Creating your own SAP Customized Main Menu

You can add additional menu transaction in the SAP main menu without affecting the original SAP default area menu S000.
For example, you have created a transaction code called ( z123 - ABC Own Report ) and you want to insert it under Logistics.  The specific user will be able to access ABC Own Report by clicking Logistics -> ABC Own Report.
Steps :-

• Goto Transaction SE43 - Area Menu
• Click the copy button.  Copy from S000 to ZXXX
• After copying, click Change (area menu ZXXX)
• Double click on Logistics and add in your transaction code in the AreaMenu.
• Remembers to Activate it.
• Next Goto Transaction SU01 - Maintain users
• Type in the user name and click the Defaults button
• Type in the area menu (ZXXX) in the Start Menu field.

• Click Save
• The user will be able to see the additional transaction on the next logon.

The CUA area menus are converted to tree navigation in Release 4.6A. The menu contents are automatically copied into a new data structure in Upgrade to Release 4.6A or higher. You can edit Area Menus with a new maintenance interface (Area Menu maintenance transaction: SE43 ). Reporting Tree Integration - Only transactions could previously be put in Area Menus. From Release 4.6A you can also put all the types of reports which are in reporting trees, in Area Menus. The system automatically assigns a transaction code to call the report from the menu. If you have already put the report in another Area Menu, no new transaction code is generated, the unique transaction code already assigned is used.
You can create Area Menus from complete reporting trees with the migration transaction RTTREE_MIGRATION . The report transaction codes are generated automatically.
Reporting trees can only be displayed. They cannot be maintained. To modify the contents of reporting trees, you must convert them with the migration transaction. You can then modify the contents with the Area Menu maintenance.

Please note that this example maybe slow at filling the 

excel table(perhaps four fields per second on a 900 MHz 

machine - almost 30 seconds for a short example). 

To get the data on properties and methods - there is a 

bit of smoke and mirrors going on here; they are EXCEL 

properties and methods, not sap ones - so you need 
to look at excel help to determine how a particular

function is structured. then build the block in sap, 

as shown in the example.
 
If you only want to transfer the data to Excel like 

when you transfer the data from ALV to Excel simply use the 

Function Modules: 

XXL_SIMPLE_API 

If you want more modifications when you transfer it to 

Excel use: 

XXL_FULL_API 

RFC call to get Server List

How to get the RFC call to get the list of SAP Servers (Different machines)?
Does such a thing exist (From SAPRFC.INI may be?) but the INI file is not a good option as I would need to check
the connection availability.
 
A list of application servers within an R/3 system can be obtained by calling function module 'TH_DISPLAY_SERVER_LIST' 
For example: 
REPORT ZSERVERLIST.
call function 'TH_DISPLAY_SERVER_LIST'.

How to get rid of dumps

Generally if any exception occurred it will go to dump immediately in a program, then we will process this through the tcode ST22(dump analysis). Here I am trying to convert this dump into an error message or some text statement.
For this you need to call this statement...

Transport standard text

use RSTXTRAN program

All the text elements are customizing requests.
Or else you can use scc1 between clients to copy text elements.

Insert a blank line at the end of the file using gui_upload

Try this..

To the GUI_DOWNLOAD Fm pass WRITE_LF_AFTER_LAST_LINE = ' '.

Random number creation

use one of the function modules

SYSTEM_GET_UNIQUE_ID
SDOK_UNIQUE_ID_GET
STREE_GET_UNIQUE_ID
QF05_RANDOM_INTEGER
SYSTEM_UUID_C_CREATE
NUMBER_GET_NEXT Creat a number Range object using transction SNRO.

Different select statements

For all entries

The for all entries creates a where clause, where all the entries in the driver table are combined with OR. If the number of
entries in the driver table is larger than rsdb/max_blocking_factor, several similar SQL statements are executed to limit the
length of the WHERE clause.
The plus

Large amount of data
Mixing processing and reading of data
Fast internal reprocessing of data
Fast
The Minus
Difficult to program/understand
Memory could be critical (use FREE or PACKAGE size)
Some steps that might make FOR ALL ENTRIES more efficient:
Removing duplicates from the the driver table
Sorting the driver table
If possible, convert the data in the driver table to ranges so a BETWEEN statement is used instead of and OR statement:
FOR ALL ENTRIES IN i_tab
WHERE mykey >= i_tab-low and
mykey <= i_tab-high.
Nested selects

The plus:
Small amount of data
Mixing processing and reading of data
Easy to code - and understand
The minus:
Large amount of data
when mixed processing isn’t needed
Performance killer no. 1

Select using JOINS

The plus
Very large amount of data
Similar to Nested selects - when the accesses are planned by the programmer
In some cases the fastest
Not so memory critical
The minus
Very difficult to program/understand
Mixing processing and reading of data not possible

Use the selection criteria

SELECT * FROM SBOOK.
CHECK: SBOOK-CARRID = 'LH' AND
SBOOK-CONNID = '0400'.
ENDSELECT.
SELECT * FROM SBOOK
WHERE CARRID = 'LH' AND
CONNID = '0400'.
ENDSELECT.

