CDM 10.2.x.xxxx

Excel Data Source

Resolving the problem

Ensure that the CDM application can access the External Excel File.

For CDM 10.2.0, edit the CDM.config
For CDM 10.2.1, edit the CREDENTIALS.config

Edit the config file with a user that can access the file (ie like a domain admin or Service Acct with admin rights to where the Excel file is).

1. Navigate to the CDM installation directory: C:\inetpub\wwwroot\CognosDM-Server\Config
2. Edit the CDM.config file
3. <WindowsAuthentication>
<DataSourcesCredentials enabled="true" userName="domain\username" password="userpswd" />
<ActiveDirectoryImportCredentials enabled="true" userName="" password="" />
