Grouping in RTC report

Hi All,

I am trying to convert a classic report in RTC. It has 3 table

1.Purchase Header

2.Purchase Line

3.Purch. Rcpt. Line

Purchase Line is indent below Purchase Header and Purch. Rcpt. Line indented below Purchase Line .Purchase Line is grouped on Document No. field and Purch. Rcpt. Line on Order No. field .In sections of report I have added body of both .Purchase Line as well as Purch. Rcpt. Line and related fields from both the table.

The report runs fine classic but I am not able to get the same out put in the RTC report .I can create 2 groups in RTC but can not get same result as classic which comes because of indentation.

So does any one know how to to do it ?
