Parameters Handle NULL VALUES

Hello Developers,

I have some parameters that is of type Number. I want to pass NULL into it but we can only pass NULL values to the parameter which is of type String.

The parameters are coming from BE and I cannot change it. I tried to create a sub-report and use a formula to handle it. But couldn't figure it out.

Thanks,

Preethi.

    Hi Preethi,

    Make the prompt optional and use the HasValue() function along with it.

    Hi Preethi,

    First of all will that BE prompt allow you to pass NULL value ?

    You can create a sub report with a formula or a string type parameter (optional) which can accept NULL value. But you can't join / link this with sub report parameter.

    Best way is to mask that parameter like :

    Create a blank report -- Insert Main report as sub report--

    Now in blank report create a formula with numeric value with 0 (zero) and pass this to BE parameter.

    Crate a string parameter at sub report (Main report earlier) and make it optional. This parameter can be compared with your database fields and can pass NULLs.

    Thanks,
