Hello Preet,

For creating the Field catalog

  • Internal table for Field Catalog

DATA: G_T_FIELDCAT_C TYPE LVC_T_FCAT,

G_R_FIELDCAT TYPE LVC_S_FCAT.

FORM BUILD_FIELD_CATALOG .

DATA: L_F_COUNT TYPE I VALUE '0'.

*/ Add properties values to ALV Catalog

ADD 1 TO L_F_COUNT.

PERFORM ADD_CATALOG USING 'MTART' 'C' SPACE L_F_COUNT "Sales Org

TEXT-005 4 SPACE SPACE SPACE.

ADD 1 TO L_F_COUNT.

PERFORM ADD_CATALOG USING 'VKORG' 'C' SPACE L_F_COUNT "Sales Org

TEXT-001 4 SPACE SPACE SPACE.

ADD 1 TO L_F_COUNT.

PERFORM ADD_CATALOG USING 'MATNR' 'C' SPACE L_F_COUNT

TEXT-002 18 'MATN1' SPACE SPACE.

ADD 1 TO L_F_COUNT.

PERFORM ADD_CATALOG USING 'STAWN' 'C' SPACE L_F_COUNT

TEXT-004 13 SPACE SPACE SPACE.

ENDFORM. " build_field_catalog

FORM ADD_CATALOG USING P_FNAME

P_INTTYPE

P_KEY

P_COL_POS

P_COL_TEXT

P_INTLEN

P_CONV

P_EDIT

P_HOTSPOT.

CLEAR G_R_FIELDCAT.

G_R_FIELDCAT-FIELDNAME = P_FNAME.

G_R_FIELDCAT-INTTYPE = P_INTTYPE.

G_R_FIELDCAT-KEY = P_KEY.

G_R_FIELDCAT-COL_POS = P_COL_POS.

G_R_FIELDCAT-COLTEXT = P_COL_TEXT.

G_R_FIELDCAT-OUTPUTLEN = P_INTLEN.

G_R_FIELDCAT-CONVEXIT = P_CONV.

G_R_FIELDCAT-EDIT = P_EDIT.

G_R_FIELDCAT-HOTSPOT = P_HOTSPOT.

APPEND G_R_FIELDCAT TO G_T_FIELDCAT_C.

ENDFORM. " add_catalog

If useful reward.

Hi,

You can do in two ways.

one is 


DATA: IT_FIELDCAT  TYPE  LVC_T_FCAT,
      X_FIELDCAT TYPE LVC_S_FCAT.
DATA: L_POS TYPE I.
  L_POS = L_POS + 1.


  X_FIELDCAT-SCRTEXT_M = 'Delivery'(024).
  X_FIELDCAT-FIELDNAME = 'VBELN'.
  X_FIELDCAT-TABNAME = 'IT_FINAL'.
  X_FIELDCAT-COL_POS    = L_POS.
  X_FIELDCAT-NO_ZERO    = 'X'.
  X_FIELDCAT-OUTPUTLEN = '10'.
  X_FIELDCAT-HOTSPOT = 'X'.

  APPEND X_FIELDCAT TO IT_FIELDCAT.
  CLEAR X_FIELDCAT.
  L_POS = L_POS + 1.

  X_FIELDCAT-SCRTEXT_M = 'Item'(025).
  X_FIELDCAT-FIELDNAME = 'POSNR'.
  X_FIELDCAT-TABNAME = 'IT_FINAL'.
  X_FIELDCAT-COL_POS    = L_POS.
  X_FIELDCAT-OUTPUTLEN = '5'.
  APPEND X_FIELDCAT TO IT_FIELDCAT.
  CLEAR X_FIELDCAT.
  L_POS = L_POS + 1.

another is

create the structure in SE11 with all the fields from 3 tables and then pass it to the FM.

using the function, 

  call function 'LVC_FIELDCATALOG_MERGE'
       exporting
            i_structure_name = 'ZSTRUC'
       changing
            ct_fieldcat      = pt_fieldcat.

Hello Preet

If you have the structure for you ALV list already defined in the DDIC then use the name of structure to receive the fieldcatalog from LVC_FIELDCATALOG_MERGE.

However, if you haven't defined a DDIC structure but use a type defined within your program you can still use function module LVC_FIELDCATALOG_MERGE. Simply call the function module with your 3 different tables and collect the fieldcatalog into the same itab (e.g. gt_fcat). Then remove all unnecessary fields and duplicates and, if necessary, re-order the remaining fields.

* First sort the fields in the catalog in the required order
* Then renumber them.
  LOOP AT gt_fcat INTO ls_fcat.
    ls_fcat-col_pos = syst-tabix.
    MODIFY gt_fcat FROM ls_fcat.
  ENDLOOP.

Regards

Uwe
