I need a running total formula to calculate cumulative values. How can I implement something similar to this:
<code>
IF TOTEXT(MONTH({OINV.DocDate}),'0')= {@Month Grouping} AND YEAR({OINV.DocDate}) = 2016 THEN
{@Current Year Sales Per Rep} + previous({@Current Year Sales Rep}
<code\>
This formula gives this specific error:
A summary has been specified on a non-recurring field.
