SSRS Subreport Error: Subreport could not be shown

Hi,

I have two reports called DailyProductionPackMatReport and DailyProductionIngRawReport, each with different sets of UIBuilder, Controller, Contract and DP. Both these reports have two same parameter fields ProdId and PickingDate but these parameters are being queried differently.

Report name	Parameters	Screenshot
DailyProductionPackMatReport	DailyProductionPackMatDS_ProdId DailyProductionPackMatDS_PickingDate
DailyProductionIngRawReport	DailyProductionIngRaw_ProdId DailyProductionIngRawDS_PickingDate

My requirement is to print these reports together in one click, hence the idea is to use subreport.

I tried calling DailyProductionIngRawReport from DailyProductionPackMatReport.

Here are the subreport properties:

DailyProductionIngRawReport with design named Report.

I passed DailyProductionPackMatReport parameters values as parameters for the subreport.

Turns out, when printing the subreport, I got Error: Subreport could not be shown.

How is this wrong? Please clarify.

Thank you very much.
