ERROR: SAP DBTech JDBC: [339]: invalid number: not a valid number string

12625 Views

Good day.

I've got a problem in a calculation view.

I use a CUBE calculation view which has another Calculation view as data source.

Ive filtered 0CALMONTH through input parametrs (NVARCHAR, 6 ) in expression of my basis projection with calculation view.

Now when i try to make a Data Preview on this projection, I get this type of error:

Cannot get the data provider outline

SAP DBTech JDBC: [339]: invalid number: not a valid number string '' at function __typecast__()


When i open the calculation view, which is in projection ( which has the same filters and input parameters ) it works fine.

Any suggestions ?
