ALV Object Model

Former Member — Fri, 30 Dec 2005 04:45:28 GMT

Hi,

In earlier version, to make a column editable, I used to change field edit of structure catalog to be X. How should I do the same in while using ALV Object Model.

In addition to that, SAVE button is disabled, how should I enable it.

Thanks,

Anuranjan

Hi,

Set the PF-ststus in PBO, and enable the save button by giving some function code to that.

and in objects fieldcat-edit = 'X'.

normal fieldcat-input = 'X'.

MODULE PBO OUTPUT.

  SET PF-STATUS 'MAIN100'.
  SET TITLEBAR 'MAIN100'.

ENDMODULE.                    "PBO OUTPUT

i hope you create the screen and container, if so in the module PBO you need to set the status and enable save,back, what ever you required...

Hi.

Using cl_salv_columns . It's not ALV, it's SALV .

An excerpt:

Before the introduction of the ALV OM, you would create a Field Catalog to manipulate the number of columns and/or the settings for these columns Now there is an OO approach to this where you ask the ALV OM for a Columns Object (cl_salv_columns) and manipulate through it. The standard implementation of this method exposes all columns and sets the optimize width. This method can be redefined to create custom column processing.
