Check list of all posts. Option 1 handles it at database level: 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. The solution will be demonstrated by using Cognos version 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.
Cognos Know How: How to handle DMR relative time
To explore the similar relative time functionalities in cube, this document is intended to provide three solutions to handle relative time, listed below: This is a way to develop relative time based report without changing database and framework manager.
Create a query object to host Relative Time. Newer Post Older Post Home. Option 2 handles DMR relative time at framework manager level.
End of Support for Rational Insight 1.1.0
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 tunctions the used dimension. 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? When published, the package should be displayed as follows. When there is any change for relative time, you need to only add records.
Petter Huseby January 23, at Add an indicator in both database layer and business view layer. The key point is to define a filter for each relative dimension. Option ufnctions handles DMR relative time at Report level.
This approach is not flexible, as you need to add column into database, but it is very easy to use for report authors. Option 3 handles it at report level: Get the set of members from the Time dimension at the Date level. The main disadvantage of option 1 is to change database when adding a new relative time.
RelativeTime values ‘R13M’, It is most flexible solution, funchions, it request cognox authors to have good understanding of MDX functions. RelativeTime Parameter varchar 10Value int.
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. There are three relative time frames: Based on this query, you can create a dynamic parameter map.
In cognow case, create additional three columns as. When published, package fknctions as fellows.

To resolve this issue, this option is to provide a solution without change time dimension. Instead of creating column fhnctions time dimension, a relative time table is created.
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.
The options above provide report user a clear framework manager model, however you need to change database or framework manager. The idea is to create a new relative time table.
