'(404) Not Found' error when trying to load data to Power BI

APPLIES TO: FluentPro Power BI reports package for Planner; FluentPro Power BI reports package for Project Online


Following the steps to create a report in Power BI desktop using FluentPro Power BI package user receives an error  '(404) Not Found'.

Such error may occur on the step, when user chooses an OData feed as a data source, provides the User Name and Password for authentication and clicks 'Connect' 

Power Bi Desktop will attempt to load the data, connecting to the provided OData feed URL with the provided credentials.

Instead of the data being loaded, user receives an error - 


The error message most frequently occurs due to the provided user account credentials not being valid.

Power BI reports built with the help of FluentPro Power BI packages use DataMart OData as data source. In other words, Power BI extracts data from DataMart OData and loads it to the report. To establish connection between Power BI and DataMart OData Basic type of authentication is required - login and password.

If either of integrated authorization modes were used - Office 365, Google or Microsoft - when signing up to DataMart, it would not be possible to establish connection between Power BI and DataMart OData, since for such authentications user's login and password are not used explicitly. They use access tokens instead.


I. Generate a password for your account in DataMart

If you signed up to DataMart using either of integrated authorization modes - Office 365, Google or Microsoft, you can still use your user account, however you would need to set a password for this account in DataMart:
