What are the routines available in abap
hi all,
I have found 2 routines so far widely used in abap.
They are conversion routines in data element and user defined routines in lswm.Can anyone let me know is there any other routines apart from the above 2 routines specified.
thanxs
hari
Some of the conversion routines
CHAR_HEX_CONVERSION
CHAR_INT_CONVERSION
CHAR_NUMC_CONVERSION
CHAR_PACK_CONVERSION
CONVERSION_EXIT_PARVW_INPUT
to know about conversion routines, check this link

What are the commands available to read a file from application server and
What are the commands available to read a file from application server and store the file into an internal table?
Hi,
To read a file from an Application Server to an Object there is a command in ABAP called <b>READ DATASET</b>. After that file is transported to that object you have to do a loop and put that data in an Internal Table.
This statement exports data from the file specified in dset into the data object dobj. For dobj, variables with elementary data types and flat structures can be specified. In Unicode programs, dobj must be character-type if the file was opened as a text file.
For dset, a character-type data object is expected - that is, an object that contains the platform-specific name of the file. The content is read from the file starting from the current file pointer. After the data transfer, the file pointer is positioned after the section that was read. Using the MAXIMUM LENGTH addition, the number of characters or bytes to be read from the file can be limited. Using ACTUAL LENGTH, the number of characters or bytes actually used can be determined.
In a Unicode program, the file must be opened with an arbitrary access type; otherwise, an exception that cannot be handled will be triggered.
If the file has not yet been opened in anon-Unicode program, it will be implicitly opened as a binary file for read access using the statement
OPEN DATASET dset FOR INPUT IN BINARY MODE.
. If a non-existing file is accessed, an exception that can be handled can be triggered.
Influence of Access Type
Files can be read independently of the access type. Whether data can be read or not depends solely on the position of the file pointer. If the latter is at the end of the file or after the file, no data can be read and sy-subrc will be set to 4.
Influence of the Storage Type
The import function will take place irrespective of the storage type in which the file was opened with the statement OPEN DATASET.
If the file was opened as a text file or as a legacy text file, the data is normally read from the current position of the file pointer to the next end-of-line marking, and the file pointer is positioned after the end-of-line marking. If the data object dobj is too short for the number of read characters, the superfluous characters and bytes are cut off. If it is longer, it will be filled with blanks to the right.
If the file was opened as a binary file or as a legacy-binary file, as much data is read that fits into the data object dobj. If the data object dobj is longer than the number of exported characters, it is filled with hexadecimal 0 on the right.
If the specified storage type makes conversion necessary, this is executed before the assignment to the data object dobj. Afterwards, the read data is placed, byte by byte, into the data object.
System Fields
sy-subrc Meaning
0 Data was read without reaching end of file.
4 Data was read and the end of the file was reached or there was an attempt to read after the end of the file.
Thanks,
Samantak.

What are the attributes available on Task Status Notification?
Hi,
I need to send the information below when a task is completed or rejected. So I would like to know if they are available. I think so because I've got them from Task Status Notification (OIM standard email definition). If not, what are the attributes available on Task Notification?
<Tasks.Task Name> is <Task Details.Status>.
<Task Details.Status>
<Resource.Resource Name>

Hi,
I have implemented some java code to workaround the problem below... But I don't believe this does'n work in OIM :-):-):-):-) Please, tell me if you are using task status notification in OIM and if your email defintion has the variables below.
Thanks,
Hi,
One of OIM email templates is Task Status Email Notification. I am trying to notify the user (Notification tab) using this template but it didn't work. Even when I set the Object Name and Process Name values for an email definition, it does not work.
How have you implemented task status notification in your workflows? I think if this template exists in OIM, by default, so it is posible to have the information below during notifications.
I think I'll have to call Oracle's Support.

I didn't get any answer until now.. Below it is what I've done.
a) Create an entity adapter that is assigned to the post-update of the Specific Task Info data object.
b) Select the task information searching by SCH_KEY, for example (I have to do more tests)
SELECT
sch.sch_key, sch.sch_status, sch.sch_note, mil.mil_key, rsc.rsc_data, rsc.rsc_desc
FROM
osi, sch, mil, rsc
WHERE
mil.mil_key = osi.mil_key and
osi.sch_key = sch.sch_key and
sch.sch_key = ? and
rsc.rsc_key = osi.rsc_key
c) Load the e-mail definition template and replaces the fields
d) Sends the e-mail
With that I solved another problem: I have to send an e-mail always the assignee adds a note to the task.

