Cancel an item on a Material Request with other items

Is that possible? Cancel, Amend?

The tracking still working? I mean… MR00001 will be canceled, but MR00001-1 keep the tracking data, of PO, PR… ?

I do not think this is delivered functionality available in ERPNext.

Thanks for your answer… But… If the material planner made a mistake… It Will be opened forever??

Thanks!!
