Business Requirement
Develop a material master Report which displays all the fields
STEPS
Declare an internal table and work area for MARA table
Write an select statement to fetch the data
Call the function module REUSE_ALV_GRID_DISPLAY and specify the Below parameters
Structure Name
Program Name
Itab Name
FieldCatelog: It is an int.Table which contains the list of the fields to be displayed in ALV Report
It is also used to set various properties for each field.
The properties/options are:
1. COL_POS = 1.
2. FIELD NAMEÃ Specifies the name of the field
3. TABLE NAMEÃ Specifies the name of the internal table
4. SELTEXT_S Ã Specifies short
SELTEXT_L Ã Specifies Long
SELTEXT_M Ã Specifies medium
5. DO_SUM = ‘X’ Ã For grand totals
6. SUBTOT = ‘X’ Ã Sub totals to be calculated
7. EDIT = ‘X’ Ã Field can be editable
8. EMPHASIZE = ‘CXYZ’ Ã Specifies the Color to the fields
C – Indicates color
X – Color Numbers
Y – Backgroundcolor – 1 On BG color
0 off BG color
Z – Font color 1 OnFont color
0 Off font color
9. REFERENCE TABLENAME
REFERENCE FIELDNAME Ã To copy all the properties from data dictionary to a field catalog field.
10. KEY Ã Specify the key field
11. HOTSPOT Ã For selection.
Generation of Fieldcatelog :
It is generated using 2 ways.
1)Manually
2)Automatically by using FM
Steps for Example Program on field catalog
Declare the internal table and work area for the field catalog
DATA : i_fcat TYPE slis_t_fieldcat_alv.
*DATA : wa_fcat TYPE slis_fieldcat_alv.
DATA : wa_fcat like LINE OF i_fcat.
*DATA : wa_fcat TYPE slis_fieldcat_alv.
DATA : wa_fcat like LINE OF i_fcat.
Fill the fieldcatelog Itab with all fields and their corresponding properties.
wa_fcat-col_pos = 1. "v_pos.
wa_fcat-fieldname = 'KUNNR'.
*wa_fcat-tabname = 'I_KNA1'.
WA_FCAT-SELTEXT_L = 'CUST_NUM'.
*WA_FCAT-EDIT = 'X'.
WA_FCAT-EMPHASIZE = 'C610'.
WA_FCAT-REF_TABNAME = 'KNA1'.
wa_fcat-fieldname = 'KUNNR'.
*wa_fcat-tabname = 'I_KNA1'.
WA_FCAT-SELTEXT_L = 'CUST_NUM'.
*WA_FCAT-EDIT = 'X'.
WA_FCAT-EMPHASIZE = 'C610'.
WA_FCAT-REF_TABNAME = 'KNA1'.
WA_FCAT-REF_FIELDNAME = 'KUNNR'.
*WA_FCAT-KEY = 'X'.
APPEND WA_FCAT TO I_FCAT.
CLEAR WA_FCAT.
CLEAR WA_FCAT.
Call the function module and Export the field catalog in internal table as exporting parameters to IT_FCAT.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
I_CALLBACK_PROGRAM = 'SY-REPID'
IT_FIELDCAT = I_FCAT
TABLES
T_OUTTAB = I_KNA1.
EXPORTING
I_CALLBACK_PROGRAM = 'SY-REPID'
IT_FIELDCAT = I_FCAT
TABLES
T_OUTTAB = I_KNA1.
ALV with Layout
Layout
It is a structure or work area which is used to decorate or embellish the output of ALV Report
Layout contains the few properties to decorate the ALV output
The properties are,
1. ZEEBRA = ‘X’. Ã Displays ALV with alternative colors
2. COLWIDTH-OPTIMIZE = ‘X’. Ã Each column in ALV o/p displayed with maximum length, to display the entire data.
3. EDIT= ‘X’.Ã All the columns are displayed in editable mode.
4. NO_VLINE = ‘X’. Ã Vertical lines will not be displayed
5. NO_HLINE = ‘X’. Ã Horizontal lines will not be displayed
Steps:
Declare a work area for the Layout
DATA : wa_layout TYPE slis_layout_alv.
