Hi,

I want to use top-of-page event in an alv report.I want to display the following text at the top of the page before the data gets displayed in the alv grid.

Title: purchased parts forecast report

Currency: USD

Period: 01.10.2007 To 31.12.2007

Sys Date and Time: 24.10.2007 20:01:57

How can I do this in an alv report?