What are the frameworks available out there
I just want to know what are the frameworks available out there for Desktop application ?
I want to create a standalone application in Java and I heard that I can make it easier if I follow a framework.
After having a look at frameworks for Java, it just completely confuse me, as it is very different from frameworks for Flash (which I do most).
The java framework covers much more stuff than what Flash framework covers (which mainly regulate the way how the SWF communicate with the server and the design of the classes )
I still wonder what is the definition of framework in Java ? Do I really need one for a standalone application, or I just need to follow the MVC design for my classes ?
I just need to get it right before I actually work on my program.

What are the steps to optimise ABAP code
What are the steps to optimise ABAP code, that is how to increase the performance of a code?
Hi
Welcome to SDN forum
1) Dont use nested select statements
2) If possible use for all entries in addition
3) In the where addition make sure you give all the primary key
4) Use Index for the selection criteria.
5) You can also use inner joins
6) You can try to put the data from the first select statement into an Itab and then in order to select the data from the second table use for all entries in.
7) Use the runtime analysis SE30 and SQL Trace (ST05) to identify the performance and also to identify where the load is heavy, so that you can change the code accordingly
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/5d0db4c9-0e01-0010-b68f-9b1408d5f234
ABAP performance depends upon various factors and in devicded in three parts:
1. Database
2. ABAP
3. System
Run Any program using SE30 (performance analys) to improve performance refer to tips and trics section of SE30, Always remember that ABAP perfirmance is improved when there is least load on Database.
u can get an interactive grap in SE30 regarding this with a file.
also if u find runtime of parts of codes then use :
Switch on RTA Dynamically within ABAP Code
*To turn runtim analysis on within ABAP code insert the following code
SET RUN TIME ANALYZER ON.
*To turn runtim analysis off within ABAP code insert the following code
SET RUN TIME ANALYZER OFF.
Always check the driver internal tables is not empty, while using FOR ALL ENTRIES
Avoid for all entries in JOINS
Try to avoid joins and use FOR ALL ENTRIES.
Try to restrict the joins to 1 level only ie only for tables
Avoid using Select *.
Avoid having multiple Selects from the same table in the same object.
Try to minimize the number of variables to save memory.
The sequence of fields in 'where clause' must be as per primary/secondary index ( if any)
Avoid creation of index as far as possible
Avoid operators like <>, > , < & like % in where clause conditions
Avoid select/select single statements in loops.
Try to use 'binary search' in READ internal table. Ensure table is sorted before using BINARY SEARCH.

What are the tools available for gps NMEA data streams reception ?
Since no software for bluetooth connection for my Holux GPS device to my iPad2, I plan to write one myself. What are thr tools available and what is the simplest development platform just for this simple task? That is just to read the NMEA ASCII stream from the Bluetooth device.
It depends on what 'interprocess communication' your "app" program has available.
I regulary use DDE to control a PLL App which controls our PLL via the LPT Port. This is only a write process, but works very easily. The read is equaly easy. You need to know the various "keywords" like service, topic and instruction which the "app" will respond to.
Generaly I found ActieX to be more extensive, meaning its probably going to take longer and more steps to achive similar simple results.
The file does not seem to be the best way.
Hope that helps a bit. -

BATCH DATA COMMUNICATION
About Data Transfer In R/3 System
When a company decides to implement the SAP R/3 to manage business-critical data, it usually does not start from a no-data situation. Normally, a SAP R/3 project comes into replace or complement existing application.
In the process of replacing current applications and transferring application data, two situations might occur:
The first is when application data to be replaced is transferred at once, and only once.
The second situation is to transfer data periodically from external systems to SAP and vice versa.
There is a period of time when information has to be transferred from existing application, to SAP R/3, and often this process will be repetitive.
The SAP system offers two primary methods for transferring data into SAP systems. From non-SAP systems or legacy system. These two methods are collectively called batch input or batch data communication.
