When one of the Purchase requisition lines are rejected and if the option "convert all lines (except rejected)" is checked, the system converts all approved lines to PO.

Is there a way to change the status of rejected line to "submitted" or "modified"?

Thanks

When the requisition is approved or or already converted the lines can not be modified anymore. So also the rejected line can not be changed.
When the requisition is submitted then use session 'Approve requisition'. In that session there is a lines button. In that way the lines can be modified.
