XS OData error - Cannot read property 'MEASURE_AGGREGATOR'

[isuruwarn]

Hi All,

I’m trying to write an XS OData service on top of calculation view that is defined as a CUBE (in XSA SP 12). The calc view has several aggregated columns (measures). Here is the service definition for the OData service:

service namespace "com.sap.sample" {

                "sap.sample.analytics::CVKF_TEST" as "Test"

                keys generate local "GENERATED_ID"

                aggregates always;

}

When I call this service, the whole application crashes and I get the following error message. Also, I’m unable to call any other services in this application (unless restarted):

Has anyone else come across this problem in XSA? What could be the issue here?

Thanks,

Interestingly, if you wrap the original calc view inside another CUBE calc view, the error vanishes. We are using this as a workaround for now.