1. SESSION METHOD
2. CALL TRANSACTION
3. DIRECT INPUT
Advantages offered by BATCH INPUT method:
1. Can process large data volumes in batch.
2. Can be planned and submitted in the background.
3. No manual interaction is required when data is transferred.
4. Data integrity is maintained as whatever data is transferred to the table is through transaction. Hence batch input data is submitted to all the checks and validations.
To implement one of the supported data transfers, you must often write the program that exports the data from your non-SAP system. This program, known as a data transfer program must map the data from the external system into the data structure required by the SAP batch input program.
The batch input program must build all of the input to execute the SAP transaction.
Two main steps are required:
To build an internal table containing every screen and every field to be filled in during the execution of an SAP transaction.
To pass the table to SAP for processing.
Prerequisite for Data Transfer Program
Writing a Data Transfer Program involves following prerequisites:
Analyzing data from local file
Analyzing transaction
Analyzing transaction involves following steps:
The transaction code, if you do not already know it.
Which fields require input i.e., mandatory.
Which fields can you allow to default to standard values.
The names, types, and lengths of the fields that are used by a transaction.
Screen number and Name of module pool program behind a particular transaction.
To analyze a transaction::
Start the transaction by menu or by entering the transaction code in the command box.
(You can determine the transaction name by choosing System Status.)
Step through the transaction, entering the data will be required for processing your batch input data.
On each screen, note the program name and screen (dynpro) number.
(dynpro = dyn + pro. Dyn = screen, pro = number)
Display these by choosing System Status. The relevant fields are Program (dynpro) and Dynpro number. If pop-up windows occur during execution, you can get the program name and screen number by pressing F1 on any field or button on the screen.
The technical info pop-up shows not only the field information but also the program and screen.
For each field, check box, and radio button on each screen, press F1 (help) and then choose Technical Info.
Note the following information:
- The field name for batch input, which youll find in its own box.
- The length and data type of the field. You can display this information by double clicking on the Data Element field.
Find out the identification code for each function (button or menu) that you must execute to process the batch-input data (or to go to new screen).
Place the cursor on the button or menu entry while holding down the left mouse button. Then press F1.
In the pop-up window that follows, choose Technical info and note the code that is shown in the Function field.
You can also run any function that is assigned to a function key by way of the function key number. To display the list of available function keys, click on the right mouse button. Note the key number that is assigned to the functions you want to run.
Once you have program name, screen number, field name (screen field name), you can start writing.
DATA TRANSFER program.
Declaring internal table
First Integral Table similar to structure like local file.
Declaring internal table like BDCDATA
The data from internal table is not transferred directly to database table, it has to go through transaction. You need to pass data to particular screen and to particular screen-field. Data is passed to transaction in particular format, hence there is a need for batch input structure.
The batch input structure stores the data that is to be entered into SAP system and the actions that are necessary to process the data. The batch input structure is used by all of the batch input methods. You can use the same structure for all types of batch input, regardless of whether you are creating a session in the batch input queue or using CALL TRANSACTION.
This structure is BDCDATA, which can contain the batch input data for only a single run of a transaction. The typical processing loop in a program is as follows:
Create a BDCDATA structure
Write the structure out to a session or process it with CALL TRANSACTION USING; and then
Create a BDCDATA structure for the next transaction that is to be processed.
Within a BDCDATA structure, organize the data of screens in a transaction. Each screen that is processed in the course of a transaction must be identified with a BDCDATA record. This record uses the Program, Dynpro, and Dynbegin fields of the structure.
The screen identifier record is followed by a separate BDCDATA record for each value, to be entered into a field. These records use the FNAM and FVAL fields of the BDCDATA structure. Values to be entered in a field can be any of the following:
Data that is entered into screen fields.
Function codes that are entered into the command field. Such function codes execute functions in a transaction, such as Save or Enter.
The BDCDATA structure contains the following fields:
PROGRAM: Name of module pool program associated with the screen. Set this field only for the first record for the screen.
DYNPRO: Screen Number. Set this field only in the first record for the screen.
DYNBEGIN: Indicates the first record for the screen. Set this field to X, only for the first record for the screen. (Reset to (blank) for all other records.)
FNAM: Field Name. The FNAM field is not case-sensitive.
FVAL: Value for the field named in FNAM. The FVAL field is case-sensitive. Values assigned to this field are always padded on the right, if they are less than 132 characters. Values must be in character format.
