• Group selection formulas.
• Running totals.
• Calculation of formulas marked "WhilePrinting Records."
These are formulas that contain references to subtotals or summary
information, also known as "PrintTime" formulas. This evaluation time is
known as "WhilePrinting Records."
• Cross-Tabs, charts, and maps.
Cross-Tabs, charts, and maps that include running totals and/or PrintTime
formulas, and charts that are based on Cross-Tabs are generated in Pass
2.
• OLAP grids.
• Subreports.
• Generation of Pages on Demand.
Note:
• Subtotals, grand totals, and summaries may appear to be incorrect if the
report has a group selection formula. This occurs because the grand
totals and summaries are calculated during Pass 1, but the group selection
formula filters the data again in Pass 2. Running total fields can be used
instead of summaries to total data in reports with a group selection
formula.
• You can use on-demand subreports to ensure that your main report
remains a single-pass report. With on-demand subreports, Crystal Reports
must still make a second pass through the data; however, this second
pass does not begin until you drill down on the subreport. Consequently,
you can increase the performance of reports that contain subreports by
using on-demand subreports.
Pass 3
In the third, and final pass, the total page count is determined. This applies
to reports that use the total page count, or Page N of M special fields.
