Hide command in ABAP Objects

[Former Member]

Hi everybod,

i got a small Problem with the HIDE command in ABAB Objects. I got a Method called

write_on_screen( ). in this method i got code like this:

DATA:
    test TYPE c.

test = 'Hello'.

WRITE: /0 sym_minus_folder AS SYMBOL HOTSPOT.
WRITE: /5 'Im a dummy line'.
HIDE test.

Then i got this message "You cannot use HIDE with a local field."

If i change the code like this

WRITE: /0 sym_minus_folder AS SYMBOL HOTSPOT.
WRITE: /5 'Im a dummy line'.
HIDE _test.

_test is an Attribute of the class with the type c. "HIDE is not supported with the attributes of classes. "

Maybe someone got an advice for me.

Greetings

Hello Moritz

The error messages are quite clear: the field used for the HIDE statement must be a global variable of your report and cannot be part of your ABAP class.

Why?

The hidden fiields will only be processed within the list-processing (e.g. you double-click on a row on WRITE your list). Obviously you cannot link this list-processing event to your ABAP class (e.g. using an event handler method).
