The Filter to Choose Deviations for RBM field is an optional parameter that enables you to filter rows from the DV data set to choose the appropriate records to subset to deviations of interest. Risk indicators will be calculated using this subset of deviations only.Note : It is necessary to use quotation marks when filtering data using values of a character variable ( DSCAT = "Significant" , for example), but no quotation marks are required for filtering by values of a numeric variable .The syntax of this filter expression follows the syntax of SAS WHERE statements . For more information about this syntax, see The SAS WHERE Expression .
