SSRS-Datasource won't change when reupload report

Question

I got a report with 2 data sources and both are Shared Data source. I am trying to change both of them to Custom Data Source but when I re-upload the report in my Report Manager, it won't work.

Edit: I don't have an error because the report successfully uploads, but the data source doesn't change. If I have a field in the report, the report shows the new field, but the data source stays the same.

Answer 1

Is there an error message? It won't work could be a bunch of things. I'd upload a picture of the error or whatever screen you can't get past. Let me know when you can do that, then it will be easier to troubleshoot. If you can't upload an image than I would:

1. Check your datasource connections are correct.
2. Check your datasets are using the correct connection.

Answer 2

This might be because of caching that SSRS does with the datasource for the report on the server. Do the new datasources have the same name as the old ones?

You could create the custom datasources in the DataSources tab in the Manage menu for the report in the report manager.

To do this open up the Report Menu by click on the "..." then selecting Manage

Then click on the Data Sources Tab, then change the data source to Custom Datasource.

Then set up the datasource like you did in the report, you will need to select SQL Server for the Connection, add the connection string and choose the authentication type which in the image below is windows authentication but I am not sure how it is set up on your server. Then click Test Connection. Then Click Save (make sure you click Save before navigating away).

Or you could delete the old report in the report manager and then upload it again. Note that deleting the report will delete any schedules and other customization you have done ie. Name and Description.

This is a setting thats controlled from the deployment properties of the visual studio SSRS project. Right click the project name and select Properties. Then from the Property section of the general page notice "Overwrite Datasets" & "Overwrite Datasources". Change the one that's necessary and re-deploy to see it updated in the report portal.
