About parameters in selection screen

[Former Member]

When it if select-option,when the value of low and high are initial,it will select all the items,and if the low and high value are not initial,it will select items in this range.

I just think if abap have this for a parameter ,like when it is initial,it will select all items,and when it is not initial,it will select the item which some field = this parameter.

thanks a lot!

hi,

if parameter is empty, it will try to select records where the field is empty in the DB. So it is NOT like select options...

hope this helps

To keep it simple why Parameters do not behave the same way as SELECT-OPTIONS when initial is, with parameters it always looks for EQUALITY of value whereas with SELECT-OPTIONS value we can use other relational operations like EQUALITY, EXCLUDING, GREATER THAN... Hope that clarifies...

Here you have to display the selct-option which will appear as a parameter on the selection screen and user can enter only one value as in a parameter.

select-options: s_para for mara-matnr no-extension
                                       no intervals.
