Interrupt operation in planning board

Hi,

We are doing the interruption of an operation to rescheule the order.

After doing the final confirmation of the operation also the interrpted operation is not getting moved from the planning board but the remaining orders are moved while doing final confirmation.What is the process of removing the interrupted operation from planning board?

While doing interruption should we do for the particular operation or for the entire process order.

Thanks,

Prash
