Hi,
I am having the same problem as this thread:
date-grouping-in-subreport-not-working
However, the solution there did not work for me. To summarize, I have a main report with one group and a subreport with two linked parameters. The subreport is in the group header of the main, and this group field is also the linked field. This is working properly, the parameter is set by the group. The second parameter is not working properly though. It only returns one record when it should be returning multiple records.
My thoughts were to:
1. Make the parameter optional
2. Allow multiple values
3. Set the default value for the parameter
4. Allow null values
These are parameters created by Crystal when the subreport links are created. When I go into the subreport, right-click the parameters, the edit option is not there. I also tried to create my own parameters in the subreport, edit those accordingly, and link to them instead, but when I tried to link to them the "Select data based on subreport field" option was disabled.
