DAX command from a string

Anonymous — Fri, 14 Jan 2022 11:27:09 GMT

Hi,

I was wondering if it is possible to store all my DAX measures in a field in a table.

I'm thinking about creating a kind of knowledge base whre I can store all the measures my company could use. In this table I would have a text field contaning the measure itself, plus others fields for example to explain what the measure does, what are the tables necessary to excute them and may others informations.

I know I can store the measure as a string, but how would I convert that string into a valid DAX command in Power BI?

Is this possible?

Thank you.

Hi,

I was thinking like this:

I have a table called MEASURE_TABLE. In it I would have a varchar field where I would store a measure:

idMEASURE dscMEASURE_NAME dscMEASURE_COMMAND

-----------------------------------------------------------------------------------------------------------

1 DB Date Difference DATEDIFF(MIN(Calendario[Date]), MAX(Calendario[Date]),DAY) + 1

Would it be possible to convert the last 2 fields to a valid measure in Power BI?

It's kind of what you can do in T-SQL when you create a command based on a string and execute it.

Thanks.

Anonymous yes it is absolutely possible. If you are publishing the model in a workspace, you can write DMV queries that would return all your measures in a table

select * from $SYSTEM.TMSCHEMA_MEASURES
