Purchase order gets auto rejected when copying/adding a new line from process requisitions

We are trying to create a purchase order from process requisitions using an existing requisition .

The document will already have a line associated with it and we will add a new line by copying/by manually creating

After submitting for approval , This will be auto rejected due to the rule it triggers.

Below is the rule configured

Our requirement is

when a document is being added with new line , It should go to cost center manager for approval and when a new line is not added it should auto approve

Is it possible ? If yes what condition can be used
