How to create an index report from a large report with BI PUBLISHER.

  My need is to create an index report that will provide the specific information:

customerid and the PAGE NUMBER that this customer exists on my large report.

With reports builder you could achieve this by creating a format trigger,
and call SRW.GET_PAGE_NUM (page_num).

Do you have any suggestions on how we could do this with
BI PUBLISHER ?

Thanks