Transferring data from local file to internal table
Data is uploaded to internal table by UPLOAD of WS_UPLOAD function.
Population of BDCDATA
For each record of internal table, you need to populate Internal table, which is similar to BDCDATA structure.
All these five initial steps are necessary for any type of BDC interface.
DATA TRANSFER program can call SESSION METHOD or CALL TRANSACTION. The initial steps for both the methods are same.
First step for both the methods is to upload the data to internal table. From Internal Table, the data is transferred to database table by two ways i.e., Session method and Call transaction.
SESSION METHOD
About Session method
In this method you transfer data from internal table to database table through sessions.
In this method, an ABAP/4 program reads the external data that is to be entered in the SAP System and stores the data in session. A session stores the actions that are required to enter your data using normal SAP transaction i.e., Data is transferred to session which in turn transfers data to database table.
Session is intermediate step between internal table and database table. Data along with its action is stored in session i.e., data for screen fields, to which screen it is passed, the program name behind it, and how the next screen is processed.
When the program has finished generating the session, you can run the session to execute the SAP transactions in it. You can either explicitly start and monitor a session or have the session run in the background processing system.
Unless session is processed, the data is not transferred to database table.
BDC_OPEN_GROUP
You create the session through program by BDC_OPEN_GROUP function.
Parameters to this function are:
User Name: User name
Group: Name of the session
Lock Date: The date on which you want to process the session.
Keep: This parameter is passed as X when you want to retain session after
processing it or to delete it after processing.
BDC_INSERT
This function creates the session & data is transferred to Session.
Parameters to this function are:
Tcode: Transaction Name
Dynprotab: BDC Data
BDC_CLOSE_GROUP
This function closes the BDC Group. No Parameters.
Some additional information for session processing
When the session is generated using the KEEP option within the BDC_OPEN_GROUP, the system always keeps the sessions in the queue, whether it has been processed successfully or not.
However, if the session is processed, you have to delete it manually. When session processing is completed successfully while KEEP option was not set, it will be removed automatically from the session queue. Log is not removed for that session.
If the batch-input session is terminated with errors, then it appears in the list of INCORRECT session and it can be processed again. To correct incorrect session, you can analyze the session. The Analysis function allows to determine which screen and value has produced the error. If you find small errors in data, you can correct them interactively, otherwise you need to modify batch input program, which has generated the session or many times even the data file.
CALL TRANSACTION
About CALL TRANSACTION
A technique similar to SESSION method, while batch input is a two-step procedure, Call Transaction does both steps online, one after the other. In this method, you call a transaction from your program by
Call transaction <tcode> using <BDCTAB>
Mode <A/N/E>
Update <S/A>
Messages into <MSGTAB>.
Parameter 1 is transaction code.
Parameter 2 is name of BDCTAB table.
Parameter 3 here you are specifying mode in which you execute transaction
A is all screen mode. All the screen of transaction are displayed.
N is no screen mode. No screen is displayed when you execute the transaction.
E is error screen. Only those screens are displayed wherein you have error record.
Parameter 4 here you are specifying update type by which database table is updated.
S is for Synchronous update in which if you change data of one table then all the related Tables gets updated. And sy-subrc is returned i.e., sy-subrc is returned for once and all.
A is for Asynchronous update. When you change data of one table, the sy-subrc is returned. And then updating of other affected tables takes place. So if system fails to update other tables, still sy-subrc returned is 0 (i.e., when first table gets updated).
Parameter 5 when you update database table, operation is either successful or unsuccessful or operation is successful with some warning. These messages are stored in internal table, which you specify along with MESSAGE statement. This internal table should be declared like BDCMSGCOLL, a structure available in ABAP/4. It contains the following fields:
1. Tcode: Transaction code
2. Dyname: Batch point module name
3. Dynumb: Batch input Dyn number
4. Msgtyp: Batch input message type (A/E/W/I/S)
5. Msgspra: Batch input Lang, id of message
6. Msgid: Message id
7. MsgvN: Message variables (N = 1 - 4)
For each entry, which is updated in database, table message is available in BDCMSGCOLL. As BDCMSGCOLL is structure, you need to declare a internal table which can contain multiple records (unlike structure).
