executed in the microflow(s) from which this specific subflow was triggered (from e.g. an invoke button, action trigger, etc.).
Depends on the error handling defined on the microflow call, which calls the subflow you mentioned. If the error handling on the microflow call is "rollback" everything in the microflow and submicrofllow will be rolled back, if it's continue only database calls in the submicroflow will be rolled back.
