I will keep functons if there are any other issues. Do you have any idea? Hi, Have you tried generating categories always irrespective of the data in fact. It worth noting that these functions are written by IBM, and are liable to change on upgrade.

This will get all months in the Time dimension:. But the calculated fileld ‘XYZ’ is still populating with the rolling total. In the current year I want the line to stop at previous week.

The trick is to use the if function. Hi Andy, Is this a relational data source? From the right cofnos you can quickly select other members, dimensions, operators or functions to insert them in the calculation formula.

The concept of a running-total is relational concept. I am able to calculate the moving-total in ascending order, is there a way to calculate the moving-total in mx order? Cognos will only execute the substring function when it draws the results on the crosstab.

But sometimes you need to pass a different argument to these functions. Any help would be much appreciated. For example, these expressions will return the members for the month of the current date and the week of current date: Funftions put them into tuples exactly as I would expect.

Is there cognis way to do a running-total using a year dimension with a seperate month dimension? To start create a new line graph report. The calculations will run during each report execution and be available alongside the stored members. Notify me of follow-up comments by email. Quite frequently you would like to filter set members using some condition. Create a new data item called SelectedA: I have a cube based repport that currently working on a prompt where user selects timeframe.

Macros Part 2 of? Notice the major difference is the tuple in the beginning. For example, a set of months on the crosstab rows.

Calculated members

Now that you know how to select different sets of dimension members you can calculate different aggregated values from these sets:. Since a relational table can be visualized in only two dimensions it is very easy to understand ndx visualize running and moving aggregates. You can perform arithmetic calculations also for calculated members in the other dimension.

It looks like IBM is wisening up to my tricks. The expression in the series is processed for each item in the ordinal axis. What you can do instead is reference the YTD as the default value in the prompt macro: It took a few trials to convince some people that the report was actually running funnctions not being retrieved from cache.

If it will be combined with a year then it will show the growth comparing to the previous year. As far as I am aware they are using Cognos The generate function will evaluate the head descendants currentMember expression for each member in the years level.

This allows for much more efficient reports, while still functilns you with the results you expect. HI Paul functilns Great explanation. To find out more, including how to control cookies, see here: Looks like it is working now. Sometimes you want to return a default value if some measure or function will return an empty value.

Conceptually it is easy to understand that, as you cannot find the intersection between two points on the same line.

Uncategorized Javascript 10 Prompts 8. At present I am using only these 2 values in columns and months in rows. Those expressions would only work if the measure is 0 for future months.

In other, completely unrelated news, I will be selling opportunities for selfies with me in Think ! User now wants to schedule the report cognnos timeframe is YTD. It is not coming in the crosstab. One of the problems often faced when working with true dimensional sources as opposed to DMR which will not be discussed here, ever is working with dates.

For example, the following expression will return set of last fucntions days from [Time]. If I understand correctly your crosstab shows the EmpCount for each A for each month. I get no errors. I am using running count in my query to calculate the number of occuerence of the the data item.
