Cost Center Masterdata in BW is currently time dependent and therefore restricts users from doing year over year comparisons based on valid masterdata for a given time period.
The business would like to do year over year reporting with masterdata being valid for the given time period. For example, if 2011 Cost Centers are being compared to 2012 the masterdata for 2011 must display for that result set and 2012 masterdata for that year in the same report. Currently BEx offers a key date field in the query properties that only allows the user to chose a single date for a given year. This limits the users ability to do year over year comparisons with relevant masterdata.
please suggest me some solution.
