Input Parameter with no Value

Input Parameter with No Value

Issue:

I have input parameter IP_Div. If I input division value? I get out put in HANA data preview. If I decide to leave input parameter blank and expect retrun results for all divisions, I don’t get any record. It seems it does not like me leaving input parameter blank.


Please see attached screen to see how input parameter filled returns value but leaving it blank does no return any value.

But When I Want to leave it blank to see data for all divisions? I don't get any records.

    Hello Faisal,

    I think you have "just" a simple filter expression which compares your parameter IP_Div against your Division column. In case of an empty division parameter that filter expression is not ignored and all values are filtered out, cause no one is blank.

    To get your values you have to adjust your filter expression, to consider that case. For instance like following:

    if('$$IP_Div$$' = '',match("Division",'*'),match("Division",'$$IP_Div$$'))

    I used "Division" as your column name (if you renamed it for the output please adjust it to the name you have available in the data source).

    Regards,
    Florian

    Hi Florian, if we have input parameter with multiple input values? then will we need to change else condition with "In" instead of Match?
