Do you want to happen this after output or with in the program logic.

If it is after output display -> Set the field catelog NO DISPLAY field to 'X' in designing the same. Based on the Lay out selection you can pull them into the Layout

If it is in the programming logic i am not sure?

Hi,

If you wanna create dynamic structure based on the condition you have to go with field symbols. Probably you can achieve in that way

using NO_OUT or TECH options of the Fieldcatalog you can Hide the Fields from display.

Check it once.

FIELDCAT-NO_OUT = 'X' .  "<----This Hides the field
or

FIELDCAT-TECH = 'X'. "<-----_THis Completely Excludes from the layout.

Hello Bhaskar

My general approach to ALV programming is to display as much information as possible (within the requirements). If the users only need partial "views" of the list then they are free to use the standard functions of ALV to rearrange or hide superfluous columns.
