Create each time hierarchy for each individual relative time.

Add additional relative time flag columns in Time dimension, and update it on daily basis. Create a new table to host relative time as below. 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.

The idea is to create a new relative time table. Check list of all posts. This approach is not flexible, as you need to add column into database, but it is very easy to use for report authors. The solution will be demonstrated by using Cognos version Option 2 handles DMR relative time at framework manager level.

Get the set of members from the Time dimension at the Date 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. 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.

Newer Post Older Post Home. When changing relative time, you only need to add record s. RelativeTime Parameter varchar 10Value int.

To explore the similar relative time functionalities in cube, this document is intended to provide three solutions to handle relative time, listed below: All three relative time is mapped as below. When there is any change for relative time, you need to only add records. Get the last date that has data.

For Rolling 13 Months.

Even DMR and cube both belongs multi dimensional reporting, DMR based report does present some challenges for relative time. Please see query below. Petter Huseby January 23, at The value is actually a month key. Add an indicator in both database layer and business view layer. Hi with alternative 2, do I need to update the dates in the parameter map every month?

Cognos Know How: How to handle DMR relative time

Please note dmt you can define more complicated table, such as begin date, and end date. You can copy date dimension and then rename and adjust it. The key point is to define a filter for each relative dimension. 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.

The main disadvantage of option 1 is to change database when adding a new relative time. Now create each relative time as a separated dimension.

In this case, create additional three columns as. The tail function returns a member set. To resolve this issue, this option is to provide a solution without change time dimension.

RelativeTime values ‘CM’, This is a way to develop relative time based report without changing database and framework manager. There are three relative time frames: When published, the package should be displayed as follows. Returning a member is important if you want to use this data item in another dimensional function. Posted by Charles Yin at At the same time, create all relative time dimensions at dimension layer. Option 1 handles it at database level: RelativeTime values ‘R13M’, The options above provide report user a clear framework manager model, however you need to change database or framework manager.

This approach is relatively flexible, and it is easy to use for report authors as well. Then make time filter dynamic based on relative time table.

Based on this query, you can create a dynamic parameter map. In order to explain the concept, the following report is used. Option 1 handles DMR relative time at database level. RelativeTime values ‘YTD’, It is most flexible solution, however, it request report authors to have good understanding of MDX functions. Instead of creating column for time dimension, a relative time table is created. When published, package looks as fellows.

Then bring all three highlighted members into report query or report. Create a query object to host Relative Time.
