Will deleting SC line item automatically delete PO line item?

Hi Experts,

We have a shopping cart with 4 line items of we have deleted 2 line items.

We expect the same two line items in the PO will also get deleted. But it is not happening. Instead only one line item is deleted.

Either both line items should not be deleted or both should be deleted. It is mysterious that only one line item is deleted in PO whereas 2 are deleted in SC.

We are using a Classic Scenario.

Kindly throw some light on the issue.

Thanks,
