I have another doubt .....
how to print header and detail layout as alternatively...
e.g

...
detail.1
...
header.2
...
detail.2
...

Well - does it have to be a header layout? You can control which layout gets printed by just sending a variable in the detail record. So I do this with some of the detail layouts - not specifically with headers, but I know I did it with detailed layouts. So you use the print expression. If you put something like (kind of layout) KOLO=1 and KOLO can be 1,2,3 or 4 based off the record you are sending. I do this with some of my reporting sessions where I might print production order on 1 record, then a planned grp order on another detail record. Just never really tried it with headers.

Change the header layout to before.field layout on the basis if that field which is changing in every detail.
