SAP AND ABAP TIPS AND FACTS

If you wish to display text in any of your reports that needs to be printed, then you can make use of text elements. It is a good practice not to hard code the text in the programs. If the text is maintained centrally, then it can be called in any report and redundancy can be avoided. Moreover if the text needs to be changed then it can be done at one place rather than changing every instance if it is hard coded.

Text element maintenance can be done in the ABAP Workbench. It is used to maintain program text in different languages. The text that program uses can be maintained centrally for a program.

Logon to SAP
SAP database has numerous tables. For viewing the content of a particular table SAP has provided a tool which can be accessed using some transactions. An ABAP programmer can display the data of a particular table using a report but this cab be easily achieved using the tools provided by SAP. As an ABAP programmer if you wish to quickly view the contents of a particular table the best way is to use this tool and the corresponding transactions.

Enter Transaction Code SE11.

Note that transaction SE11 can be used to Display/Change/Create database tables. Other transactions for ABAP dictionary are as follows

SE12 Display
Database Tables
View
Data Types
Domain
Search Help
Lock Objects

SE11 Display/Change/Create

SE16 and SE16N Data Browser




Enter the Table name in this case VBAK



Click on Display.

Click on COntents as shown below or use shortcut
CTRL+SHIFT+F10



Enter the desired data. In this case the sales order number.



The data is displayed as shown below.

Retrieve the data from the SAP database using the select statement and the where clause.

For database programming writing queries to retrieve the data from SAP database is essential. This is achieved with the help of the SELECT statement. There are various ways of writing the SELECT statement and we have given you a few examples below. The most essential part of the SELECT statement apart from the syntax is that the data should be selected as per the desired result. There should not be any redundancy also the efficiency of the query should be taken care of, that means the report should run quickly in the most efficient way without overloading the system.

Some examples of SAP - ABAP SELECT Statement.

SELECT *
INTO wa
FROM (name) CLIENT SPECIFIED
WHERE mandt = '000'.
WRITE: / wa-carrid, wa-carrname.
ENDSELECT.


SELECT *
INTO wa
FROM scarr UP TO 4 ROWS.
WRITE: / wa-carrid, wa-carrname.
ENDSELECT.

For more examples pleas refer to SAP help click on the links given below.

SELECT Clause

Variants:

1. SELECT [SINGLE [FOR UPDATE] | DISTINCT] *
2. SELECT [SINGLE [FOR UPDATE] | DISTINCT] s1 ... sn
3. SELECT [SINGLE [FOR UPDATE] | DISTINCT] (itab)

Please check the following discussion on Selecting a single row.

Program to display sales order header data
If your job is to write ABAP programs/ reports you need to familiarize yourself with various functionalities of SAP. The SAP Sales and Distribution module (SD) allows you to create a Sales order. As an ABAPer you need to know at least the basics of Sales order creation. The transaction for creating a sales order is VA01, to Edit Sales order is VA02 and just to display a sales order is VA03. In case you are unable to create a sales order you can play around with an existing one in the development server. First open the sales order in the display mode and understand the fields that need to be extracted. Make a note of the tables.
In this program we will display the sales order header data.

Following fields will be displayed
  • Sales Order number
  • Sold to party number
  • Ship to party
  • Buyer
  • Net Value
  • Payment Terms

Focus

1) Retrieve the data from the SAP database using the SELECT statement and the WHERE clause
2) Selecting SINGLE rows
3) Using SELECT-OPTIONS
4) Displaying data from tables using SE11
5) Using TEXT ELEMENTS
6) Data Declaration
7) Table Declaration
8) Using the WRITE statement
9) Using the debugger
10) Using double click to display the table

Tables used

VBAK Sales Document Header Data
VBPA Sales Document Partner
VBKD Sales Document Business Data

Creating the first program in ABAP is easy. First you need to create a user account using transaction SU01. You can also ask the SAP basis person to create a user account for you with the appropriate authorizations. Also a developer key needs to be generated this can be taken care by the basis person. The first program should be created with the following things in mind. It should be simple, and should run as quickly as possible. It should familiarize you with all the steps involved in creating any ABAP report as it is called.

Steps to create a simple program in ABAP.
1) Login to SAP.
2) Enter the transaction code SE38 as shown in the figure.
3) Hit enter.
You will then be taken to the ABAP Editor initial screen.






Enter the name starting with Y or Z as shown below. Let the source code radio button be selected and then press create.


See the attributes dialog box below.




Click on Save



Enter $tmp in development class and click on save button

SAP ABAP

ABAP (Advanced Business Application Programming) is a programming language for developing applications for the SAP R/3 system, a widely-installed business application subsystem. The latest version, ABAP Objects, is object-oriented programming. SAP will run applications written using ABAP/4, the earlier ABAP version, as well as applications using ABAP Objects. ABAP is used extensively to build, customize and tune SAP as per the users requirements. ABAP is uswd for developing custom reports, Sap Scripts, Adobe Forms, Smart Forms, Interfaces, and many other applications that are specific to a particular business.

