DMR Functions in Framework Manager. «on: 18 Nov am». Hello Folks, I am working on Cognos BI version, I have created a DMR model. Hi khayman, Ya, I am new to dimensional functions. I have to add simple ancestor() and Bottoncount() functions. I create a data item is. Could you please suggest how to achieve this scenario using DMR model. * Regards, DMR Function to get Previous Year Data. 6. Answers. 0 .

Petter Huseby January 23, at In order to explain the concept, the following report is used.

Instead of creating column for time dimension, a relative time table is created. RelativeTime values ‘YTD’, Add additional relative time flag columns in Time dimension, and update it on daily basis. When there is any change for relative time, you need to only add records.

RelativeTime Parameter varchar 10Value int. Option 1 handles it at database level: Cohnos values ‘R13M’, To resolve this issue, this option is to provide a solution without change time dimension.

Create each time hierarchy for each individual relative time. Get the set of members from the Time dimension at the Date level. The options above provide report user a clear framework manager model, however you fknctions to change database or framework manager.

Filter the set of Date to find the members that have data for a measure you know only goes up to the current period, in this case Revenue. This is a way to develop relative time based report without changing database and framework manager.

Without applying any changes in database and framework manager, you can dynamically figure out current date, and then apply MDX time functions to determine all periods as requested on the fly.

In this case only one member is returned since the integer argument is 1. When published, package looks as fellows. In this case, create additional three columns as. The tail function returns a member set. When published, the package should be displayed as follows. At the same time, create all relative time dimensions at dimension layer. Hi with alternative 2, do I need to update the dates in the parameter map every month? When changing relative time, you only need to add record s.

Check list of all posts. Even DMR and cube both belongs multi dimensional reporting, DMR based report does present funcyions challenges for relative fognos. Option 2 handles it at framework manager level: RelativeTime values ‘CM’, Create a query object to host Relative Time. Please see query below. Because the desired result is a single member, the item function is used passing 0 as its function value argument to return only the current period member.

Posted by Charles Yin at Another key pint is to define top level member, somehow you need to add a reference of date dimension, so that the query engine know to apply the filter of the used dimension. Then bring all three highlighted members into report query or report. Please note that you can define more complicated table, such as begin date, and end date.

Option 3 handles it at report level: The main disadvantage of option 1 is to change database when adding a new relative time. You can copy date dimension and then rename and adjust it. Option 1 handles DMR relative time at database level.

Option 2 handles DMR relative time at framework manager level. Then make time filter dynamic based on relative time table. Create a new table to host relative time as below. Now create each relative time as a separated dimension.
