Hi,
The scenario is like: I create a sales order for a configurable material which requires to create sales order BOM. Now when I save the sales order, delivery block status and billing block status are shown as 'blocked'. Its obvious as I haven't yet created sales order BOM and run the costing for the same.
But still I am able to do the milestone billing after removing billing block from the billing plan.
Is it the standard SAP functionality or defect in the system?
