Instead of creating column for time dimension, a relative time table is created. Option 2 handles it at framework manager level: For Rolling 13 Months.
Option 3 handles DMR relative time at Report level. Without functionss 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. Because the desired result is a single member, the item function is used passing 0 as its index value argument to return only the functiobs period member.
When changing relative time, you funtions need to add record s. Option 2 handles DMR relative time at framework manager level. At the same time, create all relative time dimensions at dimension layer. Even DMR and cube both belongs multi dimensional reporting, DMR based report does present some challenges for relative time.

To explore the similar relative time functionalities in cube, this document is intended to provide three solutions to handle relative time, listed fucntions The value is actually a month key.

When there is any change for relative time, you need to only add records.
Then bring all three highlighted members into report query or report. Fundtions is most flexible solution, however, it request report authors to have good understanding of MDX functions. Please see query below. RelativeTime values ‘CM’, 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.
RelativeTime values ‘YTD’, 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. Newer Post Older Post Home.
