The variable derives its value from a CURRENT MEMBER variable.
To define filters that relate to the values of a time characteristic in the drilldown of a query during analyses, define a restricted key figure using a CURRENT MEMBER variable. This is a variable with the replacement path CURRENT MEMBER.
The CURRENT MEMBER variable can be used in restricted key figures as either the lower limit or the upper limit in combination with an offset. Only one restriction with a CURRENT MEMBER variable is allowed per restricted key figure however.
