Work Order is not closing even after work order tasks are closed

[Pranav28]

The work order has multiple work order tasks.
When all the tasks are closed, even then work order is not changing state to closed complete?
What could be the reason?
We checked all related BRs and flows, but unable to find anything.

Also, found one thing on product documentation regarding configuration of Request driven vs Task driven. But they said, it's available in Facilities Management but the plugin is deprecated. Where can I find these configurations?

If there isn't any code of flow that handles this, than that's the reason your WO's aren't closing on the closing of the task(s). You will need to create that yourself.

Hello Mark,
If there is only one task, then, WO is getting closed BUT if there are multiple work order taks, then only this problem is occurring. Any idea on this scenario?

You need to check on the closing logic. Do you have flows behind this? Are different tasks handled in a different way? Your logic could be 'on closure of task, check if any other tasks are open and if not, close wo', but there is other logic in place on your instance. We don't have access to your instance, so it's only guess work.
