Hi

Situation

Hi @Misha ,

Please try following DAX:

Column = IF('Table'[Subtopic] = 
                MINX(
                    FILTER('Table','Table'[Topic] = EARLIER('Table'[Topic])
                ),
                'Table'[Subtopic]
                ),
                'Table'[Topic])

Best regards,
