Hi,

You can create custom button to display the list of column names & ALV events to handle the the layout.

Try the ALV event handling in component controller,

ON_STD_FUNCTION_BEFO

ON_STD_FUNCTION_AFTE

ON_AFTER_CONFIG.

Step 1: You create a node .

Step 2: Populate the node so that it will contain list of fields in both layouts, using which you can manipulate layout in both views.

            To user display check box against each column name, so that you can identify which are the column name user has selected.

Step 3: Create a method in component controller and implement it, to enable/disable column.

Hi,

User  the interface method,

ON_CELL_ACTION - To handle the action performed by user.

ON_DATA_CHECK - will check for data change. Try to implement your code for this event in component controller, where you can get the modified records.

Hi,

Declare instance for the class CL_SALV_WD_CONFIG_TABLE.

Set the attribute. IF_SALV_WD_COLUMN_SETTINGS~T_COLUMNS

it has a class CL_SALV_WD_COLUMN for column settings using which you can freeze the column.

do the above coding in component controller.
