SAP HANA db: "COUNT DISTINCT" does not return correct value for CalcView

You model "COUNT DISTINCT" in a Calculation View and the result of a statement does not return the correct result for "COUNT DISTINCT" using the Calculation View
Due to a programming error the result of "COUNT DISTINCT" of an Calculation View is wrong under certain circumstances

Prerequisites:

    1. SAP HANA database Revision 10 or later

    2. The statement, which uses the modeled "COUNT DISTINCT" on a Calculation View, has both of the following constraints:

        a) the statement contains a WHERE-Clause having an operator, which is NOT "EQUAL" or uses "OR" to connect several WHERE conditions

        b) the column of the WHERE-Clause is not part of a "GROUP BY" of the statement


SAP is working on a solution asap.

Workaround: Check whether it is possible to add a "GROUP BY" with the column of the WHERE-Clause to your statement
