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 .

RelativeTime values ‘CM’, The idea is to create a new relative time table. Option 1 handles it at database level: RelativeTime values ‘R13M’, In funnctions to explain the concept, the following report is used. Without applying any changes in database and framework manager, you can dynamically figure out current date, and functiohs apply MDX time functions to determine all periods as requested on the fly. This approach is not flexible, as you need to add column into database, but it is very easy to use for report authors.
The tail function returns a member set. You can copy date dimension and then rename and adjust it.
Hi with alternative 2, do I need to update the dates in the parameter map every month? Returning a member is important if you want to use this data functoins in another dimensional function. Create a new table to host relative time as below.
The main disadvantage of option 1 is to change database when adding a new relative time. When published, package looks as fellows.
All three relative time is mapped as below. Option 3 handles DMR relative time at Report level.
For Rolling 13 Months. Get the last date that has cogns. There are three relative time frames: The key point is to define a filter for each relative dimension. Add an indicator in both database layer and business view layer.
To resolve this issue, this option is to provide a solution without change time dimension. Even DMR and cube both belongs multi dimensional reporting, DMR based report does present some challenges for relative time. RelativeTime values ‘YTD’, Get the set of members from the Time dimension at the Date level. Then make time filter dynamic based on relative time table. Option 2 handles it at framework manager level: 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.
When there is any change for relative time, you need to im add records. Then bring all three highlighted members into report query or report. Option 3 handles it at report 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 options above provide report user a clear framework manager model, however you need to change database or framework manager. This is a way to develop relative time based report without changing database and framework manager.
Now create each relative time as a separated dimension. Option 1 handles DMR relative time at database level. Instead of creating column for time dimension, a relative time table is created.
Create each time hierarchy for each individual relative time. Please see query below. Create a query object to host 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 approach is relatively flexible, and it is easy to use for report authors as well. When published, the package should be displayed as follows. Based on this query, you can create a dynamic parameter map.
It is most flexible solution, however, it request report authors to have good understanding of MDX functions.
Petter Huseby January 23, at Newer Post Older Post Home. Option 2 handles DMR relative time at framework manager level. In this case, create additional three columns as. Add additional relative time flag columns fuhctions Time dimension, and update funcrions on daily basis. Check list of all cogbos. At the same time, create all relative time dimensions at dimension layer.
RelativeTime Parameter varchar 10Value int. Please note that you can define more complicated table, such as begin date, and end date. When changing relative time, you only need to add record s.
