Title: none,
Type: 1 (Reporting),
Application: S (Basis).
You can specify the name of the program explicitly within single quotation marks or you can write the name of a character field, which contains the program name. The name of the program must not necessarily be the same as given in the coding, but it is recommended to do so. is the internal table containing the source code. For the above example you could write:
INSERT REPORT 'ZDYN1' FROM CODE.

Step loops fall into two classes: Static and Dynamic. Static step loops have a fixed size that cannot be changed at runtime. Dynamic step loops are variable in size. If the user re-sizes the window the system automatically increases or decreases the number of step loop blocks displayed. In any given screen you can define any number of static step loops but only a single dynamic one.
54. What are the two ways of producing a list within a transaction?
By submitting a separate report.
By using leave to list-processing.
55. What is the use of the statement Leave to List-processing?
Leave to List-processing statement is used to produce a list from a module pool. Leave to list processing statement allows to switch from dialog-mode to list-mode within a dialog program.
56. When will the current screen processing terminates?
A current screen processing terminates when control reaches either a Leave-screen or the end of PAI.
57. How is the command Suppress-Dialog useful?
Suppressing entire screens is possible using this command. This command allows us to perform screen processing "in the background". The system carries out all PBO and PAI logic, but does not display the screen to the user. Suppressing screens is useful when we are branching to list-mode from a transaction dialog step.
58. What happens if we use Leave to list-processing without using Suppress-Dialog?
If we don't use Suppress-Dialog to next screen will be displayed but as empty, when the user presses ENTER, the standard list output is displayed.
59. How the transaction that are programmed by the user can be protected?
By implementing an authority check.
60. What are the modes in which any update tasks work?
Synchronous and Asynchronous.
61. What is the difference between Synchronous and Asynchronous updates?
A program asks the system to perform a certain task, and then either waits or doesn't wait for the task to finish. In synchronous processing, the program waits: control returns to the program only when the task has been completed. In asynchronous processing, the program does not wait: the system returns control after merely logging the request for execution.
62. SAP system configuration incluedes Dialog tasks and Update tasks.
63. Dialog-task updates are Synchronous updates.
64. Update –task updates are Asynchronous updates.
65. What is the difference between Commit-work and Rollback-Work tasks?
Commit-Work statement "performs" many functions relevant to synchronized execution of tasks. Rollback-work statement "cancels: all reuests relevant to synchronized execution of tasks.
66. What are the different database integrities?
• Semantic Integrity.
• Relational Integrity.
• Primary Key Integrity.
• Value Set Integrity.
• Foreign Key integrity and
• Operational integrity.

68. What is SAP locking?
It is a mechanism for defining and applying logical locks to database objects.
69. What does a lock object involve?
The tables.
The lock argument.
70. What are the different kinds of lock modes?
Shared lock
Exclusive lock.
Extended exclusive list.
71. How can a lock object be called in the transaction?
By calling Enqueue and Dequeue in the transaction.
72. What are the events by which we can program "help texts" and display "possible value lists"?
-PROCESS ON HELP-REQUEST (POH).
-PROCESS ON VALUE-REQUEST (POV).
73. What is a matchcode?
A matchcode is an aid to finding records stored in the system whenever an object key is required in an input field but the user only knows other (non-key) information about the object.
74. In what ways we can get the context sensitive F1 help on a field?
- Data element documentation.
- Data element additional text in screen painter.
- Using the process on help request event.
75. What is roll area?
A roll area contains the program's runtime context. In addition to the runtime stack and other structures, all local variables and any data known to the program are stored here.
76. How does the system handle roll areas for external program components?
- Transactions run in their own roll areas.
- Reports run in their own roll areas.
- Dialog modules run in their own roll areas
- Function modules run in the roll area of their callers.
77. Does the external program run in the same SAP LUW as the caller, or in a separate one?
- Transactions run with a separate SAP LUW
- Reports run with a separate SAP LUW.
- Dialog modules run in the same SAP LUW as the caller
- Function modules run in the same SAP LUW as the caller.
The only exceptions to the above rules are function modules called with IN UPDATE TASK (V2 function only) or IN BACKGROUND TASK (ALE applications). These always run in their own (separate) update transactions.
78. What are function modules?
Function modules are general-purpose library routines that are available system-wide.
