When is this grid used in ABAP? To enhance the output of the report, SAP provides a set of ALV function modules which can be used, and it also improves the functionality and readability of any report output. It is an efficient tool used for arranging the columns in a report output.
Check Table: A dependent table is called a foreign key table, and the referenced table is called the check table. Each key field of the check table corresponds to a field in the foreign key table. These fields are called foreign key fields. One of the foreign key fields is designated as the check field for checking the validity of values. The key fields of the check table can serve as input help for the check field.
Value Table: Prior to Release 4. This is no longer possible, primarily because unexpected results could occur if the value table had more than one key field. It was not possible to restrict the other key fields, which meant that the environment of the field was not considered, as is normal with check tables.
In cases where this kind of value help was appropriate, you can reconstruct it by creating a search help for the data elements that use the domain in question, and using the value table as the selection method. Check table will be at field level checking. Value table will be at domain level checking ex: Data is permanently stored in tables in the database. Database tables are generated from them. It contains data temporarily during program run-time.
No Database tables are generated from it. What Are Lock Objects? Reason for Setting Lock: Suppose a travel agent want to book a flight. The customer wants to fly to a particular city with a certain airline on a certain day.
The booking must only be possible if there are still free places on the flight. To avoid the possibility of overbooking, the database entry corresponding to the flight must be locked against access from other transactions. This ensures that one user can find out the number of free places, make the booking, and change the number of free places without the data being changed in the meantime by another transaction.
Explain the relationship between a functional area, user group and query when developing queries using the SAP Query tool? A functional area is typically — based on a logical database but can be any table and fields within that table. Functional areas are also assigned for the user group allowing users to create and start queries based on the data in that functional area. Multiple functional areas can be assigned to a user group and a functional area can be assigned to several different groups.
What ABAP statement will trigger list generation?
Upon completion of the program, the list is output. The system will generate some standard headings for list output that includes the program name and a page number in the heading.
When do we use End-of-selection? In the HR-ABAP code, data is retrieved in the start of selection event and printing on the list and all will be done at the end of the selection event. What is table buffer? Which type of tables used this buffer? Over here, buffer means memory area, table buffer means the table information is available on the application server. When you call data from database table, it will come from application server.
Transparent tables and pool tables are buffered, while cluster table cannot be buffered. What are the differences? In SE38 , you can create programs and view online reports and basically do all the development of objects in this editor. In SE80, there are additional features such as creating packages, function group, module pool, classes, programs and BSP applications.
Explain the difference between dialog program and a report? A report is an executable program; dialog is a module pool program. It has to be executed via a transaction only.
Dialog programming is used for customizations of screens. To synchronize access of several users using same data Lock objects are used. What are the ways you can do the tuning? What are the major steps will you use for these? What are internal tables? How do you get the number of lines in an internal table? How to use a specific number occurs statement? ANS:- i It is a standard data type object which exists only during the runtime of the program. They are used to perform table calculations on subsets of database tables and for re-organising the contents of database tables according to users need.
How do you take care of performance issues in your ABAP programs? Performance of ABAPs can be improved by minimizing the amount of data to be transferred.
The data set must be transferred through the network to the applications, so reducing the amount OF time and also reduces the network traffic.
A Field Symbol does not physically reserve space for a field,but points to a field which is not known until runtime of the program. What are datasets? They are used for file handling in SAP. How to find the return code of a statement in ABAP programs? Have you used SAP supplied programs to load master data? What are the techniques involved in using SAP supplied programs? Do you prefer to write your own programs to load master data? What are logical databases?
ANS:- To read data from a database tables we use logical database. Because Logical database knows how the different tables relate to each other,and can issue the SELECT command with proper where clause to retrieve the data.
What specific statements do you using when writing a drill down report?
What are different tools to report data in SAP? What all have you used? What are the functional areas? User groups? Have you used them? What do you do when the system crashes in the middle of a BDC batch session? What do you do with errors in BDC batch sessions?
ANS:- We look into the list of incorrect session and process it again.
Its structure corresponds to single database field. Pooled tables: It has many to one relation with the table in the database. Pooled tables are stored at the database level. Update function modules are classified as either V1 or V2. Which type of update is performed first and in what mode Asynchronously, Synchronously or locally can each type be processed in? V1 updates take priority over V2 updates and are therefore processed prior to V2 updates.
V1 updates can be performed asynchronously, synchronously or locally.
V2 updates always run asynchronously. The modification assistant is a tool introduced in release 4. The modification assistant can be triggered through the ABAP editor and it will assist in logging modifications for any changes that are made to the system. What statement will be found in an SAP application program that implements a function module exit? Function module exits will exist in some SAP application programs to allow a customer to add some functionality to the SAP program.
Search the SAP application program globally looking for the following search string: A transaction variant is a set of screen variants that is used to predefine screen behavior and defaults.
Fields, subscreens and full screens that may not be required by a user can be suppressed from that users view through the use of variant functionality. Screen layouts can be modified by inserting buttons, value helps, moving objects, inserting screens and much more.
List some of the many different ways that the SAP standard functionality can be changed by a customer? Examples of these different approaches for changing the standard are as follows: All other techniques should be explored before modifying an SAP object.
What are logical databases? To read data from a database tables we use logical database. Data along with the action is stored in session ie data for screen fields, to which screen it is passed, program name behind it, and how next screen is processed.
Download of the source file template. Modification of the source file. Upload of the data from the source file. Smart Forms allows you to create forms using a graphical design tool with robust functionality, color, and more.
Client dependent or independent transfer requirements include client specific or cross client objects in the change requests. Workbench objects like SAP scripts are client specific, some entries in customizing are client independent. If you display the object list for one change request, and then for each object the object attributes, you will find the flag client specific. If one object in the task list has this flag on, then that transport will be client dependent.
Subroutines FORM can be called from both the program the are defined in and other programs. A MACRO is more or less an abbreviation for some lines of code that are used more than once or twice. A FORM is a local subroutine which can be called external. If the subroutine is used only local called internal use a FORM. What is the differences between structure and table in data dictionary in ABAP?

TYPE, you assign datatype directly to the data object while declaring. LIKE,you assign the datatype of another object to the declaring data object.
The datatype is referenced indirectly. The 2 editors are se38 and se80 both have the abap editor in place. In se38 you can go create programs and view online reports and basically do all the developmet of objects in this editor. In se80 object navigator there are additional features such as creating packages,module pool , function group ,classes, programs where you can create ur programs and BSP applications.
Report is a executable program Dialog is a module pool program. It has to be executed via a transaction only. Dialog programming is used for customization of screens. How do you connect to the remote server if you are working from the office for the client in remote place. If you are sitting at your office with a server which is in the system and the other server is at the clients place you can generate IDOC, intermediate documents which carry the data you want to transfer or the documents you want to transfer, these IDOC are interpreted by the system at the receiving end with the message class with which it is bound with.
