The value of the "Pass Setting" property in the R:BASE Report Designer determines how many times a report traverses the data before generating pages.
The following two options are provided:
One Pass: The report generates the requested pages during the first traversal of the data.
Two Pass: In the first pass the report traverses the data, calculating pagination. Then in the second pass the report returns to the beginning of the data and traverses the data again generating the requested pages.
Two Pass setting is important when displaying summary calculations in Report Header band, summary calculations in the Page Header band, and Break Footer calculations in the Break Header band.
Anytime you use a System Variable like "Page Set Desc", the Pass Setting will be defaulted to Two Pass so that the variable will calculate correctly, and much faster. Please be aware of your current Pass Setting and its effect on calculations. This dual pass allows for summary totals to be displayed in the Report Header, Page Header bands or "Report Cover Page" prior to printing the data.
Notes:
•The "Look Ahead" property for DB Calc (Count, Sum, Minimum, Maximum, Average) variable should be set to True.
