Not able to delete a column in Table in webdynpro

[Former Member]

Hi All,

I am enhancing 'HRRCF_C_SEARCH_UI' dynpro of erec and want to hide country & reference code column in view VW_UNREG_HITLIST.

I tried using CALL METHOD LR_TABLE->REMOVE_COLUMN in wodomodifyview in post-exit, but it is not working.

Please help me.

Hi,

try with below coding

data : gs_table type ref to cl_wd_table,

         gs_abs_column type ref to cl_wd_abastr_table_column.

gs_table ?= view->get_element( id = 'TABLE' ). "Table ID

call method gs_table->remove_column

exporting

id = 'REF_CODE'

index = 1

importing

the_column = gs_abs_col.

Hi,

use remove_grouped_column() method to achieve this.

Code snippet:

DATA: lr_table    TYPE REF TO cl_wd_table,
       lr_abs_col TYPE REF TO cl_wd_abstr_table_column.

lr_table ?= view->get_element( id = 'TABLE ). " ID of Table UI

     CALL METHOD lr_table->remove_grouped_column
       EXPORTING
         id                = 'COL1' " column
         index             = 1      " index
       RECEIVING
        the_grouped_column = lr_abs_col.

hope this helps u,

Hi Kiran,

I tried the code mentioned by you, but it is giving error.

Runtime Errors         OBJECTS_OBJREF_NOT_ASSIGNED

Exception              CX_SY_REF_IS_INITIAL

Detail:

You attempted to use a 'NULL' object reference (points to 'nothing')

access a component (variable: "LR_TABLE").

An object reference must point to an object (an instance of a class)

before it can be used to access components.

Either the reference was never set or it was set to 'NULL' using the

CLEAR statement.

Hi,

Please see in ST22 the error details. As mentioned in coments in the code, you need to replace the ID (TABLE) to your ID name of table in view layout. and the column name too..

I guess you didn't change those.!!

If not, please post the dump details of ST22

Hi Kiran,

        the_grouped_column = lr_abs_col.

Its showing error on Call method statement.

Hi,

Seems, lr_table is Initial here!! Please keep a break point at Call Method statement and check that lr_table has reference or not. And please make sure the table ID is JOB_HITS in the Layout

Edit: I see that the Id of the table is 'TABLE' in the view VW_UNREG_HITLIST, so please change it

Your code should be as below:

lr_table ?= view->get_element( 'TABLE' ).
CALL METHOD lr_table->remove_grouped_column
       EXPORTING
         id                = 'TABLE_COUNTRY_TXT' " column
         index             = 3      " index
       RECEIVING
        the_grouped_column = lr_abs_col.

hope this helps,

Hi

Try with below coding

lr_table ?= view->get_element( 'TABLE' ).

CALL METHOD lr_table->remove_grouped_column

       EXPORTING

         id                = 'TABLE_COUNTRY_TXT' " column

         index             = 3      " index

       RECEIVING

        the_grouped_column = lr_abs_col.

if wrong correct me.

Hi Kiran,

I rectified the mistakes that you told, the method remove_grouped_column was not working but method REMOVE_COLUMN worked.

Thanks for your support.
