If you've applied filters that yields no results to a report in the Custom Report Writer, you'll get this message: "Nothing matched that query. Please change the filter and try again."
Follow the instructions below if you've applied a filter to a report in the Custom Report Writer but it hasn't given you any results. You'll need to edit your report.
Step 1 - Check your filter
You may have added a filter where no students match the criteria.
For example, I have no Gypsy / Roma / Traveller students, so if I add a filter for this, my report won't show any students.
Try using the Global Search to have a look at the student group. For example, I went to Students > Demographics > Derived Indicators > Background > Gypsy / Roma / Traveller.
Step 2 - Check if you've applied more than one filter
Your filters might be contradicting each other. Here are the filters I've set - I wanted my report to only show students who were in the registration forms 1MJ or 1TP.
However, my report is actually showing students who are part of both 1MJ and 1TP. This would be none of my students, because students are only in one registration form today.
You can click the bin icons next to these filters to delete them. Then, add a new filter for Registration form (not for the name of the student group with a question mark ? at the end).
In the slide over, select the groups of students you want to be included under Is one of, then click Save.
When you Save and view your report, it will show only students in 1MJ or 1TP.