79. What are the types of parameters in the function modules?
In general, function module can have four types of parameters:
- EXPORTING: for passing data to the called function.
- IMPORTING: for receiving data returned from the function module.
- TABLES: for passing internal tables only, by reference (that is, by address).
- CHANGING: for passing parameters to and from the function.
80. What is the difference between Leave Transaction and Call Transaction?
In contrast to LEAVE TO TRANSACTION, the CALL TRANSACTION statement causes the system to start a new SAP LUW. This second SAP LUW runs parallel to the SAP LUW for the calling transaction.
81. How can we pass selection and parameter data to a report?
There are three options for passing selection and parameter data to the report.
- Using SUBMIT…WITH
- Using a report variant.
- Using a range table.
82. How to send a report to the printer instead of displaying it on the screen?
We can send a report to the printer instead of diplaying it on the screen. To do this, use the keywords TO SAP-SPOOL:
SUBMIT RSFLFIND…TO SAP-SPOOL DESTINATION 'LT50'.
83. How can we send data to external programs?
Using SPA/GPA parameters(SAP memory).
Using EXPORT/IMPORT data (ABAP/4 memory)
84. What are SPA/GPA parameters (SAP memory)
SPA/GPA parameters are field values saved globally in memory. There are two ways to use SPA/GPA parmeters:
By setting field attributes in the Screen Painter.
By using the SET PARAMETER or GET PARAMETER statements.
BDC
1. What is full form of BDC Session?
Batch Data Communication Session.
2. What are the steps in a BDC session?
The first step in a BDC session is to identify the screens of the transaction that the program will process. Next step is to write a program to build the BDC table that will be used to submit the data to SAP. The final step is to submit the BDC table to the system in the batch mode or as a single transaction by the CALL TRANSACTION command.
3. How do you find the information on the current screen?
The information on the current screen can be found by SYSTEM STATUS command from any menu.
4. How do you save data in BDC tables?
The data in BDC tables is saved by using the field name 'BDC_OKCODE' and field value of '/11'.
5. What is the last entry in all BDC tables?
In all BDC tables the last entry is to save the data by using the field name BDC_OKCODE and a field value of '/11'.
6. What is a multiple line field?
A multiple line field is a special kind of field which allows the user to enter multiple lines of data into it.
7. How do you populate data into a multiple line field?
To populate data into a multiple line field, an index is added to the field name to indicate which line is to be populated by the BDC session (Line index).
8. Write the BDC table structure.

59. How the transaction that are programmed by the user can be protected?
By implementing an authority check.
60. What are the modes in which any update tasks work?
Synchronous and Asynchronous.
61. What is the difference between Synchronous and Asynchronous updates?
A program asks the system to perform a certain task, and then either waits or doesn't wait for the task to finish. In synchronous processing, the program waits: control returns to the program only when the task has been completed. In asynchronous processing, the program does not wait: the system returns control after merely logging the request for execution.
62. SAP system configuration incluedes Dialog tasks and Update tasks.
63. Dialog-task updates are Synchronous updates.
64. Update –task updates are Asynchronous updates.
65. What is the difference between Commit-work and Rollback-Work tasks?
Commit-Work statement "performs" many functions relevant to synchronized execution of tasks. Rollback-work statement "cancels: all reuests relevant to synchronized execution of tasks.
66. What are the different database integrities?
• Semantic Integrity.
• Relational Integrity.
• Primary Key Integrity.
• Value Set Integrity.
• Foreign Key integrity and
• Operational integrity.
67. All SAP Databases are Relational Databases.
68. What is SAP locking?
It is a mechanism for defining and applying logical locks to database objects.
69. What does a lock object involve?
The tables.
The lock argument.
70. What are the different kinds of lock modes?
Shared lock
Exclusive lock.
Extended exclusive list.
71. How can a lock object be called in the transaction?
By calling Enqueue and Dequeue in the transaction.
72. What are the events by which we can program "help texts" and display "possible value lists"?
-PROCESS ON HELP-REQUEST (POH).
-PROCESS ON VALUE-REQUEST (POV).
73. What is a matchcode?
A matchcode is an aid to finding records stored in the system whenever an object key is required in an input field but the user only knows other (non-key) information about the object.
