ALV reports are used to display data in grid or list format with predefined formatting options. The document discusses different techniques for developing ALV reports including using structures, field catalogs, layouts, totals, subtotals, and events. Function modules streamline the creation of field catalogs and allow for customization through events.

1. *ALV Reports*
BY ----Arjun

2. Review
ALV Reports are mainly used to display the data in the form of either
Grid or List Format with good Look and Feel.
The main advantages of ALV Reports are:
1. Good Look and Feel
2.Predefined options given by SAP like
Asc, Desc,
Filtering,
Downloading,
Changing Layout,
sending Mail…..etc

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

8. FieldCatelog: It is an int.Table which contains the list o the fields
along with field properties to be displayed in ALV Report
The properties/options are:
 1. COL_POS = 1.
 2. FIELD NAME Specifies the name of the field
 3. TABLE NAME Specifies the name of the internal table
 4. SELTEXT_S  Specifies short
 SELTEXT_L  Specifies Long
 SELTEXT_M  Specifies medium

9.  5. DO_SUM = ‘X’  For grand totals
 6. SUBTOT = ‘X’  Sub totals to be calculated
 7. EDIT = ‘X’  Field can be editable
 8. EMPHASIZE = ‘CXYZ’  Specifies the Color to the fields
 C – Indicates color
 X – Color Numbers
 Y – Backgroundcolor – 1 On BG color
 0 off BG color

12. 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.
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'.

APPEND WA_FCAT TO I_FCAT.

Call the function module and Export the field catalog in internal table

14.  ALV with field catalog merge
ã SAP AG 2001, Smart Forms - the Form Printing Solution,
Claudia Binder / Jens Stumpe 14

15. 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.
Example1 on FCAT using Internal table
DATA: BEGIN OF I_MARA OCCURS 0,
MATNR LIKE MARA-MATNR,
MTART LIKE MARA-MTART,
MEINS LIKE MARA-MEINS,
END OF I_MARA.

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’.  Displays ALV with alternative colors
 2. COLWIDTH-OPTIMIZE = ‘X’.  Each column in ALV o/p
displayed with maximum length, to display the entire data.
 3. EDIT= ‘X’. All the columns are displayed in editable mode.

21.  4. NO_VLINE = ‘X’.  Vertical lines will not be displayed
 5. NO_HLINE = ‘X’.  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'.

24. ALV Reports with Totals
The totals can be calculated in two ways
By clicking on Σ 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.

25.  ALV WITH SUBTOTALS
ã SAP AG 2001, Smart Forms - the Form Printing Solution,
Claudia Binder / Jens Stumpe 25

26. 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-spos = ‘1’.
WA_SORT-FIELDNAME = 'VBELN'.
WA_SORT-UP = 'X'.
WA_SORT-SUBTOT = 'X'.
APPEND WA_SORT TO I_SORT.
ã SAP AG 2001, Smart Forms - the Form Printing Solution,
Claudia Binder / Jens Stumpe 26

27. 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.
Specify the field and subtot = ‘X’ .
WA_SORT-FIELDNAME = 'VBELN'.
WA_SORT-UP = 'X'.
WA_SORT-SUBTOT = 'X'.
APPEND WA_SORT TO I_SORT.
