DMR FUNCTIONS IN COGNOS PDF

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 .

At the same time, create all relative time dimensions at dimension layer. This approach is relatively flexible, and it is easy to use for report authors as well.

This approach is not flexible, as you need to add column into database, but it is very easy to functikns for report authors. Then make time filter dynamic based on relative time table.

The tail function returns a member set. All three relative time is mapped as below.

Option 2 handles DMR relative time at framework manager level. When changing relative time, you only need to add record s. Create each time hierarchy for each individual relative time. This is a way to develop relative time based report without changing database and framework manager. Get the last date that has data. 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.

Add additional relative time flag columns in Time dimension, and update it on daily basis. Newer Post Older Post Home.

Option 3 handles DMR relative time at Report level. Option 2 handles it at framework manager level: Based on this query, you can create a dynamic parameter map. Check list dmg all posts. 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 need to change database or framework manager. In order to explain the concept, the following report is used. RelativeTime values ‘CM’, Posted by Charles Yin at Even DMR and cube both belongs multi dimensional reporting, DMR based report does present some challenges for relative time.

When there is any change for relative time, you need to only add records. The key point is to define a filter for each relative dimension. The idea is to create a new relative time table.

Please note that you can define more complicated table, such as begin date, and end date. You can copy date dimension and then rename and adjust it. Instead of creating column for time dimension, a relative time table is created. To resolve this issue, this option is to provide a solution without change time dimension.

In this case, create additional three columns as. To explore the similar relative time functionalities in cube, this document is intended to provide three solutions to handle relative time, listed below: Dmmr this case only one member is returned since the integer argument is 1.

Now create each relative time as a separated dimension.

Option 3 handles it at report level: Then bring all three highlighted members into report query or report. Create a new table to host relative time as below. Please see query below. When published, package looks as fellows. Filter the set cognnos Date to find the members that have data for a measure you know only goes cogons to the current period, in this case Revenue. Returning a member is important if you want to use this data item in another dimensional function.

It is most flexible solution, however, it request report authors to have good understanding of MDX functions. Hi functinos alternative 2, do I need to update the dates in the parameter map every month?

Option 1 handles DMR relative time at database level. 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.

When published, the package should be displayed as follows. There are three relative time frames:
