Can’t access suborder for vendor user

Hi Team,
kindly help us
We are using multi order for woocommerce plugin for splitting orders. Also we have vendors for selling products. Also we have options for cancelling & refunding product. While ordering a bulk no. of products in an order, that orders are not accessible as child orders in vendor dashboard. So if a user cancel a sub order, the vendor will not get that information as the product is cancelled. So please help us for getting suborders in vendor dashboard.
