Reproducing the Issue

  1. Go to the Business Analytics Work Center.
  2. Click Design Data Sources under the Data Sources sub view.
  3. Search for any financial data source, for example, Fixed Assets and individual Materials Values and click the Preview button.
  4. Click GO.
  5. You will receive one or more of the above errors.


For financial data sources, parameters such as Company/Set of Books/Fiscal Year Variant/Key Date etc.. are mandatory.

When a financial data source is previewed in Business Analytics these mandatory selection parameters are not applied and in return the data source will not fetch any data.


As financial data sources cannot be previewed it is best practice to check in the Design Reports section of Business Analytics if there is a report based on the data source you want to preview.

They are available in list of data sources in Business Analytics only to be reused in custom data sources/custom reports.
