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 . Cognos Analytics – How to Modify Filter Options for a Data Item Used in Filter Widget.
Because the desired result is a single member, the item function is used passing 0 as its index value argument to return only the current period member. 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.
Create a query object to host Relative Time.
For Rolling 13 Months. 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. Get the last date that has data. It is most flexible solution, however, it request report authors to have good understanding cognso MDX functions. RelativeTime values ‘R13M’, To explore the similar relative time functionalities in cube, this document is intended to provide three solutions to handle relative time, listed below: Then bring all three highlighted members into report query or cogns.
Option 1 handles it at database level: You can copy date dimension and then rename and adjust it. The solution will be demonstrated by using Cognos version The idea is to create a new relative time table. RelativeTime Parameter varchar 10Value int. The options above provide report user a clear framework manager model, however you need to change database or framework manager. In order to explain the concept, the following report is used.
Newer Post Older Post Home. Check list of all posts. Option 3 handles DMR relative time at Report level. To resolve this issue, this option is to provide a solution without change time dimension. Option 3 handles it at report level: The main disadvantage of option 1 is to change database when adding a new relative time. Posted by Charles Yin at The key point is to define a filter for each relative dimension.
RelativeTime values ‘CM’, Add an indicator in both database layer and business view layer.
At the same time, create all relative time dimensions at dimension layer. Based on this query, you can create a dynamic parameter map. When published, package looks as fellows.
In this case, create additional three columns as. Option 1 handles DMR relative time at database level. This approach is relatively flexible, and it is easy to use for report authors as well. Get the set of members from the Time dimension at the Date level. When published, the package should be displayed as follows. Add additional relative time flag columns in Time dimension, and update it on daily basis. Then make time filter dynamic based on relative time table.
Option 2 handles it at framework manager level: Hi with alternative 2, do I need to update the dates in the parameter map every month? This is a way to develop relative time based report without changing database and framework manager.

In this case only one member is returned since the integer argument is 1. The tail function returns a member set. Petter Huseby January 23, at Returning a member is important if you want to use this data item in another dimensional function. The value is actually a month key.

All three relative time is mapped as below. Please see query below. Now create each relative time as a separated dimension. Even DMR and cube both belongs multi dimensional reporting, DMR based report does present some challenges for relative time. This approach is not flexible, as you need to add column into database, but it is very easy to use for report authors.
When changing relative time, you only need to add record s. There are three relative time frames: Create each time hierarchy for each individual relative time. When there is any change for relative time, you need to only add records.
Option 2 handles DMR relative time at framework manager level. RelativeTime values ‘YTD’,
