Getting repeated header on same page with different numbers in oracle RTF

Summary

I have a data model G1 which have header information of invoice & G2 which have line information of that invoice.

Content

I am using start & body tag as i want some content in header & footer part. But i have a repeating group as well as i need to print multiple invoices also with single invoice on single page.

Using for each tag before start for G1 causing repeated headers on single page.

Please suggest a solution on this.
