How to restrict column in alv

hi experts,
as we all know alv have 90 column , but we i want to restrict column i.e report should allow 30 column , if we want to add 31st column it should give restriction mesage or it should not allow to add column, can anyone tell me how to code this query.
thank in advance,
Ashish

Ashish,
I guess you can use this FM REUSE_ALV_FIELDCATALOG_MERGE which will give an internal table with all the columns created from an internal table or structure.based on that you can display a message if columns count exceeds
Thanks

How to restrict columns in Advanced search which are known at runtime

Hi Team,
I need your suggestions for one of my adf search usecase. I had Querypanel with table on UI...where in Viewobject has relations with 2 other tables and this Viewobject is based on Entity...now in advanced search for addfields i was getting all column names by default like 3 tables column names....instead of all columns i need to restrict to particular columns. This particular columns will be decided at runtime like how many columns needs to be shown and alias names for those particular columns. So could you please help me how to approach this requirement.
Thanks in Advance for your help.

whatever you said is at designtime wherein we can uncheck the Queryable checkbox....but as i said at runtime from the application i can come to know whichever fields needs to be there and alias names for columns for add fields in Advanced search...

How to hide columns in ALV? (via cl_salv_table)

Dear forumers,
Is there a way for me to hide a few columns (or data fields) from being displayed in the ALV table, using the cl_salv_table method?
FORM display_data_alv .
TRY.
      CALL METHOD cl_salv_table=>factory
        IMPORTING
          r_salv_table = o_table
        CHANGING
          t_table      = i_ro_assets.
    CATCH cx_salv_msg.
ENDTRY.
o_functions = o_table->get_functions( ).
o_functions->set_all( abap_true ).
o_columns = o_table->get_columns( ).
o_columns->set_optimize( abap_true ).
PERFORM set_columns.
o_events = o_table->get_event( ).
CREATE OBJECT o_handle_events.
SET HANDLER o_handle_events->on_double_click FOR o_events.
o_table->display( ).
ENDFORM.                    " DISPLAY_DATA_ALV

    CATCH cx_salv_not_found.
ENDTRY.
ENDFORM.                    " SET_COLUMNS
I have also tried to exclude some columns from the subroutine SET_COLUMNS, but they are still showing in the resulting ALV table. What can I do here next?
Appreciate any help here.
Thanks very much.

You can use the method SET_COLUMN_TECHNICAL of the class CL_SALV_COLUMN to hide the Column.
data:
ir_columns type ref to cl_salv_columns_table,
lr_column type ref to cl_salv_column.
try.
      lr_column = ir_columns->get_column( 'MANDT' ).
      lr_column->set_technical( if_salv_c_bool_sap=>true ).
    catch cx_salv_not_found.                            "#EC NO_HANDLER
endtry.
Check the report SALV_DEMO_TABLE_COLUMNS to know more about the Column processing in SALV model.

How can we restrict Column length in ALV using POWL.

I browsed a lot for getting the solution for this, Can any one help me out from this issue.

How can i suppress columns in ALV ?? Will reward points.

Hello Gurus, how can i suppress column in ALV when i`m using the transparent table:
CALL METHOD grid->set_table_for_first_display
      EXPORTING
        i_structure_name = 'ZIANEXE'
        is_layout        = wa_layout
        is_variant       = wa_variant
        i_save           = 'U'
        IT_TOOLBAR_EXCLUDING = LT_EXCLUDE
      CHANGING
        it_outtab        = itab[]
        it_fieldcatalog = fieldcat.
Please help.

in the fieldcatalog you are providing there is a field NO_OUT use this.
Loop over internal table and check fieldname. If fieldname = column you want to hide, NO_OUT = 'X'.
