HIDE

Basic form

HIDE f.

The syntax check performed in an ABAP Objects context is stricter than in other ABAP areas. See Cannot Use Constants in the HIDE Area.

Effect

The contents of f related to the current output line are stored. If this line is selected, f is filled automatically with the stored value.

The selection can be made using:

1. AT LINE-SELECTION
   
2. AT PFx
   
3. AT USER-COMMAND
   
4. READ LINE
   
   
   

You do not have to output the field with WRITE in order to be able to store its value.

The HIDE statement does not support structures that contain tables (deep structures).

System fields that are particularly useful in interactive reporting are listed in the system fields for lists documentation.

Note

You cannot save lines or components of lines of an internal table that is addressed using a field symbol to the HIDE area. (Compare the ASSIGNING addition to the READ and LOOP statements). Assign the contents of the line or component to a global variable and save this instead.
