Refreshing a report in the Service after making changes in desktop

Hello PaisleyPrince,
Thank you for reaching out to the Microsoft Fabric Forum Community.

To make changes in Power BI Desktop without refreshing the data there and only refresh after uploading to the Power BI Service, you can follow these steps:

• Open your report in Power BI Desktop and make the necessary changes to the query in Power Query Editor.
• Avoid triggering a refresh by not clicking "Apply & Close" or "Refresh Preview" while editing. Instead, save the file (File > Save) after changes.
• To minimize automatic evaluations, set the "Maximum number of simultaneous evaluations" to 1 under File >> Options and Settings >> Options >> Data Load >> Parallel loading of tables. This force queries to evaluate one-by-one and check the "Maximum memory used per simultaneous evaluation" is adequate for your queries.
• Save the .pbix file and click Publish to upload the updated report and dataset to the Power BI Service. This will not trigger a refresh in Desktop.
• In the Power BI Service, go to the dataset settings, ensure the Business Central API credentials are correctly configured under Data source credentials, and trigger a manual refresh or rely on your scheduled refresh.

If the timeout error continues, please check the refresh history in the Power BI Service for detailed error messages and share them here. This will help us provide more targeted assistance.
