HANA Calculation view Union giving more records than source nodes, few records are Duplicated

[former_member626054]

Hi Experts,

I am facing an issue with HANA calculation view "UNION" Node. I have a HANA calculation view with 2 joins say, Join_1 and Join_2 . In data preview, I see both giving 6 records each . In next step i have a Union , say Union_1 which takes Join_1 and Join_2 as input. Now when I do data preview on the Union node, I get 16 records , 4 records extra. I was expecting 6+6 =12 records. The additional 4 records are actually duplicates . If anyone has faced this issue before can you let me know what could be the problem?

Thanks in Advance,

VM

Please check if you have joining on columns which is carrying NULL values.