Fill the WA with various options.
wa_layout-zebra = 'X'.
wa_layout-colwidth_optimize = 'X'.
* wa_layout-edit = 'X'.
* wa_layout-no_vline = 'X'.
wa_layout-no_hline = 'X'.
wa_layout-colwidth_optimize = 'X'.
* wa_layout-edit = 'X'.
* wa_layout-no_vline = 'X'.
wa_layout-no_hline = 'X'.
Call the function module and send the WA as exporting parameter to IS_LAYOUT.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
I_CALLBACK_PROGRAM = SY-REPID
IS_LAYOUT = WA_LAYOUT
IT_FIELDCAT = I_FCAT
TABLES
T_OUTTAB = I_KNA1.
EXPORTING
I_CALLBACK_PROGRAM = SY-REPID
IS_LAYOUT = WA_LAYOUT
IT_FIELDCAT = I_FCAT
TABLES
T_OUTTAB = I_KNA1.
ALV Reports with Totals
The totals can be calculated in two ways
By clicking on ∑ ALV output field.
By programmatically setting the option
DO_SUM = ‘X’, for an currency/quantity field in FCAT
WA_FCAT-COL_POS = ’5’.
WA_FCAT-FIELDNAME = 'NETWR'.
WA_FCAT-SELTEXT_M = 'NETPRICE‘. WA_FCAT-DO_SUM = 'X'.
APPEND WA_FCAT TO I_FCAT.
WA_FCAT-FIELDNAME = 'NETWR'.
WA_FCAT-SELTEXT_M = 'NETPRICE‘. WA_FCAT-DO_SUM = 'X'.
APPEND WA_FCAT TO I_FCAT.
ALV Reports with and sub totals
To calculate sub totals, we need to find out on what basis (field name) the sub totals need to be calculated.
We need to sort the field in ascending order.
Then we need to set the property
SUBTOT = ‘X’ in FCAT.
WA_SORT-FIELDNAME = 'VBELN'.
WA_SORT-UP = 'X'.
WA_SORT-SUBTOT = 'X'.
APPEND WA_SORT TO I_SORT.
WA_SORT-UP = 'X'.
WA_SORT-SUBTOT = 'X'.
APPEND WA_SORT TO I_SORT.
Steps :
Declare the internal table and work area for the sorting
DATA : I_SORT TYPE SLIS_T_SORTINFO_ALV.
DATA : WA_SORT TYPE SLIS_SORTINFO_ALV.
DATA : WA_SORT TYPE SLIS_SORTINFO_ALV.
Specify the field and subtot = ‘X’ .
WA_SORT-FIELDNAME = 'VBELN'.
WA_SORT-UP = 'X'.
WA_SORT-SUBTOT = 'X'.
APPEND WA_SORT TO I_SORT.
WA_SORT-UP = 'X'.
WA_SORT-SUBTOT = 'X'.
APPEND WA_SORT TO I_SORT.
.
Call the function module and send the SORT internal table as exporting parameters to IT_SORT
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
I_CALLBACK_PROGRAM = SY-REPID
IT_FIELDCAT = I_FCAT
IT_SORT = I_SORT
TABLES
T_OUTTAB = I_VBAP.
EXPORTING
I_CALLBACK_PROGRAM = SY-REPID
IT_FIELDCAT = I_FCAT
IT_SORT = I_SORT
TABLES
T_OUTTAB = I_VBAP.
ALV with field catalog merge
We can create a field catalog either manually or by automatically
REUSE_ALV_FIELDCATELOG_MERGE is the function module which is used to create field catalog automatically
But this is obsolete because, the function module uses the old syntax for declaring internal tables
I.e. the internal table should be created as below and all the fields in the internal table must be declared using LIKE statement not the TYPE statement. DATA: BEGIN OF I_MARA OCCURS 0,
MATNR LIKE MARA-MATNR,
MTART LIKE MARA-MTART,
MEINS LIKE MARA-MEINS,
END OF I_MARA.
MATNR LIKE MARA-MATNR,
MTART LIKE MARA-MTART,
MEINS LIKE MARA-MEINS,
END OF I_MARA.
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE’

I_PROGRAM_NAME = SY-REPID
I_INTERNAL_TABNAME = 'I_MARA'
I_INCLNAME = SY-REPID

ELSEIF WA_FCAT-FIELDNAME = 'MTART'.
WA_FCAT-KEY = 'X‘.

MODIFY I_FCAT FROM WA_FCAT INDEX SY-TABIX.
ENDLOOP.
ENDLOOP.
