Select a semantic model from the semantic model's column, then click a measure from the Measures column to view its properties.
Or, add a measure if needed.Choose Expression and enter the default value of 0 for simple expressions or enter the solve order.
Change the solve order if this expression needs to be calculated for use in another expression.Set the non-empty behavior to By Expression, By Measures, or By Measures Then Expression.
By Expression: The expression must evaluate itself to determine whether the calculated measure is empty.
By Measures: When you specify one or more measures in the list, the calculated measure is treated as empty if all the specified measures are empty.
By Measures Then Expression: The calculated measure is considered empty if all the specified measures are empty or if the expression evaluates to an empty value.
If By Measure or By Measures Then Expression is selected, select the measure used to evaluate the expression. Type in the Search box to quickly find a measure, or click a checkbox to select a measure from the list.
This option can improve query performance because the calculation is only done if the values used in it are not empty.Enter an expression that uses MDX Linear syntax.
