mlopez_1 Posted January 25, 2018 Share Posted January 25, 2018 You must return the list to main report for using from subreport.Search in doc, there are guides that will helo you.Mariano Link to comment Share on other sites More sharing options...

markus.weisser Posted January 29, 2018 Author Share Posted January 29, 2018 Hi Mariano, thank you for the hint. I checked the reference. But i think my problem is, that i'll have to pass a sum out ofa list object not a sub report. When i click the List Options, i can see Parameters, Parameter Map but i'm missing Return Values Button...Do you have a clue how i can pass a value from a list to the main report?

mlopez_1 Posted January 30, 2018 Share Posted January 30, 2018 I don't understand where there problem is, I think that I don't know your purpose.When I have to return values from a subreport, first define variable in main report and subreport, then from main report select subrepot and 'Subreport return values' and map both variables.This all I do.Mariano Link to comment Share on other sites More sharing options...
markus.weisser Posted January 31, 2018 Author Share Posted January 31, 2018 Hello Mariano, again: I try to retrieve the data NOT from a sub report, i'm trying to do it with a list object.With a list object, you don't have the "Subreport return value" Button...byeMarkus Link to comment Share on other sites More sharing options...
