Always get an error when creating Analytic view on GROUP BY clause

Dear All,

I am using the AWS SAP NW AS ABAP & SAP BW 7.4 SP8 on HANA1.0 SP8 Developer system.

I am going through tutorials and every time I create an Analytic view (with a Data Foundation Fact Table) and an Attribute Dimension whenever I specify a Measure (defaults to Sum Aggregation) I always get (have tried building several analytic views) and after activation and then attempting a Data Preview of raw data I always get the error:

Error: SAP DB Tech JDBC:[260]

The column <an attribute column> is invalid in the select list because the GROUP BY clause or an aggregation function does not contain it.

When I look at the generated SQL I see the SELECT of the columns and the sum of the measure but NO GROUP BY statement. I have tried several tutorials and follow them exactly but on the data preview I get the above error.

Please could you put me out of my frustration and suggest what the cause for this error is.

Thanks

Mark Dean
