Enhancement Implementation - Removing columns in standard ALV table

[Former Member]

Hello Friends,

I am customizing a standard WDA Component. The business requirement is to rename couple of columns in an ALV Table.

My proposed solution is to create 2 new columns with the required names and then hide the standard columns.

I have the option to ONLY remove these 2 columns, instead of simply hiding them. I want to confirm that removing these 2 columns in an Enhancement Implementation will not permanently remove these 2 standard columns from the standard component and that these 2 standard columns will be displayed once the enhancement implementation is deleted.

Friends, Can you please confirm the same.

Regards,

John.

Hi john,

Instead of creating two new columns, you can simply change the standard column names by using below code.

• first to instantiate the alv component

DATA LO_CMP_USAGE TYPE REF TO IF_WD_COMPONENT_USAGE.

LO_CMP_USAGE = WD_THIS->WD_CPUSE_ALV1( ).

IF LO_CMP_USAGE->HAS_ACTIVE_COMPONENT( ) IS INITIAL.

LO_CMP_USAGE->CREATE_COMPONENT( ).

ENDIF.

• then get the get_model method reference to make alv change

DATA LO_INTERFACECONTROLLER TYPE REF TO IWCI_SALV_WD_TABLE .

LO_INTERFACECONTROLLER = WD_THIS->WD_CPIFC_ALV1( ).

DATA LO_VALUE TYPE REF TO CL_SALV_WD_CONFIG_TABLE.

LO_VALUE = LO_INTERFACECONTROLLER->GET_MODEL(

).

• to change the column names

DATA L_HEADER TYPE REF TO CL_SALV_WD_COLUMN_HEADER.

DATA: LO_COLUMN1 TYPE REF TO CL_SALV_WD_COLUMN.

LO_COLUMN1 = LO_VALUE->IF_SALV_WD_COLUMN_SETTINGS~GET_COLUMN( 'REQUESTID' ).

L_HEADER = LO_COLUMN1->GET_HEADER( ).

L_HEADER->SET_PROP_DDIC_BINDING_FIELD(

PROPERTY = IF_SALV_WD_C_DDIC_BINDING=>BIND_PROP_TEXT

VALUE = IF_SALV_WD_C_DDIC_BINDING=>DDIC_BIND_NONE ).

L_HEADER->SET_TEXT( 'Request ID' ).

Note: Requestid is the attribute name which you want to change the name of column.

I need to make these changes in a table NOT an ALV table. I am closing the thread.

Hi John,

If you have to add & Delete the columns,

- For addition try to use the existing coulmns & Hide the other columns which u dont want.

- Be carefull in mapping the data to the node
