RE: Management Reporter - Column/Period options
I was unaware of the feature Susan points out, which was supported by FRx - Management Reporter does support the following:
Column A = 1:BASE - if you use this for the FD: ACTUAL, this should get you through the whole year.
Column B = 2:12 - if you use this for your FD:BUDGET, this should present budget info for 2-12, in subsequent periods you would deduct one from the numeric value in this column, until you reach year-end.
Use Print Control: NP on columns A and B so they do not show on the report.
Column C = CALC; Formula = A + B
I would recommend, you create a separate report for each fiscal period, to be run in that fiscal period, so changes don't need to be made monthly or annually to these reports. I think the issue with the functionality as you desire it, is you're using one financial dimension (Actual) in the first column, and another financial dimension (Budget) in the second column, so the feature that support a rolling 12 month period does not apply.
My solution only works if these reports are meant to cover the periods in a year, rather than produce a true rolling 12 month period analysis. Perhaps someone at Microsoft can weigh in on whether or not we're missing a supported function here?
