How to use integer dataitem in RTC report

I have created a simple report with integer, sales invoice header, sales invoice line.

sales invoice header is indented to integer
sales invoice line is indented to sales invoice header.

- Integer
- Sales Invoice Header
- Sales Invoice Line


I have written code to print the same 1 page report to 3 pages(1st page as Original, 2nd page as Duplicate, 3rd page Triplicate) by using integer.

On PreDataItem()


intNoOfLoops += 1;
SETRANGE(Number,1,3);

onAfterGetRecord()


IF Number=1 THEN BEGIN
txtCopy:='Original';
END;

IF Number=2 THEN BEGIN
txtCopy:='Duplicate';
END;

IF Number=3 THEN BEGIN
txtCopy:='Triplicate';
END;

This is working fine in classic but it is not working in RTC report.

Do i need to write any code in RTC.

Can anybody help me in this.

Thanks,
Pradeep
