Corrupted sales order
I have a sales order created by VA01, but some how there is a schedule line with no sales order item (really don't know how to produce this error...). i.e. we have sales order item 00010, 00020, 00040, but with schedule line 00010 001, 00020 001, 00030 001. So when i open the sales order again, either by VA02, VA03, error "Item does not match schedule line (program error)" prompted. I find no way to delete this sales order. Any one has encountered such problem before? Please kindly suggest how can I fix it (either change the sales order or delete it). Thanks!
