Informix Error -4356: A page header has already been specified within this report.

Cause and resolution

A page header has already been specified within this report.

Only one PAGE HEADER control block is allowed in a report. The statements in this control block must be suitable for all pages of the report (except the very first page, for which you may write a FIRST PAGE HEADER block). Find the other PAGE HEADER control blocks, and combine all their statements into one control block.
