Is it possible to start a site workflow which only exists in the root site from a site collection reusable workflow?
To be more specific, I created a site collection reusable workflow and associated it to each activity calendar list within the web application. Wherever someone creates an activity item, the workflow does an approval check and additional I want it to send a notification when the end time passes.
To send a notification when the end time passes, it is not recommended to use the “pause until” block. Therefor I created a second notification workflow in the root site and put a “start workflow” block in the site collection reusable workflow.
The notification workflow is not triggered when an activity item is created on a sub site. It only works from the root site. I think the reusable workflow tries to find the notification workflow within the current web.
It would save me a lot of time to call the notification workflow from the root site. Hopefully it is possible.
