How to calculate average sales per month based on the filtered date range
Hello,
I have a saved search that calculates historical item sales and a monthly sales average. The issue is if I change the date range to include says the first quarter, the formula in the saved search is dividing that by 12 to get the average per month. It does this regardless of the amount of months being report. Below is the line doing this calculation. How do I make the search respect the date range filter and divide by the correct amount of months?
(CASE WHEN TO_CHAR({transaction.trandate}, 'MON') = 'JAN' THEN {transaction.quantityshiprecv} ELSE 0 END + CASE WHEN TO_CHAR({transaction.trandate}, 'MON') = 'FEB' THEN {transaction.quantityshiprecv} ELSE 0 END+ CASE WHEN TO_CHAR({transaction.trandate}, 'MON') = 'MAR' THEN {transaction.quantityshiprecv} ELSE 0 END+ CASE WHEN TO_CHAR({transaction.trandate}, 'MON') = 'APR' THEN {transaction.quantityshiprecv} ELSE 0 END+ CASE WHEN TO_CHAR({transaction.trandate}, 'MON') = 'MAY' THEN {transaction.quantityshiprecv} ELSE 0 END+ CASE WHEN TO_CHAR({transaction.trandate}, 'MON') = 'JUN' THEN {transaction.quantityshiprecv} ELSE 0 END+ CASE WHEN TO_CHAR({transaction.trandate}, 'MON') = 'JUL' THEN {transaction.quantityshiprecv} ELSE 0 END+ CASE WHEN TO_CHAR({transaction.trandate}, 'MON') = 'AUG' THEN {transaction.quantityshiprecv} ELSE 0 END+ CASE WHEN TO_CHAR({transaction.trandate}, 'MON') = 'SEP' THEN {transaction.quantityshiprecv} ELSE 0 END+ CASE WHEN TO_CHAR({transaction.trandate}, 'MON') = 'OCT' THEN {transaction.quantityshiprecv} ELSE
