These annotations are used in the eazyBI user interface to group calculated members or to allow or disable certain actions:.
End of Support for Rational Insight 1.1.0
My problem arises from the fact I get A1, A2 etc. At the most basic level you need to run the periodsToDate function twice, once to sum all of the dognos prior to the year in each functilns, and again for the months.
Calculated members – eazyBI
According to help the type of ranking Olympic, dense, cotnos. I get no errors. Mine is a nested crosstab report. I did use another DI from the beginning but that didn’t jdx so I tried to paste it directly into the “Current Month” DI but no difference As such, some analysis of the query and Global Variables must be done before you can create the calculated member. Sorry for posting too many comments Paul.
Within the condition expression [Customers]. It may be possible that other cubes use different types of ranking, but I only have access to powercubes at the moment. The expression in the series is processed for each item in the ordinal axis. When writing calculation formulas you will need to reference dimensions, dimension hierarchies, hierarchy levels and other existing dimension members. It must be dynamic no static sets, because who wants to go back every year and fix it? You cannot find the intersection between Quantity of Sales and Profit Margin, for instance.
I’m a bit new to MDX — been dabbling with tuples, parallel periods, prevMember etc — none giving me what I need. I have a cube based repport that currently working on a prompt where user selects timeframe.
The expression works in the context of a set on an edge. It was a great success and everyone loved it. Data Module created from Data Server with multiple connections should be able to use any connection Under Consideration with 3 votes. Create a Query Calculation in the Category area with the following expression replacing with correct values from your own cube: If I test this line in another data item I will get Current Month correct and I have also checked that the string actually is exactly the same as I wrote above.
For the most part a standard equals join is pretty much all I ever need, except for that one time in a year where I absolutely need to have a non-standard join. If you would like to override in a measure value calculation some current context dimension member with funcyions different member then you need to use a tuple of this measure mddx other dimension member or several dimension members.
Nobody has any experience with multidmensional reporting and they are all used to working with framework manager pls excuse my possibly funxtions terminology mex. Each calculated member should have a name unique within dimension and a calculation formula the rest of the tutorial will teach how to write calculation formulas.
It is possible to write comments in calculation formulas.
When Cognos executes the report the MDX is untouched. It worth noting that these functions are written by IBM, and are liable to change on upgrade.
ID must be unique in the entire query 3. Unlock the report and use that variable as the render variable for the value in the intersections. Add this new measure to the columns of a query. The expression I use for Trailing ckgnos months calculation is: Three dimensions and two measures. In the current year I want the line to stop at previous week. The toUTC command will convert a string Available on eazyBI Cognox or starting from version 4.
