body: <p>i have a time dimension in the following format Year-> Quarter -> month</p>
  
  <p>but it fails to integrate correct results when doing month vs previous  month</p>

  <pre><code>IIF(
  ([Measures].[Measures].[Sales Euros],
  [v Time3].[KPI Month].CURRENTMEMBER.PARENT)=0,Null,
  ([Measures].[Sales Euros],
  [v Time3].[KPI Month].CURRENTMEMBER)/
  ([Measures].[Sales Euros],
