DAX - counting based on two columns
Hi,
I am fairly new to DAX. I have been struggling all day to solve a particular problem and would be grateful if someone can help guide me. I have a list of customers and data looks like this (dummy example):
| Customer ID | Choice |
| 101 | Desk |
| 101 | Chair |
| 101 | Chair |
| 102 | Chair |
| 102 | Chair |
| 103 | Desk |
| 104 | Desk |
| 104 | Chair |
| 105 | Chair |
| 105 | Chair |
| 105 | Desk |
| 105 | Chair |
| 106 | Desk |
Eash customer can have multiple entries. However I want to extract only the ID of those customer who have chosen "Chair" only and nothing else - in this example 102 and 106. I have scratched my head and tried different thing and have failed.
Thank you.
Bharat
I would suggest creating either a calculated column or measure using this code:
Chair only = IF ( CALCULATE ( SELECTEDVALUE ( Choices[Choice] ), ALLEXCEPT ( Choices, Choices[Customer ID] ) ) = "Chair", 1 )Then apply a visual level filter (or any sort of filter in the case of a calculated column) Chair only = 1

Will this not also count those customer IDs who have chair and desk or table? I want only those customers who have chair and nothing else as a selection.