Steps for CALL TRANSACTION method
1. Internal table for the data (structure similar to your local file)
2. BDCTAB like BDCDATA
3. UPLOAD or WS_UPLOAD function to upload the data from local file to itab. (Considering file is local file)
4. Loop at itab.
Populate BDCTAB table.
Call transaction <tcode> using <BDCTAB>
Mode <A/N/E>
Update <S/A>.
Refresh BDCTAB.
Endloop.
(To populate BDCTAB, You need to transfer each and every field)
The major differences between Session method and Call transaction are as follows:
SESSION METHOD CALL TRANSACTION
1. Data is not updated in database table unless Session is processed. Immediate updation in database table.
2. No sy-subrc is returned. Sy-subrc is returned.
3. Error log is created for error records. Errors need to be handled explicitly
4. Updation in database table is always synchronous Updation in database table can be synchronous Or Asynchronous.
Error Handling in CALL TRANSACTION
When Session Method updates the records in database table, error records are stored in the log file. In Call transaction there is no such log file available and error record is lost unless handled. Usually you need to give report of all the error records i.e., records which are not inserted or updated in the database table. This can be done by the following method:
Steps for the error handling in CALL TRANSACTION
1. Internal table for the data (structure similar to your local file)
2. BDCTAB like BDCDATA
3. Internal table BDCMSG like BDCMSGCOLL
4. Internal table similar to Ist internal table
(Third and fourth steps are for error handling)
5. UPLOAD or WS_UPLOAD function to upload the data from the local file to itab. (Considering file is local file)
6. Loop at itab.
Populate BDCTAB table.
Call transaction <tr.code> using <Bdctab>
Mode <A/N/E>
Update <S/A>
Messages <BDCMSG>.
Perform check.
Refresh BDCTAB.
Endloop.
7 Form check.
IF sy-subrc <> 0. (Call transaction returns the sy-subrc if updating is not successful).
Call function Format_message.
(This function is called to store the message given by system and to display it along with record)
Append itab2.
Display the record and message.
DIRECT INPUT
About Direct Input
In contrast to batch input, this technique does not create sessions, but stores the data directly. It does not simulate the online transaction. To enter the data into the corresponding database tables directly, the system calls a number of function modules that execute any necessary checks. In case of errors, the direct input technique provides a restart mechanism. However, to be able to activate the restart mechanism, direct input programs must be executed in the background only. Direct input checks the data thoroughly and then updates the database directly.
You can start a Direct Input program in two ways;
Start the program directly
This is the quickest way to see if the program works with your flat file. This option is possible with all direct input programs. If the program ends abnormally, you will not have any logs telling you what has or has not been posted. To minimize the chance of this happening, always use the check file option for the first run with your flat file. This allows you to detect format errors before transfer.
Starting the program via the DI administration transaction
This transaction restarts the processing, if the data transfer program aborts. Since DI document are immediately posted into the SAP D/B, the restart option prevents the duplicate document posting that occurs during a program restart (i.e., without adjusting your flat file).
Direct input is usually done for standard data like material master, FI accounting document, SD sales order and Classification for which SAP has provided standard programs.
First time you work with the Direct Input administration program, you will need to do some preparation before you can transfer data:
- Create variant
- Define job
- Start job
- Restart job
Common batch input errors
- The batch input BDCDATA structure tries to assign values to fields which do not exist in the current transaction screen.
- The screen in the BDCDATA structure does not match the right sequence, or an intermediate screen is missing.
- On exceptional occasions, the logic flow of batch input session does not exactly match that of manual online processing. Testing the sessions online can discover by this.
- The BDCDATA structure contains fields, which are longer than the actual definition.
- Authorization problems.
RECORDING A BATCH INPUT
A B recording allows you to record a R/3 transaction and generate a program that contains all screens and field information in the required BDC-DATA format.
You can either use SHDB transaction for recording or
SYSTEM ? SERVICES ? BATCH INPUT ? EDIT
And from here click recording.
Enter name for the recording.
(Dates are optional)
Click recording.
Enter transaction code.
Enter.
Click Save button.
You finally come to a screen where, you have all the information for each screen including BDC_OKCODE.
Click Get Transaction.
Return to BI.
Click overview.
Position the cursor on the just recorded entry and click generate program.
Enter program name.
Click enter
The program is generated for the particular transaction.
