Transfer a parameter from report to subreport 1

[ipm]

Is it possible to transfer a parameter or any othe data from report to subreport?

You can link parameters that are created in the main and subreports, or you can link fields in the subreport with parameters in the main report. If you need to pass data from main to subreport or from subreport to main, you need to use shared variables.

How to use these shared variables?

 

[Madawc]

To pass data back from a subreport, use a shared variable. For a datam satm nake a formula field in the subreport like
Shared dateVar
V_Today := {LoadStatus.LastDLoad}
To access it in the main report, create another formula field with
Shared dateVar
V_Today := V_Today

If it was a currency value, you'd do it differently, e.g.
whileprintingrecords;
shared currencyvar SumSaved;
SumSaved:={#TotSaved};
SumSaved
And to access it in the main report, create another formula field with
whileprintingrecords;
shared currencyvar SumSaved;
SumSaved

Note that the shared variable is only available in the section after the section which contains the subreport.
