hi,

i wanna to show the fields column on the basis of the selection criteria,suppose i m selecting range 1 to 3 in select option then it should show only three bom coloumn records. since i m getting the 8 bom column header from one stko table , and i m applying the condition in select query on heading of that column headings that is coming by sap.but it is not working and showing all fields column.

note ===> column header is coming from sap table stko.

OK jus tell me how i can hide the column on the basis of selection criteria. well my header is coming from a database table.

Hi Vijay

I think you are asking that in the selection screen if u give a number then it should print for that range of numbers only. Is it ur requirement.....

Just go through this report in which i had set adefault value to 50 it will show u the range for 50 only like this u can restrict for any number

To Hide a statement in alv u have to write a statement as

chk these 2 options in fieldcatalog

<b>

NO_OUT</b>

If you set this field, you hide the relevant column in the list. Nevertheless, the column is available in the field selection and can be interactively selected by the user as a display field. The ALV displays the contents of hidden fields on the detail screen for a row in the grid control.

wa_fieldcat-no_out = 'X'.

<b>

TECH</b>

If this field is set, the relevant field is not displayed on the list and cannot be shown interactively. The field is only known in the field catalog. (For example, it must not be specified as a sorting criterion).

wa_fieldcat-tech = 'X'.

Hi,

do like this after creating the field catalog.(this is for changing the column text)

field-symbols:<lfs_fieldcat> type slis_fieldcat_alv.

LOOP AT FCAT ASSIGNING <lfs_fieldcat>.

<lfs_fieldcat>-FIELDNAME = 'ur field'.

<lfs_fieldcat>-seltext_m = 'ur text'.

ENDLOOP.

this is for hiding the columns.

data:num type sy-index.

select-options:range for num.

after creating the fieldcat.

LOOP AT FCAT ASSIGNING <lfs_fieldcat>.

if sy-index inrange.

<lfs_fieldcat>-no_out = 'X'.

endif.

ENDLOOP.

reward all helpful answers.

rgds,

bharat.
