## Calculated member to calculate % of sales of a parent

 Author Message michielbijnen SSC Journeyman Group: General Forum Members Points: 91 Visits: 145 Hi,I have an issue with a calculated member in SSAS 2008R2. I think it's relatively simple but I can't get my hands on it. I am relatively new in MDX.I have a dimension [Projects] with a hierarchy called [Parent Project]. This hierarchy has the attributes [Parent Projectno] on top and then [Projectno].As measures I have [Sales] and [Cost of Sales] and a calculated member [Gross Margin] that calculates ([Measures].[Sales] - [Measures].[Cost of Sales]).So far no problems.What I would like to have is the ratio (as a percentage) of the gross margin (GM) per project to the gross margin of the parent project.So for example:Parent project 800 holding projects 810, 812 and parent project 900 holding projects 901, 902 and 903.GM project 810 = 2.000GM project 812 = 3.000GM parent project 800 = 5.000GM project 901 = 10.000GM project 902 = 5.000GM project 903 = 15.000GM parent project 900 = 30.000So when I drag the hierarchy [Parent Project] to the cube browser in BIDS and browse all parent projects the percentages per project should be (when I click to the project-level):810: 40% (=2000/5000)812: 60% (=3000/5000)800: 100%901: 33,3% (=10000/30000)902: 16,7% (=5000/30000)903: 50% (=15000/30000)900: 100%My MDX-expression in the Calculations-tab in BIDS shows this, but it does not give me the correct percentages on the project level.I have tried several scenarios but to no avail.The last 2 scenarios are:Scenario 1 (not working):CASE WHEN IsEmpty([Measures].[Gross Margin]) THEN NULL When [Projects].[Parent Project].[Projectno].CurrentMember.Level Is [Projects].[Parent Project].[Projectno].[(All)] Then 1 Else ( [Projects].[Parent Project].[Projectno].CurrentMember, [Measures].[Gross Margin] ) / ( [Projects].[Parent Project].[Parent Projectno].CurrentMember, [Measures].[Gross Margin] )ENDScenario 2 (not working):CASE WHEN IsEmpty([Measures].[Gross Margin]) THEN NULL When [Projects].[Parent Project].[Projectno].CurrentMember.Level Is [Projects].[Parent Project].[Projectno].[(All)] Then 1 Else ( [Projects].[Parent Project].[Projectno].CurrentMember, [Measures].[Gross Margin] ) / ( [Projects].[Parent Project].[Projectno].CurrentMember.Parent, [Measures].[Gross Margin] ) EndWhat's wrong?Hope someone can help me out.Thanks!Michiel
