Remove a column using CL_SALV_COLUMNS_TABLE class

Former Member — Thu, 12 Jul 2007 22:19:23 GMT

Hi Gurus,

I have a problem using CL_SALV_COLUMNS_TABLE class. I need to remove a colum from the report output and the method that i think it could help me is REMOVE_COLUM. However, this method is protected.

An alternative soluction is to use the method SET_VISIBLE from class CL_SALV_COLUMN, but in this way i cannot eliminate the colum and that is my necesity.

¿Can you help me with this?

Thanks

Hi,

I am not sure of an other method..

You can try this..

Create a local class in you program and inherit the class CL_SALV_COLUMNS_TABLE ...

In the new class create a method ..

In the new method..call the protected method using the object ME

Ex..

CALL METHOD me->remove_column

.............

Now in your program create an object for your local class and call the method you created..

Thanks

Hi Naren,

Finally i can use the method REMOVE_COLUMN thanks to your answer.

However, my problem continue. I used the method GET_COLUMNS from CL_SALV_TABLE class to obtain all columns that belong to the internal table that contain the data to be display in the report. It returned an instance from CL_SALV_COLUMNS_TABLE. I need to link the object that i instantiated from the local class to the object which contains the name of all columns in order to delete from the columns table the column that i don´t need.

Thanks for your help, excuse me if my question is a little complicated.

Hi,

I think I understood your question..

When you create an object for the local class(that you inherited the CL_SALV_COLUMNS_TABLE )..That will be your main object to do all the operations..Use this object to remove the columns and call the methods that is available in the class CL_SALV_COLUMNS_TABLE..

Do not create another instance for the class CL_SALV_COLUMNS_TABLE again..

Hope I understood your question..

Thanks

Hi Andres, please use the method SET_TECHNICAL, this should remove your column. For an example, see any program which starts with SALV

Here is a complete example of what I mean.



REPORT zrich_0001.

DATA: ispfli TYPE TABLE OF spfli.

DATA: gr_table TYPE REF TO cl_salv_table.
DATA: gr_columns TYPE REF TO cl_salv_columns_table.
DATA: gr_column TYPE REF TO cl_salv_column_table.
DATA: gr_functions TYPE REF TO cl_salv_functions.

START-OF-SELECTION.

  SELECT * INTO TABLE ispfli FROM spfli.


  cl_salv_table=>factory(
    IMPORTING
      r_salv_table   = gr_table
    CHANGING
      t_table        = ispfli ).

  gr_functions =  gr_table->get_functions( ).
  gr_functions->set_all( abap_true ).

  gr_columns = gr_table->get_columns( ).
  gr_column ?= gr_columns->get_column( 'MANDT' ).
  gr_column->set_technical( abap_true ).

  gr_table->display( ).

Hi Narendran ,

CL_SALV_COLUMNS_TABLE is a final class. So it will show a syntax error.

So could you please suggest.

Thanks.
