Client Connectivity Issues; Microsoft Excel And Windows Authentication - TANDBERG ANALYTICS EXTENSION Administrator's Manual

Troubleshooting
Figure 4: The "Cannot insert the value NULL into column..." bug as seen in the "Log ETL jobs"
panel.
Multiple "Error: Internal error: The operation terminated unsuccessfully."
Getting multiple Error: Internal error: The operation terminated unsuccessfully.
messages in the same ETL job indicates that there have been major changes in the TMS database
since you last ran the job (Figure 5), and that the Analytics Extension is unable to extract data
because of schema changes or changes in constraints.
These errors can occur if you have used the reconfiguration tool to replace the source database with
an entirely different TMS database. As described in Analytics Extension Reconfiguration section, the
wizard tool should not be used for such changes. To fix the problem, use the reconfiguration tool again
to return the source database to the original TMS database.

from the same failed ETL job.

Client Connectivity Issues

Microsoft Excel and Windows Authentication

Initialization of the data source failed
When connecting to a data warehouse Cube in environments where Integrated Authentication is not
available or fails, Excel will run into authentication problems. The user will not be warned about this
when creating the connection to Analysis Services and the connection will apparently be created
properly. However, later when the user tries to use the connection in a Pivot Table or Pivot Chart, the
user will get an Initialization of the data source failed error.
A workaround to the problem is appending the connection string manually:
1. In Excel, go to Data > Existing Connection.
2. Select the relevant connection, and click Open.
3. In the Import Data window that follows, click Properties...
4. Go to the "Definition" tab (Figure 6).
5. Append the text string in the "connection string" field with ";password=<your password>". Note
the semicolon in front.
