I am trying to execute a sub report from my master report. My master report has a datasource which return multiple rows. For each row I want to execute my sub report. So I have a sub report in detail section of my master report. However, when I select sub report source and pass ReceiptGUID parameter as = Fields.ReceiptGUID I am getting following error while trying to preview it:
"An error occurred while processing the report. Processing cancelled. Check the InnerException for more details. Invalid value of report parameter "ReceipGUID".
Can someone help me with this? I tried checking in forum and existing solutions are not fixing it.
When I pass a constant string as report parameter, it works fine. I have checked the result set from the master report datasource and it returns ReceiptGUID as expected for each row.