BACKGROUND PROCESSING
Need for Background processing
When a large volume of data is involved, usually all batch inputs are done in background.
The R/3 system includes functions that allow users to work non-interactively or offline. The background processing systems handle these functions.
Non-interactively means that instead of executing the ABAP/4 programs and waiting for an answer, user can submit those programs for execution at a more convenient planned time.
There are several reasons to submit programs for background execution.
The maximum time allowed for online execution should not exceed 300 seconds. User gets TIMEOUT error and an aborted transaction, if time for execution exceeds 300 seconds. To avoid these types of error, you can submit jobs for background processing.
You can use the system while your program is executing.
This does not mean that interactive or online work is not useful. Both type of processing have their own purposes. Online work is the most common one entering business data, displaying information, printing small reports, managing the system and so on. Background jobs are mainly used for the following tasks; to process large amount of data, to execute periodic jobs without human intervention, to run program at a more convenient, planned time other than during normal working hours i.e., Nights or weekends.
The transaction for background processing is SM36.
Or
Tools ? Administration ? Jobs ? Define jobs
Or
System ? services ? Jobs
Components of the background jobs
A job in Background processing is a series of steps that can be scheduled and step is a program for background processing.
Job name. Define the name of assigned to the job. It identifies the job. You can specify up to 32 characters for the name.
Job class. Indicates the type of background processing priority assigned to the job.
The job class determines the priority of a job. The background system admits three types of job classes: A B & C, which correspond to job priority.
Job steps. Parameters to be passed for this screen are as follows:
Program name.
Variant if it is report program
Start criteria for the job: Option available for this are as follows:
Immediate - allows you to start a job immediately.
Date/Time - allows you to start a job at a specific name.
After job - you can start a job after a particular job.
After event - allows you to start a job after a particular event.
At operation mode - allows you to start a job when the system switches to a particular operation mode.
Defining Background jobs
It is two step process: Firstly, you define the job and then release it.
When users define a job and save it, they are actually scheduling the report i.e., specifying the job components, the steps, the start time.
When users schedule program for background processing, they are instructing the system to execute an ABAP/4 report or an external program in the background. Scheduled jobs are not executed until they are released. When jobs are released, they are sent for execution to the background processing system at the specified start time. Both scheduling and releasing of jobs require authorizations.
HANDLING OF POP UP SCREEN IN BDC
Many times in transaction pop up screen appears and for this screen you dont pass any record but some indication to system telling it to proceed further. For example: The following screen
To handle such screen, system has provided a variable called BDC_CURSOR. You pass this variable to BDCDATA and process the screen.
Usually such screen appears in many transactions, in this case you are just passing information, that YES you want to save the information, that means YES should be clicked. So you are transferring this information to BDCDATA i.e., field name of YES which is usually SPOT_OPTION. Instead of BDC_OKCODE, you are passing BDC_CURSOR.
BDC_CURSOR is also used to place cursor on particular field.
AN EXAMPLE WITH SESSION METHOD
Following program demonstrates how data is passed from flat file to SAP transaction and further to database table by using SESSION method.
The transaction is TFBA (to change customer).
A simple transaction where you are entering customer number on first screen and on next screen data is displayed for the particular customer number. Field, which we are changing here, are name and city. When you click on save, the changed record gets saved.
Prerequisite to write this BDC interface as indicated earlier is:
1. To find screen number
2. To find screen field names, type of the field and length of the field.
3. To find BDC_OKCODE for each screen
4. Create flat file.
Flat file can be created in your hard disk as follows:
1 Vinod Hyderabad
2 Kavitha Secunderabad
3 Kishore Hyderabad
(Where 1st character field is Customer number, 2nd field is Customer name and 3rd field is City.)
To transfer this data to database table SCUSTOM following interface can be used.
REPORT DEMO1.
Following internal table is to upload flat file.
DATA: BEGIN OF ITAB OCCURS 0,
ID(10),
NAME(25),
CITY(25),
END OF ITAB.
*Following internal table BDCDATA is to pass date from internal table to session.

What are the basic objects in abap dictionary ?
Try to provide the details if anyone knows about it.
The DDIC is nothing but the ABAP Dictionary. The ABAP Dictionary centrally describes and manages all the data definitions used in the system.
