ALV GRID display

Dear all,

pls suggest me for the below issue.

requirement is as follows:

ALV grid contains 4 columns for example, a, b, c, d.

the titles of these 4 columns should come from data element field label (i.e. from Heading). but currently it is taking 'short field label' of the data element. but i want 'field label (i.e. heading) of the data element.

for example the 4 field names from the table z_yt2_formul is:

1. SPRAS

2. VORLAGE

3. TITEL

4. TEXT

current code is as follows:

DATA: lt_form TYPE TABLE OF z_yt2_formul,

PERFORM alv_process TABLES lt_form.

FORM alv_process TABLES pt_form STRUCTURE z_yt2_formul.

DATA: ls_form TYPE z_yt2_formul.

DATA: lt_fieldcat TYPE TABLE OF slis_fieldcat_alv,

lt_events TYPE slis_t_event,

ls_layout TYPE slis_layout_alv,

lv_repid(40) TYPE c.

DATA: lv_start_line TYPE i VALUE '8',

lv_end_line TYPE i,

lv_tfill TYPE sytfill.

DATA: lt_excl TYPE slis_t_extab.

Hi Venkat,

Try to give the program inside code format which will be easy to read.

Well, check the changes needed in PREPARE_FIELDACAT subroutine for your requirement


FORM prepare_fieldcat TABLES pt_fieldcat STRUCTURE gs_ref_fieldcat.

DATA: ls_cat TYPE slis_fieldcat_alv.

LOOP AT pt_fieldcat INTO ls_cat.
CASE ls_cat-fieldname.
WHEN 'SPRAS'.
ls_cat-just = 'C'.
ls_cat-outputlen = 4.
ls_cat-col_pos = 1.
ls_fcat-seltext_l  = ls_cat-reptext_ddic.
ls_cat-ddictxt    = 'L'.

MODIFY pt_fieldcat FROM ls_cat.
WHEN 'VORLAGE'.
ls_cat-outputlen = 25.
ls_cat-col_pos = 2.
ls_fcat-seltext_l  = ls_cat-reptext_ddic.
ls_cat-ddictxt    = 'L'.

MODIFY pt_fieldcat FROM ls_cat.
WHEN 'TITEL'.
ls_fcat-seltext_l  = ls_cat-reptext_ddic.
ls_cat-ddictxt    = 'L'.
MODIFY pt_fieldcat FROM ls_cat.
WHEN 'TEXT'.
ls_fcat-seltext_l  = ls_cat-reptext_ddic.
ls_cat-ddictxt    = 'L'.
MODIFY pt_fieldcat FROM ls_cat.
WHEN OTHERS.
DELETE pt_fieldcat.
ENDCASE.
ENDLOOP.

ENDFORM. " PREPARE_FIELDCAT

Hope this will work

Cheers,

Hi,

Try this.

Loop at it_fieldcat.

it_fieldcat-ddictxt = 'L'. "Always Long description

MODIFY it_fieldcat.

CLEAR it_fieldcat.

endloop.

Hope this will help.

Thanks,

Kishore
