Code:
REPORT z_alv_modify_pid.
***********************************************************************
* ALV Grid Control                                                    *
* This program lists the user's Parameter-IDs, These Parameter-IDs    *
* can be modified and saved via Batch-Input                           *
*---------------------------------------------------------------------*
* Steps :                                                             *
* - Create the report Z_ALV_MODIFY_PID                                *
* - Create the Dynpro 0100 (size 27x120)                              *
* - Add OKCODE (type OK) in the element list                          *
* - Modify the flow logic of dynpro 0100 :                            *
*   * PROCESS BEFORE OUTPUT.                                          *
*       MODULE pbo_0100.                                              *
*   * PROCESS AFTER INPUT.                                            *
*       MODULE user_command_0100.                                     *
* - Create a status named 'MAIN'                                      *
*   with the buttons : SAVE BACK and EXIT                             *
*---------------------------------------------------------------------*
* The Dynpro 0100 can be uploaded                                     *
* (SE51/Change/utilities/More utilities/Upload-Download/Upload)       *
* at this URL : Z_ALV_MODIFY_PID_DYN_0100.html                        *
