Many to Many relationship

Hi meghansh 

Please try this:

Here's the sample data:

Then add a calculated table:

Table = 
	SELECTCOLUMNS(
		FILTER(
			CROSSJOIN(
				'Course',
				SELECTCOLUMNS(
					'Phase',
					"_phase", 'Phase'[phase],
					"_CourseID", 'Phase'[CourseID],
					'Phase'[comment]
				)
			),
			'Course'[CourseID] = [_CourseID] && 'Course'[phase] = [_phase]
		),
		'Course'[CourseID],
		'Course'[phase],
		'Course'[start date],
		'Course'[end date],
		'Phase'[comment]
	)

The result is as follow:

Best Regards
