here I am using the SAP standard structure so I can use merge FM .. if you develop ur own structure or internal table, it would be better to declare you field with like ..

data: begin of itab

vbeln like vbak-vbeln

it's better to prepare your fieldcatalog yourself i.e. not using the FM.

DATA: FLDCAT TYPE SLIS_T_FIELDCAT_ALV,

WA_CAT TYPE SLIS_FIELDCAT_ALV,

PERFORM POPULATE_FIELDCAT USING:

• 'IT_VBAK' 'BOX' ' ' ' ' ' ' ' ' ' ',

• 'IT_VBAK' 'LIGHT' '01' 'LIGHT' ' ' ' ' ' ',

'IT_VBAK' 'VBELN' '01' 'SALES_ORDER' 'X' 'X' ' ' ' ',

Hi,

Fcat merge: Preparing the display format like column preferences and descriptions etc....

U can activate a lot of options like sum, variants etc...

1)Suppose u have itab with fields one two three with same discriptions(DDIC). U want to display as is then u can use following process.

Use REUSE_ALV_FIELDCATALOG_MERGE function module.

It will display as is order and descriptions from DDIC.

2)U want to display order as three(3) one(1) two(2) and desc as is then u can use following process.

populate fieldcat manually. like

x_fieldcat-col_pos = lc_pos.

x_fieldcat-tabname = lc_tabnam.

x_fieldcat-fieldname = lc_field2.

x_fieldcat-seltext_l = text-002.

APPEND x_fieldcat TO i_fieldcat.

Hi

A field catalog is prepared using the internal table (I_FIELDCAT) of type SLIS_T_FIELDCAT_ALV. Field catalog containing descriptions of the list output fields (usually a subset of the internal output table fields).

When compared to use the FM "REUSE_ALV_FIELDCATALOG_MERGE",manual developement of Fieldcatalog is better.In manual development we can gv colors,sizes and etc.These r not possible by using FM.

e.g.

FLDCAT-FIELDNAME = 'VBELN'.

FLDCAT-SELTEXT_M = 'Sales Document'.

FLDCAT-COL_POS = 0.

*FLDCAT-EMPHASIZE = 'C411'.

FLDCAT-OUTPUTLEN = 20.

FLDCAT-KEY = 'X'.

*FLDCAT-NO_OUT = 'X'. "It hides the field from display

APPEND FLDCAT TO FLDCAT.

CLEAR FLDCAT.

FLDCAT-FIELDNAME = 'ERDAT'.

FLDCAT-SELTEXT_L = 'Record Date created'.

FLDCAT-COL_POS = 1.

FLDCAT-KEY = 'X'.

FLDCAT-JUST = 'R'. "Right(R)/Left(L)/Center(C) Justification

APPEND FLDCAT TO FLDCAT.

CLEAR FLDCAT.

FLDCAT-FIELDNAME = 'ERNAM'.

FLDCAT-SELTEXT_L = 'Cteated Object Person Name'.

FLDCAT-COL_POS = 2.

APPEND FLDCAT TO FLDCAT.

CLEAR FLDCAT.

fell free to ask,if u hv any doubts regarding ALV's

award points if it is useful.

Thank you
