Cannot initialize report- SCOM 2022 UR6, SSRSv16.0.8564.33454

Question

Everything worked until a week ago. No changes made to system. These reports were working fine, so well that I created Scheduled Reports for a few of our customers. I have since disabled/removed them.

Reports with issues:

Reporting\Microsoft Generic Report Library/Availability,Alerts,Health,Most Common Alerts,Most Common Events and others,

Reporting/Microsoft Data Warehouse Reports/Data Warehouse Availability

Data Warehouse Main:

<DataSourceDefinition>

<Extension>SQL</Extension>

<ConnectString>data source=SQLSERVER\scom;initial catalog=OperationsManagerDW;Integrated Security=SSPI</ConnectString>

<UseOriginalConnectString>False</UseOriginalConnectString>

<OriginalConnectStringExpressionBased>False</OriginalConnectStringExpressionBased>

<CredentialRetrieval>None</CredentialRetrieval>

<Enabled>True</Enabled>

</DataSourceDefinition>

Hi,

It sounds like you're encountering an issue with System Center Operations Manager where a report cannot be initialized due to a null value in the GroupList parameter.

This error can occur for several reasons, but here are a few steps you can try to resolve it:

1. Ensure that the data source for the report is correctly configured. You can do this by navigating to the Reporting Services Configuration Manager and verifying the settings for the data source.
2. Make sure that the GroupList parameter is not empty or null. This parameter should contain a valid list of groups that the report needs to process.
3. Check the SCOM and SSRS logs for more detailed error messages. These logs can provide additional insights into what might be causing the issue.
