RESERVE command alternative in ABAP report

We have a requirement to print article pricing data on a report (simple list, not ALV or SAP Script). If data for the next article does not fit on the remaining lines of the current page then a new page should be started. I know we can use the RESERVE command but this means working out how many lines the next article will use. Is there anything like the PROTECT/END PROTECT command used in SAP Script that we can use in the ABAP report? Or can anyone suggest another way?
