Change layout format in ALV

Layout format in ALV defined in structure IS_LAYOUT as importing structure of ALV

REUSE_ALV_LIST_DISPLAY.

CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'

EXPORTING....

s_layout = wa_layout

....EXCEPTIONS

program_error = 1

OTHERS = 2.

Commonly used field:

IS_LAYOUT-ZEBRA: X=striped (zebra) pattern

IS_LAYOUT-BOX_FIELDNAME: insert column checkbox for each row to select row.How to inset checkbox:

. insert new field with type C in internal table ALV data to record selection indicator (X:selected).Example:

DATA: BEGIN OF t_alv OCCURS 1,

ield1,ield2,

.

BOX,END Of T_alv.

2. set IS_LAYOUT-BOX_FIELDNAME = fieldname in internal table ALV data.

Example:

S_LAYOUT-BOX_FIELDNAME = 'BOX'.

. At run time, t_alv-box will filled with 'X' for selected data.

CheckBox can be initiated in these ways:: selected, can not be changed

0: not selected, can not be changed

X: selected, can be changedSPACE (blank):not selected, can be changed: disable check box

IS_LAYOUT-COL_FIELDNAME

Cells can be colored individually using a color code which is contained in a column of the internal output table for tecord containing the cell.

Assign the name of the field to this parameter.

The internal output table field must be of type SLIS_T_SPECIALCOL_ALV.Principle: the color code field is entered for the record containing the cells to be colored. The field contains an intern

able with the above structure, containing the field names of the cells to be colored and the color code. The cell

oordinates are determined by the record position containing the color code and the column information in the color

able.The record structure of the internal color table of type SLIS_T_SPECIALCOL_ALV is as follows:

Color table-FIELDNAME = field name of the cell to be colored

Color table-COLOR-COL = color number (1 - 9)

Color table-COLOR-INT = bold (0 = off, 1 = on)Color table-COLOR-INV = inverse (0 = off, 1 = on)

Color table-NOKEYCOL = ignore key coloring ('X' = yes, ' ' = no)

f the parameter color table-FIELDNAME is not filled, the coloring applies to all fields, so the entire record is color---------------------------------------------------------------------------------------------------------------

Tabstrip in selection screen

To define a tabstrip area with tab pages in selection screen, use the following statements in your selection screendefinition:

SELECTION-SCREEN: BEGIN OF TABBED BLOCK FOR LINES,

TAB () USER-COMMAND

DEFAULT [PROGRAM ] SCREEN ],TAB () USER-COMMAND

DEFAULT [PROGRAM ] SCREEN ],

.END OF BLOCK .

This defines a tabstrip control with size . The tab pages , ... are assigned to the tab area. defines the width of the tab

itle. You must assign a function code area to each tab title.

For each tab title, the system automatically creates a character field in the ABAP program with the same name. In

titialization, you can assign a text to the field. This then appears as the title of the corresponding tab page on theelection screen.

You must assign a subscreen to each tab title. This will be displayed in the tab area when the user chooses that title.

You can assign one of the following as a subscreen:

. A subscreen screen defined using the Screen Painter.

The dialog modules containing its flow logic must be defined in the current ABAP program.

2. A selection screen subscreen, defined in an ABAP program.User actions will trigger the AT SELECTION-SCREEN event at least twice firstly for the "included" selection scr

we can use it for validation), then for the selection screen on which it appears.

This is simple program with three tab title.

Tab1 demonstrating input validation.Don't forget to create subscreen 0300 for Tab3.

Field catalog in ALV

Field catalog containing descriptions of the list output fields. You can use fields of the catalog to determine the num

ormat and column properties of the list to be displayed.

The field catalog contains more than 60 fields, some of which are only used internally. The field catalog is defined ihe Data Dictionary through table type LVC_T_FCAT.

We can get field description by calling function module REUSE_ALV_FIELDCATALOG_MERGE. You can see t

ample in my post aboutSimple ALV Report.

n general case, we only use few field to describe output field.

To make it easier I use this form:

Dynamic Table Maintenance

t is a good sample of how to create dynamic table maintenance by utilized SAP function moduleSTC1_FULLSCREEN_TABLE_CONTROL".

copy this code fromITToolbox

You can use it to replace funtion of SM31 with additional benefit.

. Because it is written in as customer program we can add additional feature, for example change history.

2. There is no need to create screen maintenance for all table because screen will automatically generated.

But, remember, this is only a demonstration of how to use STC1_FULLSCREEN_TABLE_CONTROL. Use it

arefully and only for customer table (Z*).

Because there is difficulty in write "" in blogger, I replace "" with "}" in this sample cod

Copy this sample code, then replace all "{" with "".

Performance Tuning - Operation on Internal Table

n development server you may not aware of performance tuning on operation on internal table, but it could become

problem when you are working on internal table containing more 10 thousand rows.

These are tips to improve your program performance.

READ Table WITH CriteriaBy default, read command on internal table will read it sequentially. The binary search algorithm helps faster search

value in an internal table. But you must sort it before use binary search. Binary search repeatedly divides the searc

nterval in half. If the value to be searched is less than the item in the middle of the interval, the search is narrowed t

he lower half, otherwise the search is narrowed to the upper half.

SORT TABLE BYfield1.

READ TABLE table1WITH KEYfield1 = criteria1BINARY SEARCH.

Do try it for internal table containing more than 10 thousand rows, you will find it significantly improve performanc

uning.

You can apply binary search method to improve performance on nested loop.

Nested loop:

LOOP AT inttab1.

LOOP AT inttab2 WHERE intab2-field1 = intab1-field1.

ENDLOOP.

NDLOOP.

Replace above code with additional binary search.

ORT inttab2 BY field1.

LOOP AT inttab1.

READ TABLE inttab2WITH KEY field1 = inttab1-field1 BINARY SEARCH.

CHECK sy-subrc = 0.

LOOP AT inttab2 FROM sy-tabix.

IF inttab2-field1 NE inttab1-field1.

EXIT.

ENDIF.

ENDLOOP.

We can add new toolbar (maximal 5) in ABAP report to make program more interactive to user on selection screen.

2. Define text displayed in button in initialization event.

Help Value Request (F4)
