Built-In Keys

A number of useful Data Keys are included by default.  These tables lists the keys and provides a brief summary.

Built-In Report Data Keys

Key Description 
GatewayName of the Report's Ignition Gateway
NameName of the Report
PathPath to the Report in the Project Browser
TimestampThe Gateway's current timestamp

Built-In Data Keys

DateThe current date/time
RowThe current row number (only in tables)
PageThe current page
PageMaxThe total number of pages in the generated report
PageBreakThe number of explicit page breaks encountered
PageBreakMaxThe total number of explicit page breaks in generated report
PageBreakPageThe number of pages since last explicit page break
PageBreakPageMaxThe total number of pages in current explicit page break
RowShows the current row number. Must be used in a table


The "total2" key

An aggregate calculation will result in null if any of the individual values are null (rather than return a value that is technically incorrect). You can work around this by implementing a derived method that returns a default value if the original attribute is null and aggregating using that key/method. Also, most of the aggregates contain a second version ("total2") that assume that null is equal to zero.


The "count" and "countDeep" keys

The count keys tell us how many objects are in a given list or group. This is most commonly used for tables with one or more levels of grouping. If, for instance, you have a table of Movies grouped by their studio and you add the @count@ key to the studio details, it will display the number of movies for each studio. So it might make sense to have a text field with " has released @count@ movies" (Warner Brothers has released 15 movies).


The count key only counts the next level of grouping. If you have multiple levels of grouping and want to count all the root entities use the countDeep key. Suppose you have movies grouped by their category and their studio, and want to display a top level summary. You could use: " has released @countDeep@ movies in @count@ different categories" (Warner Brothers has released 36 movies in 7 categories).


Heritage Keys (Running Totals, percentage totals)


There is an additional set of keys in the Attributes Browser which are used to access upper level groups: UpRunningRemaining. @Up.count@ would tell us how many objects are in the current level of grouping.

The text field "Row @Row@ of @Up.count@" might show "Row 1 of 5".

By doing some simple arithmetic and using the "Up" key, we can calculate a percentage total: "% Total: @revenue/"

The running key references a virtual array containing all of the objects processed thus far in a lower level grouping. This is useful to get a running total. For example, in a ledger: "Credit/Debit: @amount@ Current balance:"

The remaining key is conceptually the same, but results in a virtual array of remaining objects.For example: "Credit/Debit: @amount@ Remaining Activity:"