74. In what ways we can get the context sensitive F1 help on a field?
- Data element documentation.
- Data element additional text in screen painter.
- Using the process on help request event.
75. What is roll area?
A roll area contains the program's runtime context. In addition to the runtime stack and other structures, all local variables and any data known to the program are stored here.
76. How does the system handle roll areas for external program components?
- Transactions run in their own roll areas.
- Reports run in their own roll areas.
- Dialog modules run in their own roll areas
- Function modules run in the roll area of their callers.
77. Does the external program run in the same SAP LUW as the caller, or in a separate one?
- Transactions run with a separate SAP LUW
- Reports run with a separate SAP LUW.
- Dialog modules run in the same SAP LUW as the caller
- Function modules run in the same SAP LUW as the caller.
The only exceptions to the above rules are function modules called with IN UPDATE TASK (V2 function only) or IN BACKGROUND TASK (ALE applications). These always run in their own (separate) update transactions.
78. What are function modules?
Function modules are general-purpose library routines that are available system-wide.
79. What are the types of parameters in the function modules?
In general, function module can have four types of parameters:
- EXPORTING: for passing data to the called function.
- IMPORTING: for receiving data returned from the function module.
- TABLES: for passing internal tables only, by reference (that is, by address).
- CHANGING: for passing parameters to and from the function.
80. What is the difference between Leave Transaction and Call Transaction?
In contrast to LEAVE TO TRANSACTION, the CALL TRANSACTION statement causes the system to start a new SAP LUW. This second SAP LUW runs parallel to the SAP LUW for the calling transaction.
81. How can we pass selection and parameter data to a report?
There are three options for passing selection and parameter data to the report.
- Using SUBMIT…WITH
- Using a report variant.
- Using a range table.
82. How to send a report to the printer instead of displaying it on the screen?
We can send a report to the printer instead of diplaying it on the screen. To do this, use the keywords TO SAP-SPOOL:
SUBMIT RSFLFIND…TO SAP-SPOOL DESTINATION 'LT50'.
83. How can we send data to external programs?
Using SPA/GPA parameters(SAP memory).
Using EXPORT/IMPORT data (ABAP/4 memory)
84. What are SPA/GPA parameters (SAP memory)
SPA/GPA parameters are field values saved globally in memory. There are two ways to use SPA/GPA parmeters:
By setting field attributes in the Screen Painter.
By using the SET PARAMETER or GET PARAMETER statements.
BDC
1. What is full form of BDC Session?
Batch Data Communication Session.
2. What are the steps in a BDC session?
The first step in a BDC session is to identify the screens of the transaction that the program will process. Next step is to write a program to build the BDC table that will be used to submit the data to SAP. The final step is to submit the BDC table to the system in the batch mode or as a single transaction by the CALL TRANSACTION command.
3. How do you find the information on the current screen?
The information on the current screen can be found by SYSTEM STATUS command from any menu.
4. How do you save data in BDC tables?
The data in BDC tables is saved by using the field name 'BDC_OKCODE' and field value of '/11'.
5. What is the last entry in all BDC tables?
In all BDC tables the last entry is to save the data by using the field name BDC_OKCODE and a field value of '/11'.
6. What is a multiple line field?
A multiple line field is a special kind of field which allows the user to enter multiple lines of data into it.
7. How do you populate data into a multiple line field?
To populate data into a multiple line field, an index is added to the field name to indicate which line is to be populated by the BDC session (Line index).
8. Write the BDC table structure.
BDC table structure
FIELD TYPE DESCRIPTION
Program CHAR (8) Program name of transaction.
DynPro CHAR (4) Screen number of transaction.
DynBegin CHAR (1) Indicator for new screen.
Fnam CHAR (35) Name of database field from screen.
Fval CHAR (80) Value to submit to field.
9. Does the CALL TRANSACTION method allow multiple transactions to be processed by SAP?
No. The CALL TRANSACTION method allows only a single transaction to be processed by SAP.
10. Does the BDC-INSERT function allow multiple transactions to be processed by SAP?
Yes.
11. What is the syntax for 'CALL TRANSACTION'?
CALL TRANSACTION trans [ using bdctab MODE mode ].
Three possible entries are there for MODE.
A - Show all screens.
E - Show only screens with errors.
N - Show no screens.
