Based on this query, you can create a dynamic parameter map.

RelativeTime values ‘YTD’, You can copy date dimension and then rename and adjust it. There are three relative time frames: All three relative time is mapped as below.

It is most flexible solution, however, it request report authors to have good understanding of MDX functions. 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. Even DMR and cube both belongs multi dimensional reporting, DMR based report does present some challenges for relative time.

Now create each relative time as a separated dimension. For Rolling 13 Months. Check list of all posts. The idea is to create a new relative time table. RelativeTime Parameter varchar 10Value int. 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 value is actually a month key. Hi with alternative 2, do I need to update the dates in the parameter map every month? Option 1 handles DMR relative time at database level.

Please see query below. Add additional relative time flag columns in Time dimension, and update it on daily basis.

RelativeTime values ‘CM’, Create a new table to host relative time as below.

This approach is not flexible, as you need to add column into database, but it is very easy to use for report authors. Returning a member is important if you want functionns use this data item in another dimensional function.

In this case, create additional three columns as. Create a query object to host Relative Time. Then bring all three highlighted members into report query or report. At the same time, create all relative time dimensions at dimension layer. Option 2 handles it at framework manager level: Option 3 handles it at report level: Option 1 handles it at database level: This is a way to develop relative time based report without changing database and framework manager.

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. 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. The main disadvantage of option 1 is to change database when adding a new relative time.

Please note that you can define more complicated table, such as begin date, and end date.

When published, the package fuctions be displayed as follows. When changing relative time, you only need to add record s.
