I have a formula called Average Days that displays the average number of days between invoices. Here is the formula:
{@DateDiff Spread}/Count ({ARFID.INVOICE_NUMBER}, {ARFID.CUST_PART_ID})
Here is the DateDiff Spread formula referenced above:
(Maximum ({ARFIM.INVOICE_DATE}, {ARFID.CUST_PART_ID})-Minimum ({ARFIM.INVOICE_DATE}, {ARFID.CUST_PART_ID}))+{@Current Date - Max}
The Average Days formula is working and displaying the correct values. However, I need to be able to use its results as part of an aglorithm formula that assigns weights to other values then displays 1 final value.
When I reference the Average Days formula in another formula, I get an error:
"A summary has been specified on a non-recurring field.
Details: @Sales Sum"
Sales Sum is the formula that should display the final value. I think the issue is that I'm trying to reference a formula that references Maximum and Minimum summary values, but I'm not sure how to work around this.
Any help would be great.

try using shared variable formulas to get your other values

Thank you for the reply.
I haven't worked with variables much, but here is what I tried with no success.
I edited the Average Days formula to:
whileprintingrecords;
Shared NumberVar avgdays := {@DateDiff Spread}/Count ({ARFID.INVOICE_NUMBER}, {ARFID.CUST_PART_ID});
I then created a new formula called AvgDaysVariable and called the variable:
Shared NumberVar avgdays;
The variable value displays correctly but I'm still unable to use the variable value in another formula.
I tried using the variable in this formula:
({@QTY Previous 30 Days}*10)+{@QTY Previous Year}*1.5 + shared numbervar avgdays
I also tried calling the other formula field:
({@QTY Previous 30 Days}*10)+{@QTY Previous Year}*1.5 + {@AvgDaysVariable}
Either way, I'm still getting the same error.
