User LIS average ratios instead of sum

Question

Hi guys,
Im creating a user LIS, i know that when creating LIS on MC21 there is flag with indicates if its reasonable to add the values on this ratio, and i need to know if by any chance instead of adding the rations on LIS, system can make an average of them. See in LIS MCI7 system calculate MTBF & MTBR and average them, how can i make that with a user created ratio.
Thanks.

Hello,
Plese see below the correct syntax for the SUM function
The following examples are applicable to both Basic and Crystal syntax:
Sum({file.QTY})
Calculates the sum of all values in the QTY field.
Sum({orders.AMOUNT}, {orders.CUSTOMER ID})
Sums (totals) the orders in each group of orders in the Amount field. The orders are separated into groups whenever the value in the Customer ID field changes.
Sum({orders.AMOUNT}, {orders.DATE}, "monthly") % Sum({orders.AMOUNT })
Groups values in the Amount field by month, and calculates the sum of the values for each month group as a percentage of the sum of the values for the entire report.
Sum([{file.AMOUNT}, {file.PRICE}, {file.COST}])
Sum of values in the Amount, Price, and Cost fields.