 ABAP TIPS


Since your web browser does not support JavaScript, here is a non-JavaScript version of the image slideshow:

 ABAP TIPS
Always specify your conditions in the Where-clause instead of checking them yourself with check statements. The database system can then use an index (if possible) and the network load is considerably less.


 ABAP TIPS
For all frequently used Select statements, try to use an index. You always use an index if you specify (a generic part of) the index fields concatenated with logical Ands in the Select statement's Where clause. Note that complex Where clauses are poison for the statement optimizer in any database system.


 ABAP TIPS
If there exists at least one row of a database table or view with a certain condition, use the Select Single statement instead of a Select-Endselect-loop. Select Single requires one communication with the database system, whereas Select-Endselect needs two.


 ABAP TIPS
It is always faster to use the Into Table version of a Select statement than to use Append statements.


 ABAP TIPS
To read data from several logically connected tables use a join instead of nested Select statements. Network load is considerably less.


 ABAP TIPS
If you want to find the maximum, minimum, sum and average value or the count of a database column, use a select list with aggregate functions instead of computing the aggregates yourself. Network load is considerably less.


 ABAP TIPS
If you process your data only once, use a Select-Endselect-loop instead of collecting data in an internal table with Select Into Table. Internal table handling takes up much more space.


 ABAP TIPS
Use a select list or a view instead of Select * , if you are only interested in specific columns of the table. Network load is considerably less.


 ABAP TIPS
For all frequently used, read-only tables, try to use SAP buffering. Network load is considerably less.


 ABAP TIPS
Whenever possible, use array operations instead of single-row operations to modify your database tables. Frequent communication between the application program and database system produces considerable overhead.


 ABAP TIPS
Whenever possible, use column updates instead of single-row updates to update your database tables. Network load is considerably less.


 ABAP TIPS
Instead of using nested Select loops or FOR ALL ENTRIES it is often possible to use subqueries. Network load is considerably less.


 ABAP TIPS
Use the special operators CO, CA, CS, instead of programming the operations yourself. If ABAP/4 statements are executed per character on long strings, CPU consumption can rise substantially.


 ABAP TIPS
Some function modules for string manipulation have become obsolete and should be replaced by ABAP/4 statements or functions: STRING_CONCATENATE... -> CONCATENATE, STRING_SPLIT... -> SPLIT, STRING_LENGTH -> strlen(), STRING_CENTER -> WRITE...TO...CENTERED, STRING_MOVE_RIGHT -> WRITE...TO...RIGHT-JUSTIFIED


 ABAP TIPS
Use the CONCATENATE statement instead of programming a string concatenation of your own.


 ABAP TIPS
If you want to delete the leading spaces in a string, use the ABAP/4 statement SHIFT...LEFT DELETING LEADING... .Other constructions (with CN and SHIFT...BY SY-FDPOS PLACES, with CONDENSE if possible, with CN and ASSIGN CLA+SY-FDPOS(LEN) ...) are not as fast. In any case, avoid using SHIFT inside a WHILE-loop!


 ABAP TIPS
Use the SPLIT statement instead of programming a string split yourself.


 ABAP TIPS
Use the strlen( ) function to restrict the DO loop to the relevant part of the field, e.g. when determinating a check-sum.


 ABAP TIPS
Use "CLEAR f WITH val" whenever you want to initialize a field with a value different from the field's type-specific initial value.


 ABAP TIPS
Try to keep the table ordered and use binary search or used a table of type SORTED TABLE. If TAB has n entries, linear search runs in O( n ) time, whereas binary search takes only O( log2( n ) ).


 ABAP TIPS
A dynamic key access is slower than a static one, since the key specification must be evaluated at runtime. However, for large tables the costs are dominated by number of comparison needed to locate the entry.


 ABAP TIPS
If you need to access an internal table with different keys repeatedly, keep your own secondary indices.With a secondary index, you can replace a linear search with a binary search plus an index access.


 ABAP TIPS
LOOP ... WHERE is faster than LOOP/CHECK because LOOP ... WHERE evaluates the specified condition internally. As with any logical expressions, the performance is better if the operands of a comparison share a common type. The performance can be further enhanced if LOOP ... WHERE is combined with FROM i1 and/or TO i2, if possible.


Always use Pretty Printer and Extended Program Check before releasing the code. Do not leave unused code in the program. Comment the code thoroughly. Align the comments and the Code. Follow the SAP Standards and SAP Best Practices guidelines. It’s a good practice to take a dump of the code on your local drive.
