Architects prevents deletion if the item is a flow used by another flow or prompt. You cannot delete an item if it is a resource dependency for another item. For example, let’s assume Flow A includes a transfer to Flow B. If a flow author tries to delete Flow B, Architect returns an error message and fails the deletion attempt.
If you encounter a deletion error, perform a dependency search on the resource to determine if it is associated with another item. Remove the dependencies (in the example above, remove the Transfer to Flow B action from Flow A), and then delete the resource.
