Report Designer Reference Manual

You can also use the "Pagebreak Condition" property and the RemainingTableSpace() function to create a page break if not all records in this group fit on the current page. The function returns the available space, if you set the 2nd parameter to "True", this value will be delivered in 1/1000mm. If you now want to specify that a page break is to take place if less than 3cm space is available before the data line is output, enter the formula 'RemainingTableSpace(True)<30000' for the property "Pagebreak Condition".
