Double-Pass Reports

In Database Tour Pro reports, some conditions lead to run the report in double-pass mode. This means the report formatting has two phases:

• Calculating the space required for the report and internal variables, as well as outputting the visual components.
• Calculating report expressions that require using variables calculated in the first stage.

The expressions require two formatting phases when they use the following functions:

• page_count
• All functions with StepNo parameter, in the calls of which 2 is specified as the value of this parameter.

Note: The double-pass reports may slow down large reports formatting.
