This example configuration will add to recurring charge of parent item the summary recurring charge of all child items which have field IsIncluded set to true.
Params
As in regular Calculation step, put codes of pricing variables - the result is always stored in pricing variable, but as source you can put expressions containing pricing variables, fields and attributes. null, true, false constants are also properly evaluated.
