Survey Plain Text Data - Setting Minimum Response Threshold
Hello everyone! I've got a puzzler here that I'd love to get some perspective on.
As part of a larger survey results dashboard, I have created a table visualization that shows plain text comments associated with individual identifiers. The visualization is filterable many ways. In some cases, a user would be able to filter down to fewer than 5 individual respondents, which exposes people's identity. This is the challenge I'm trying to fix.
For individual measures, I have a good solution:
Census - Inorganic Growth Employee Count = var result = DISTINCTCOUNT('Census - Inorganic Growth'[Empl ID])
return IF(DISTINCTCOUNT('Census - Inorganic Growth'[Empl ID]) >= 5, result)
The above works well for summary scores and most visualizations. However, I need to implement the same type of strategy to output a table. Here's the code I'm using right now -- it throws an error:
Error received:
The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value.
This seems like it might have a relatively simple fix. Any ideas? Thank you so much!

Anonymous , seen like you are still creating a measure, not a table, that is why this error.
Also, I doubt you need to have some grouping involved at what level it should be >5. and that need a different approach
Thank you for helping, amitchandak ! I changed the DAX expression to be in a "new table," but still am getting the same error.
I can't group the employee ID numbers; they need to be filterable many different ways. Maybe I'm misunderstanding?
Hi Anonymous ,
This error cause by if statement in Power BI.
Currently as far as I know, if statement not support to return table or multiple columns as expressions result. If statement should return a specific sclar value instead of table value. In addition, Power bi not support to create dynamic calculated column/table based on filter/slicer.
