Hi All,

As per my requirement, I have created the Cube with Union node

Step1: let us consider two facts table shop_facts and promotion facts and this projection are joined union node

mapping with many to 1 relationship in target and few columns are mapped with 1:1 (source and Target )
issue; when the source column mapped one to one target data is populating the null values which are representing the symbol (?) the null values should replace with values Siva

Step2: This is method has developed to get my expected results

Step3: How to avoid null values when I'm trying to case condition at projection 3 getting error error.jpeg

    The CASE expression is not supported within a calculated column.

    In SQL mode you can try if the COALESCE function is supported (guess not):

    COALESCE("MARGIN", 'ram')

    If it is not supported you can switch to a calc. engine expression and use the IF and ISNULL functions:

    IF(ISNULL("MARGIN") = 1, 'ram', "MARGIN")
