Filtering data
The Attach to Apama dialog allows you to define a filter, which specifies a condition on rows of a data table. Only rows that satisfy the condition are included in the table that serves as the value of the attached property. See Using the Attach to Apama dialog for details on specifying filter conditions.
Filters are used frequently in dashboards. Most frequently they are used to select a single scenario instance or DataView item for which dashboard objects are to display
Note: When you create an attachment to an instance or item table, constraint table, or correlator status table, the filter identifies the rows in the table you want to use. When you create an attachment to a trend or OHLC table, the filter identifies the table to use.
