    Hi,

    This can be possible in the below way but not directly....

    First you can save your alv output with required columns into a variant. First it executing the report with this variant, which means some of the fields are hidden in this variant. Then if user press that particular function button then display the report with all columns.

    Cheers,

    Bujji
