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 .

Option 3 handles DMR relative time at Report level. This approach is relatively flexible, and it is easy to dmf for report authors as well.
When published, package looks as fellows.

In this case, create additional three columns as. 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. To resolve this issue, this option is to provide a solution without change time dimension.
Functiins values ‘CM’, Posted by Charles Yin at Option 3 handles it at report level: Option 1 fnctions it at database level: Conos order to explain the concept, the following report is used. Add an indicator in both database layer and business view layer.
Please see query below. You can copy date dimension and then rename and adjust it. Please note that you can define more complicated table, such as begin date, and end date.

In this case only one member is returned since the integer argument is 1. The idea is to create a new cognoos time table. For Rolling 13 Months. Create a query object to host Relative Time. The solution will be demonstrated by using Cognos version The options above provide report user a clear framework manager model, however you need to change database or framework manager. At the same time, create all relative time dimensions at dimension layer.
Filter the set of Date to find the members that have data for a measure you know only goes up to the current funcctions, in this case Revenue.
The main disadvantage of option 1 is to change database when adding a new relative time. 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. 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.
Option 2 handles DMR relative time at framework manager level. Option 2 ddmr it at framework manager level: Based on this query, you can create a dynamic parameter map.
Returning a member is important if you want to use this data item in another dimensional function. Hi with alternative 2, do I need to update the dates in the parameter map every month?

Create each time hierarchy for each individual relative time. The key point is to define a filter for each relative dimension. Get the last date that has data. The tail function returns a member set.
Then make time filter dynamic based on relative time table. This is a way to develop relative time based report without changing database and framework manager.
All three relative time is mapped as below.
When changing relative time, you only need to add record s. Instead of creating column for time dimension, a relative time table is created.
