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 .

When changing relative time, you only need to add record s. The tail function returns a member set. This approach is not flexible, as you need to add column into database, but it is very easy to use for report authors. Check list of all posts. All functione relative time is mapped as below. Posted by Charles Yin at Get the last date that has data.

At the same time, create all relative time dimensions at dimension layer. Because the desired result is a single member, the item function is used passing 0 as its index value argument to fynctions only the current period member.
Option 1 handles it at database level: Option 1 handles DMR relative time at database level. Hi with alternative 2, do I need to update the dates in the parameter map every month? For Rolling 13 Months. The main disadvantage of option 1 is to change database when adding a new relative time. Returning a member is important if you want to use this data item in another dimensional function. Option 3 tunctions it at report level: Petter Huseby January 23, at You can copy date dimension and then rename and adjust it.
To explore the similar relative time functionalities in cube, this document is intended to provide three solutions to handle relative time, listed below: It is most flexible solution, however, it request report authors to have good understanding of MDX functions.

Add additional relative time flag columns in Time dimension, and update it on daily basis. Please note that you can define more complicated table, such as begin date, and end date. RelativeTime Parameter varchar 10Value int. Based on this query, fuhctions can create a dynamic parameter map.
To resolve this issue, this option is to provide a solution without change time dimension. The solution will be demonstrated by using Cognos version RelativeTime values ‘R13M’, In this case only one member is returned since the integer argument is 1. This approach is relatively flexible, and it is easy to use for report authors as well.
Now create each relative time as a separated dimension. The value is actually a month key. This is a way to develop relative time based report without changing database and framework manager. Another key pint is to define top level member, somehow you need to add a reference of date dimension, so that the query djr know to apply the filter of the used dimension.
Create a new table to host relative time as below. 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. Please see query below. Option 2 handles DMR relative time at framework manager level.
The idea is to create a new relative time table. Option 3 handles DMR relative time at Report level. Create a query object to host Relative Time.
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. Instead of creating column for time dimension, a relative time table is created.
