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.
