Crystal Report Page header suppress issue

I need to suppress the page header when there are no records in the detail section.I have used

onLastRecord

at page header->section expert->suppress.it works fine but issue i开发者_运维问答s when there is only one record in the detail section.then page header is suppress how can i avoid this?

I think your question requires more detail.

Anyway, based on what I have understood, I would suggest any of these ways to sort out this issue.

1. Add a count() function formula to the suppress section. Find details here.

2. Add a condition like OnLastRecord or {GROUP FIELD NAME} <> Next({GROUP FIELD NAME}). Find details here.

3. Check for IsNull({table.field}) of a non-null field.

4. Check whether the DisctinctCount of the PK field is null.
