I noticed this problem before but have always managed to work around it. Today I'm stuck.
I have a report that has two break fields, client and date. The body part displays two fields, both may contain long sections of text, many paragraphs.
I've created a subsummary report with two subsummary parts and a very long body part to accomodate the two long text fields. Both fields are set to slide up and to reduce the size of the enclosing part. All parts are set to break across page boundaries.
When I sort by client alone sliding and printing works nicely. All text slides up to use the available space on the page.
When I sort by date each date begins on a new page. "page break before each occurrence" is not turned on.
When I sort by client and date, I see the same behaviour as for the date sort, there is a page break before each date.
If I reduce the size of the body part to be approx a third of the page height I see that the subsummary part is often pushed onto the next page.
I created new layouts and the problem persists.
all suggestions welcome.
