The result of this function returns the member from the Year level as shown in Illustration 3. Illustration 3: Cognos Viewer showing the member returned from the Year level of the Time dimension This function can be used for any level within the dimension. For example, you can use the Month level as shown below. However, it can still be determined by finding the latest period that has data for a given measure.

Arasar When there is any change for relative time, you need to only add records. Hi with alternative 2, do I need to update the dates in the parameter map every month? Based on this query, you can create a dynamic parameter map. Please see query below.
When published, the package should be displayed as follows. Option 1 handles DMR relative time at database level. At the same time, create all relative time dimensions at dimension layer. 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. When changing relative time, you only need to add record s. Add additional relative time flag columns in Time dimension, and update it on daily basis. The options above provide report user a clear framework manager model, however you need to change database or framework manager. The value is actually a month key.
Option 3 handles it at report level: All three relative time is mapped as below. 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. Option 2 handles DMR relative time at framework manager level. You can copy date dimension and then rename and adjust it. This approach is relatively flexible, and it is easy to use for report authors as well.
This functiions a way to develop relative time based report without changing database and framework manager. End of Support for Rational Insight 1. Add an indicator in both database layer and business view layer.
The solution will be demonstrated by using Cognos version Get the last date that has data. Create a query object to host Relative Time. Instead of creating column for time dimension, a relative time table is created. TOP Related Posts.

In this case only one member is returned since the integer argument is 1. Create a new table to host relative time as below. Option 2 handles DMR relative time at framework manager level. In order to explain the drm, the following report is used. At the same time, create all relative time dimensions at dimension layer.
IBM Cognos BI – Using Dimensional Functions to Determine Current Period
When published, the package should be displayed as follows Then bring all three highlighted members into report query or report Option 2 handles DMR relative time at framework manager level The main disadvantage of option 1 is to change database when adding a new relative time. To resolve this issue, this option is to provide a solution without change time dimension. The idea is to create a new relative time table. When changing relative time, you only need to add record s. Database Add an indicator in time dimension column for the sake of query engine, which will be explained later Alter table [gosales]. RelativeTime Parameter varchar 10 , Value int insert into [gosales]. Please note that you can define more complicated table, such as begin date, and end date.
