Quarter level aggregation for formula

Question

We are noticing discrepancies in calculation of qtd at quarter level (e.g. q12009 for a calculated formula). We use the following formula for calculating qtd amount and in example bleow the account type is 'E'. Can anybody advise the discrepancy seen.
IF CR_ID.ACCT_TYPE.ATTRIBUTE EQ 'E' THEN movingtotal(CR_CUBE_FIN.AMOUNT.MEASURE,(CR_PR_MONTH_IN_QTR-1)*-1,0,1,CR_PR) ELSE IF CR_ID.ACCT_TYPE.ATTRIBUTE EQ 'R' THEN movingtotal(CR_CUBE_FIN.AMOUNT.MEASURE,(CR_PR_MONTH_IN_QTR-1)*-1,0,1,CR_PR) ELSE NA

Answer 1

Original measure: CR_CUBE_FIN.AMOUNT.MEASURE
Create calc_meas1 for last along time calculation on CR_CUBE_FIN.AMOUNT.MEASURE (nov09 for qtr:2009Q3, dec09 for year:2009 etc.)
Create calc_meas2 for qtd calculations on CR_CUBE_FIN.AMOUNT.MEASURE (sum of months for qtr).
Create calc_meas3 for ytd calculations on CR_CUBE_FIN.AMOUNT.MEASURE (sum of months for year).
Create calc_meas4 for switching b/w
* calc_meas1 for account type 'A', 'L'
* CR_CUBE_FIN.AMOUNT.MEASURE for time_levelrel 'MONTH' and account type 'E', 'R'
* calc_meas2 for time_levelrel 'QUARTER' and account type 'E', 'R'
* calc_meas3 for time_levelrel 'YTD' and account type 'E', 'R'
You can expose only calc_meas4 in reporting layer (if desired/possible).
If you're using excel add-in etc, you can populate the description of calc_meas1, calc_meas2, calc_meas3 to something like " *** internal measure *** " and educate users not to use it for ad-hoc reports/calculations.