Data types
Data types are the actual type definitions in the ABAP Dictionary. They allow you to define elementary types, reference types, and complex types that are visible globally in the system. The data types of database tables are a subset of all possible types, namely flat structures.
Data Elements
Data elements in the ABAP Dictionary describe individual fields. They are the smallest indivisible units of the complex types described below, and are used to specify the types of columns in the database. Data elements can be elementary types or reference types.
Structures
A structure is a sequence of any other data types from the ABAP Dictionary, that is, data elements, structures, table types, or database tables. When you create a structure in the ABAP Dictionary, each component must have a name and a data type. In an ABAP program, you can use the TYPE addition to refer directly to a structure.
If you define a local data type in a program by referring to a structure as follows:
TYPES <t> TYPE <structure>.
Table Types
Table types are construction blueprints for internal tables that are stored in the ABAP Dictionary.
When you create a table type in the ABAP Dictionary, you specify the line type, access type, and key. The line type can be any data type from the ABAP Dictionary, that is, a data element, a structure, a table type, or the type of a database table. You can also enter a predefined Dictionary type directly as the line type, in the same way that you can with a domain.
Type Groups
Before Release 4.5A, it was not possible to define standalone types in the ABAP Dictionary to which you could refer using a TYPE addition in an ABAP program. It was only possible to refer SAP AG BC - ABAP Programming
Data Types in the ABAP Dictionary to flat structures. Structures in programs corresponded to the structures of database tables or structures in the ABAP Dictionary. In ABAP programs, you could only refer to database tables and structures in the ABAP Dictionary using LIKE. It was, however, possible to refer to individual components of the Dictionary type. Complex local data types such as internal tables or deep structures had no equivalent in the ABAP Dictionary. The solution to this from Release 3.0 onwards was to use type groups. Type groups were based on the include technique, and allowed you to store any type definitions globally in the Dictionary by defining them using TYPES statements.
Views:
There are 4 types views are avilable in SAP.
Database View - To club more than one table
Projection View - To hide fields in one table
Maintanance View - To maintain database records in table
Help View - To provide help for a fields (Same functionality as Search help. This is outdated)
View are improves perfromance in the following aspects
1. If you want to use more than two table in 'JOIN' condition better to use Views . It will improves performance of a program
2. If you want to use mutiple FOR ALL ENTRIES clause, better to club all SELECT statement in a view.
Lock Objects:
Lock objects are use in SAP to avoid the inconsistancy at the time of data is being insert/change into database.
SAP Provide three type of Lock objects.
Read Lock(Shared Locked)
protects read access to an object. The read lock allows other transactions read access but not write access to
the locked area of the table
Write Lock(exclusive lock)
protects write access to an object. The write lock allows other transactions neither read nor write access to
the locked area of the table.
Enhanced write lock (exclusive lock without cumulating)
works like a write lock except that the enhanced write lock also protects from further accesses from the
same transaction.
You can create a lock on a object of SAP thorugh transaction SE11 and enter any meaningful name start with EZ Example EZTEST_LOCK.
Use: you can see in almost all transaction when you are open an object in Change mode SAP could not allow to any other user to open the same object in change mode.
Example: in HR when we are enter a personal number in master data maintainance screen SAP can't allow to any other user to use same personal number for changes.
Technicaly:
When you create a lock object System automatically creat two function module.
1. ENQUEUE_<Lockobject name>. to insert the object in a queue.
2. DEQUEUE_<Lockobject name>. To remove the object is being queued through above FM.
You have to use these function module in your program.
Search Helps:
These are two types.
Elementary n Collective.
1) Elementary search helps describe a search path. The elementary search help must define where the data of the hit list should be read from (selection method), how the exchange of values between the screen template and selection method is implemented (interface of the search help) and how the online input help should be defined (online behavior of the search help).
2) Collective search helps combine several elementary search helps. A collective search help thus can offer several alternative search paths.
3)An elementary search help defines the standard flow of an input help.
4) A collective search help combines several elementary search helps. The user can thus choose one of several alternative search paths with a collective search help.
5)A collective search help comprises several elementary search helps. It combines all the search paths that are meaningful for a field.
6)Both elementary search helps and other search helps can be included in a collective search help. If other collective search helps are contained in a collective search help, they are expanded to the level of the elementary search helps when the input help is called.
