Hello,

I do not see any restriction or configuration in the How To. Is it impossible to update a Power BI desktop model?

I get the following error:

Thank you

Hi, there is work that needs to be done ("Desktop hardening") for Power BI Desktop to safely allow external model changes beyond what is documented here:
https://docs.microsoft.com/en-us/power-bi/create-reports/desktop-external-tools#supported-write-operations
This of course only applies if the dataset is the Desktop hosted one.

@BAAAASS : Please read the article thoroughly. The article explicitly says this:

Data modeling limitations
All Tabular Object Model (TOM) metadata can be accessed for read-only. Write operations are limited because Power BI Desktop must remain in-sync with the external modifications, therefore the following operations are not supported:
Any TOM object types not covered in Supported write operations, such as tables and columns.
...

So, until Power BI Desktop hardening activities are completed, no external tool can perform write operations to tables and columns in a Power BI Desktop file.
