Add a column to a report that would get sum or count values from another table

[Samar A]

I am building a report and need help to include columns to show the sum or count from a different table.

For example, I have table-1 that lists all the students and the tutor class they are enrolled in.  Table-2 tracks all the time spent in tutor classes.  The custom column would show the sum of hours for each student in each tutor class.

Table-1:

Student-1 Math

Student-1 Writing

Student-2 Math

Table-2:

Student-1 Math     07.01.24 2 hr

Student-1 Math     08.10.24 2 hr

Student-1 Math     08.13.24 1 hr

Student-1 Writing 08.03.24 1 hr

Student-2 Math     07.03.24 1 hr

Student-2 Math     08.08.24 1 hr

Student-2 Math     08.18.24 2 hr

Report:

Name        Class     July24   August24

Student-1 Math     2 hr       3 hr

Student-1 Writing 0            1 hr

Student-2 Math     1 hr       3 hr

Thanks.

I missed to include in my post to ask how do you add the columns that has the sum(hours) to the report.

If you add one more field for table 2 - 'Month" (can be calculated based on the date field), you can achieve it with multi-pivot table report on top of table 2:

Rows: Name, Class

Column: Month

Aggregation - class duration
