Problem adding a new column

[Anonymous]

I am having a problem adding a new column to a table 
If I add a new column and use some trivial formula for it (For example NewColumn = 7) it works.
When I try to use the code I need, PBI desktop seem to reject the code and the formula remains blank. However, the code seems to be OK, because if a modify an existing column using this same code, it is accepted and the results are OK.

Any ideas?

Thank you!

Hi @Anonymous 

In order to help you better if your problem is not solved yet, I need to know what is your data connection mode? If it is direct query mode, it will have some limitations, For more details, you can read related document link:

 Hi @Idrissshatila

Not sure what can I share to show you what is happening. Are you asking for uploading the Power BI data model? Don't see how this can be done.

The calculated column I try to add to my model is quite simple. It is just a SWITCH function involving another column and a measure. It works if I replace the code in an existing column but doesn't work if try to use in a new column. 

Thank you for the help.
