Definition

In SAP NetWeaver Business Intelligence, variables are a means of parametrizing queries.

Variables can also be used in Open Analysis Interfaces using various BI-specific enhancements to the MDX syntax. In this context, variables are called SAP variables.

Note

For more information about BI-specific enhancements, see:

■       BI-Specific Enhancement: Schema Rowset SAP VARIABLES

■       BI-Specific Enhancement: MDX Syntax

Use

The open analysis interfaces provide variables as placeholders for the following objects:

Name in SAP NetWeaver Business Intelligence

Name in OLE DB for OLAP Specification

Characteristic values, hierarchy nodes, pre-calculated value sets

MEMBER_UNIQUE_NAME

Hierarchies

HIERARCHY_UNIQUE_NAME

Formula variables

Number values

Note

Variables for characteristic values, hierarchy nodes and pre-calculated value sets differ in the following ways with regard to the SAP VARIABLES schema rowset REFERENCE_HIERARCHY:

■       With characteristic variables, REFERENCE_HIERARCHY =
REFERENCE_DIMENSION.

■       With hierarchy node variables, REFERENCE_HIERARCHY is either filled with the technical name of the hierarchy or, with a variable hierarchy, it remains empty. Note: The hierarchy name must also be specified in member HryUnam for method GetMembers for the MDDataProviderBW Business object (see MDDataProviderBW.GetMemberssa).

■       With pre-defined value sets, REFERENCE_HIERARCHY is filled with the corresponding technical name and is never empty.

For more information, see BI-Specific Enhancement: SAP VARIABLES Schema Rowset .

Variables can be displayed as follows:

·         single value such as a MEMBER_UNIQUE_NAME

·         interval as value area

·         complex selection of values (such as a list of single values or intervals connected to one another with OR).

selection options (special selection options can be entered via <option>, see BI-Specific Enhancement: MDX Syntax)