Use the aggregated functions

C4A = '000'.
SELECT * FROM T100
WHERE SPRSL = 'D' AND
ARBGB = '00'.
CHECK: T100-MSGNR > C4A.
C4A = T100-MSGNR.
ENDSELECT.

SELECT MAX( MSGNR ) FROM T100 INTO C4A
WHERE SPRSL = 'D' AND
ARBGB = '00'.

Select with view

SELECT * FROM DD01L
WHERE DOMNAME LIKE 'CHAR%'
AND AS4LOCAL = 'A'.
SELECT SINGLE * FROM DD01T
WHERE DOMNAME = DD01L-DOMNAME
AND AS4LOCAL = 'A'
AND AS4VERS = DD01L-AS4VERS
AND DDLANGUAGE = SY-LANGU.
ENDSELECT.

SELECT * FROM DD01V
WHERE DOMNAME LIKE 'CHAR%'
AND DDLANGUAGE = SY-LANGU.
ENDSELECT.

Select with index support

SELECT * FROM T100
WHERE ARBGB = '00'
AND MSGNR = '999'.
ENDSELECT.

SELECT * FROM T002.
SELECT * FROM T100
WHERE SPRSL = T002-SPRAS
AND ARBGB = '00'
AND MSGNR = '999'.
ENDSELECT.
ENDSELECT.


Select … Into table

REFRESH X006.
SELECT * FROM T006 INTO X006.
APPEND X006.
ENDSELECT

SELECT * FROM T006 INTO TABLE X006.


Select with selection list

SELECT * FROM DD01L
WHERE DOMNAME LIKE 'CHAR%'
AND AS4LOCAL = 'A'.
ENDSELECT

SELECT DOMNAME FROM DD01L
INTO DD01L-DOMNAME
WHERE DOMNAME LIKE 'CHAR%'
AND AS4LOCAL = 'A'.
ENDSELECT

Copying internal tables

REFRESH TAB_DEST.
LOOP AT TAB_SRC INTO TAB_DEST.
APPEND TAB_DEST.

LOOP AT TAB.
IF TAB-FLAG IS INITIAL.
TAB-FLAG = 'X'.
ENDIF.
MODIFY TAB.
ENDLOOP.

MODIFY TAB TRANSPORTING FLAG
WHERE FLAG IS INITIAL.

Deleting a sequence of lines

DO 101 TIMES.
DELETE TAB_DEST INDEX 450.
ENDDO.

DELETE TAB_DEST FROM 450 TO 550.


Linear search vs. binary

READ TABLE TAB WITH KEY K = 'X'.

READ TABLE TAB WITH KEY K = 'X' BINARY SEARCH.
Comparison of internal tables
DESCRIBE TABLE: TAB1 LINES L1,
TAB2 LINES L2.

IF L1 <> L2.
TAB_DIFFERENT = 'X'.
ELSE.
TAB_DIFFERENT = SPACE.
LOOP AT TAB1.
READ TABLE TAB2 INDEX SY-TABIX.
IF TAB1 <> TAB2.
TAB_DIFFERENT = 'X'. EXIT.
ENDIF.

ENDLOOP.

WA-DATE = SY-DATUM.
LOOP AT TAB.
MODIFY TAB FROM WA TRANSPORTING DATE.
ENDLOOP.

Appending two internal tables

LOOP AT TAB_SRC.

Optimizing the load of the database

Using table buffering
Using buffered tables improves the performance considerably. Note that in some cases a stament can not be used with a buffered table, so when using these staments the buffer will be bypassed. These staments are:
Select DISTINCT
ORDER BY / GROUP BY / HAVING clause
Any WHERE clasuse that contains a subquery or IS NULL expression
JOIN s
A SELECT... FOR UPDATE
If you wnat to explicitly bypass the bufer, use the BYPASS BUFFER addition to the SELECT clause.
Use the ABAP SORT Clause Instead of ORDER BY
The ORDER BY clause is executed on the database server while the ABAP SORT statement is executed on the application server. The datbase server will usually be the bottleneck, so sometimes it is better to move thje sort from the datsbase server to the application server.
If you are not sorting by the primary key ( E.g. using the ORDER BY PRIMARY key statement) but are sorting by another key, it could be better to use the ABAP SORT stament to sort the data in an internal table. Note however that for very large result sets it might not be a feasible solution and you would want to let the datbase server sort it.

Avoid ther SELECT DISTINCT Statement

As with the ORDER BY clause it could be better to avoid using SELECT DISTINCT, if some of the fields are not part of an index. Instead use ABAP SORT + DELETE ADJACENT DUPLICATES on an internal table, to delete duplciate rows.
