Submitted By: Shilpa Gunjan (L&T Infotech) - Internal table is a temporary table created in RAM of Application Server while runtime which can be used to do operation on the data while processing. - The contents of a database table can be copied to an internal table at runtime, so that the internal table is a snapshot of a database table and can then be used as a working copy of the data within the program. In short, internal tables can be used as containers for volatile data in a program. - The database tables are been used across so many sap standard programs. We cannot directly play around with them. In order to avoid that as per the requirement of the program we go for the concept of internal tables during the program execution and use the internal tables and take the required data from the database table and then we can always play around with the data in the internal table. It is just like when you go the any supermarket, you take a basket (internal table) a...

26. What Is CTU_PARAMS In BDC? What Are The Different Components Available In This Structure? CTU_PARAMS is a structure which has components used to control processing of CALL_TRANSACTION. This structure is used to provide display mode, update mode, default size and more control components to the Call Transaction statement. The different components available in CTU_PARAMS are: DISMODE - Processing Mode A - All Screens N - No Screens E - Only Error Screens UPMODE - Update Mode S - Synchronous A - Asynchronous L - Local CATTMODE - CATT Means Computer Aided Test Tool Blank - No CATT Mode, N - CATT Without Single Screen Control A - CATT With Single Screen Control DEFSIZE - Default Size For Screen resolution. 'X' - Yes, ' ' - No. RACOMMIT - Do not end transaction at COMMIT WORK. 'X' - Yes, ' ' - No. NOBINPT - No batch input session active (that is, SY-BINPT = SPACE). SY-BINPT is always space during a CATT procedure. 'X' - ...

21. How To Capture Messages While Processing Call Transaction In BDC? System messages issued during the transaction can be stored in the as shown below. This internal table must be declared as TYPE TABLE OF BDCMSGCOLL. DATA: gt_bdcdata TYPE TABLE OF bdcdata WITH HEADER LINE, gt_msgtab TYPE TABLE OF bdcmsgcoll WITH HEADER LINE. CALL TRANSACTION 'xxxx' USING gt_bdcdata MODE 'N'' UPDATE 'S' MESSAGES INTO gt_msgtab. Internal table gt_msgtab contains only message no and message Id and not the actual message. In order to extract the exact message FORMAT_MESSAGE function module can be used. FORMAT_MESSAGE function module gives the actual message based on the message id, message no, and message variables. LOOP AT gt_messtab.    CALL FUNCTION 'FORMAT_MESSAGE'    EXPORTING       id = gt_bdcdata -msgid       lang = gt_bdcdata -msgspra       no = gt_bdcdata -msgnr       v1 = gt_bdcdat...

16. What Are The Difference Between Call Session Method & Call Transaction Method? Differences between Call Session Method & Call Transaction Method are: In CALL SESSION method, the SAP database is updated during the processing of the batch input session, not the execution of the BDC program. In CALL TRANSACTION method, the SAP database is updated during the execution of the BDC program. In CALL SESSION method , errors are handled automatically by the system during the processing of the batch input session. Errors are recorded in a log and with the batch input session, error is kept. In CALL TRANSACTION method, errors are not handled automatically by the system. Errors must be handled explicitly in the BDC program. In CALL SESSION method - Asynchronous Processing and Synchronous Database update. During processing, no transaction is started until the previous transaction has been written to the database. In CALL TRANSACTION method - Synchronous Processing and dat...

11. What Is The Importance Of KEEP Parameter In BDC_OPEN_GROUP Function Module? KEEP flag or parameter to indicate whether the batch input session should be kept (‘X’) or deleted (‘ ’) after the successful processing. The default value for this parameter is (‘ ‘)to delete the batch input session. 12. What Is The Importance Of POST_LOCAL Parameter In BDC_INSERT Function Module? POST_LOCAL parameter is used to set the update mode for the session. If this parameter is set to ‘X’ the update will run in asynchronous mode instead of the default synchronous one. 13. What Is The Biggest Disadvantage Of Using Batch Input Session Method? When dealing with batch input sessions, there is a timing issue involving the creation of a batch input session and the processing of a batch input session. The creation and processing of batch input sessions are distinct or two different actions; therefore, they occur at different times. Between the time a batch input session is created and the ...

6. What Are The Two Methods To Process Batch Input Sessions? There are two methods to process batch input session: Manually process batch input sessions in the Session Overview i.e. SM35 transaction code. Execute program RSBDCSUB. 7. For What Purpose RSBDCSUB Program Is Used? Using the Session Overview is one method to processing batch input sessions. Another method is to execute the RSBDCSUB program is used for processing batch input sessions. It schedules a session to be processed in the background. When this program is executed, a parameter screen prompts the user for the session name. Also one can schedule this program to be executed in background where a variant would be required for the parameter screen. Also by using SUBMIT statement, RSBDCSUB program can be executed from any ABAP program. 8. Which Transaction Is Used To Process Batch Input Session? What Are The Different Modes Of Processing Batch Input Sessions? Transaction code SM35 is used to process Batch ...

1. What Is BDC Programming? BDC stands for Batch Data Communication. Batch Data Communication (BDC) is the oldest batch interfacing technique that is available in SAP. BDC works on the principle of simulating user input for transactional screen, via an ABAP program. BDC is used to transfer data. Generally it is used to transfer data from one SAP system to another SAP system or from a non-SAP system to SAP system. To transfer the data BDC uses transactional codes available in the system. BDC is generally used to transfer large amounts of data into SAP system available in electronic form. 2. What Are The Advantages Of Using BDC As An Interface Technique? There are three advantages of using BDC as an interface technique: BDC works by carrying out normal SAP transactions just as a user would use it but it execute the transaction automatically. All the screen validations and business logic validation will be done while using Batch Data Input. BDC is suitable for entering large...

6. What Are The Various Opening Modes In OPEN DATASET Statement/Syntax? The various opening modes in OPEN DATASET Statement are: Use the ‘FOR’ options to specify the access mode. FOR INPUT (Default) – Opens an existing file for reading. FOR OUTPUT – Opens a file for writing. If the file does not exist, it is created.  If the file already exists, its contents are deleted. FOR APPENDING – Opens a file for writing. If the file does not exist, it is created.  If the file already exists, the system goes to the end of the file to add to it. Use the ‘IN’ options to specify the structure of the file. IN BINARY MODE (Default) – Indicates that the file is not structured in lines (i.e., it is set up byte-by-byte). IN TEXT MODE – Indicates that the file is structured in lines. AT POSITION - To open a file at specific position. 7.   What Is The Difference Between Opening A Sequential File In Text Mode & Binary Mode In Application Server? To determ...

1.   What Are Local Files? Local files are nothing but files available on your local system or your computer or we can also say files present on presentation sever are called local files. (For Example: File on your system desktop like C:\Desktop\testfile.txt 2.   What Are Sequential Files? A Sequential file is a collection of information stored and accessed sequentially in a database, often created to store information in a non-structured way. Comma Separated Value (CSV) sheets, for example, present information with each field separated from the next by a comma. Sequential file in application server are also sometimes referred as Datasets. Sequential files are used to transfer data between either two SAP systems or between SAP system and Non-SAP system. 3.   What Are The Steps To Process A File In Application Server? Processing a file refers to either creating a file or reading a file. Before a sequential file can be processed, it must be opened using OPEN...
