Hello,
I would like to give the possibility to the users to change the format of the columns on a report based on a Daset already prepared.
What I have found out is that only possibile to change the format of a column by preparing a new measure on that field.
Isn't a way for allowing users to change the date format of a dateset when they are preparing the report?
Thanks

Hi @thebigwhite,
A column format string is a hardcoded property at the tabular model level.
A report builder, using a live connection, cannot change it directly.
You have a couple of options:
1. Use DirectQuery for Power BI datasets and Azure Analysis Services to connect to the dataset, instead of a live connection. This will create a local model with metadata that can be changed- So a report builder will be able to set a different format string. Note that this capability is in preview and has limitations. It also complicates your solution and has other drawbacks.
2. Set a date format with an asterisk- Those will change the end-user display based on its regional settings.
