HCM Processes and Forms FPM form type

Hi,

I have a requirement where I need to allow multiple selection in a Drop Down list box in HCM processes and forms

using the FPM WD ABAP forms . I don't see a table option or ITEMlistbox . I tried with Checkbox group but I am getting

error for data inconsistent in the V_PREVIEW for the cardinality.

Do we have any alternative process in the HCM forms for selecting multiple options from the list?

Appreciate your help.

Thanks,

Lata.
