Restrict Data
The Restrict Data analysis tool narrows the return set by requiring data values to be relevant to
rules and operands. Data can be restricted by two-column comparison or single-column fixed
limits.
The Information panel displays Analytic Services Restrict Data definitions for the current
document.
Because Restrict Data is executed by Analytic Services, the network server is protected from
transmitting and the client is protected from processing large result sets.
Users can apply Restrict Data to result sets of processed queries (using the Analysis Tools right-
click menu) and of unsubmitted queries. The last step of the new document wizard enables users
to create Restrict Data definitions.
Table 106 6 Restrict Data Dialog Box
Control
Description
Select Column
Displays the Select Column dialog box, used to select a column from the current document
Operator menu
Specifies an operator: Greater than (>), Greater Than or Equal To (>=), Equal to (=), Less Than or
Equal To (<=), Less Than (<), Not Equal To (<>)
Operand menu
Specifies one of three operands:
●
A value Of—restricts data to a value or range of values
●
The Data Value of Column—displays a secondary Select Column button, used to compare two
columns
●
A Missing Value—restricts missing values
Value Text box
Specifies values for Restrict Data conditions
Note:
It is advised to use one member per dimension in filters when restrict data or retrieve top/bottom
is applied. If multiple members are selected per dimension, the application aggregates results.
Because restrict data and retrieve top/bottom are parts of Analytic Services queries, aggregation
occurs after queries are returned and may result in unexpected result sets.
