What is foreign key relationship?
A relationship which can be defined between tables and must be explicitly defined at field level. Foreign keys are used to ensure the consistency of data. Data entered should be checked against existing data to ensure that there are now contradiction. While defining foreign key relationship cardinality has to be specified. Cardinality mentions how many dependent records or how referenced records are possible.

What are indexes?
Indexes are described as a copy of a database table reduced to specific fields. This data exists in sorted form. This sorting form ease fast access to the field of the tables. In order that other fields are also read, a pointer to the associated record of the actual table are included in the index. The indexes are activated along with the table and are created automatically with it in the database.

What is ALV programming in ABAP? When is this grid used in ABAP?
ALV is Application List viewer. Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output. Cases arise in sap when the output of a report contains columns extending more than 255 characters in length. In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. This is a very efficient tool for dynamically sorting and arranging the columns from a report output. The report output can contain up to 90 columns in the display with the wide array of display options.

What are logical databases? What are the advantages/ dis-advantages of logical databases?
To read data from a database tables we use logical database. A logical database provides read-only access to a group of related tables to an ABAP/4 program. Advantages: i)check functions which check that user input is complete, correct,and plausible. ii)Meaningful data selection. iii)central authorization checks for database accesses. iv)good read access performance while retaining the hierarchical data view determined by the application logic. dis advantages: i)If you donot specify a logical database in the program attributes,the GET events never occur. ii)There is no ENDGET command,so the code block associated with an event ends with the next event statement (such as another GET or an END-OF-SELECTION).

How can I make a differentiation between dependent and independent data?
Client dependent or independent transfer requirements include client specific or cross client objects in the change requests. Workbench objects like SAPscripts 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.

What is the difference between macro and subroutine?
Macros can only be used in the program the are defined in and only after the definition are expanded at compilation / generation. 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). A FUNCTION is (more or less) a subroutine that is called external. Since debugging a MACRO is not really possible, prevent the use of them (I’ve never used them, but seen them in action). If the subroutine is used only local (called internal) use a FORM. If the subroutine is called external (used by more than one program) use a FUNCTION.

What is the differences between structure and table in data dictionary in ABAP?
Structure and table both are 2/2 matrices but there are many differences between table and structure.
1. Table can store the data physically but a structure dose not store.
2. Table can have primary key but a structure dose not have.
3. Table can have the technical attribute but a structure dose not have.
structure doesn't contain technical attributes.
structure doesn't contain primary key.
structure doesn't stores underline database level.

What is the difference between collect and sum?
SUM.
When processing an internal table in a block starting with LOOP and concluded by ENDLOOP , SUM calculates the control totals of all fields of type I , F and P (see also ABAP/4 number types ) and places them in the LOOP output area (header line of the internal table or an explicitly specified work area).
When you use SUM in a LOOP with an explicitly specified output area, this output area must be compatible with the line type of the internal table.When using LOOP to process a sorted extract (see SORT ), the control total of f at the end of the group appears in the field SUM(f) - - if f is type I , F or P .
COLLECT.
COLLECT is used to create unique or compressed datsets. The key fields are the default key fields of the internal table itab .
If you use only COLLECT to fill an internal table, COLLECT makes sure that the internal table does not contain two entries with the same default key fields.
If, besides its default key fields, the internal table contains number fields,the contents of these number fields are added together if the internal table already contains an entry with the same key fields.
If the default key of an internal table processed with COLLECT is blank, all the values are added up in the first table line.
If you specify wa INTO , the entry to be processed is taken from the explicitly specified work area wa . If not, it comes from the header line of the internal table itab .
After COLLECT , the system field SY-TABIX contains the index of the - existing or new - table entry with default key fields which match those of the entry to be processed.
COLLECT can create unique or compressed datasets and should be used precisely for this purpose. If uniqueness or compression are unimportant, or two values with identical default key field values could not possibly occur in your particular task, you should use APPEND instead. However, for a unique or compressed dataset which is also efficient, COLLECT is the statement to use.
If you process a table with COLLECT , you should also use COLLECT to fill it. Only by doing this can you guarantee that the internal table will actually be unique or compressed, as described above and COLLECT will run very efficiently.
If you use COLLECT with an explicitly specified work area, it must be compatible with the line type of the internal table.

In events start-of-selection is default event. When we have to use this event explicitly? Why?
The default event in the ABAP is Start-of-selection.We have to call explicitely this event when you are writing other than ths event , that is when you write AT SELECTION-SCREEN EVENTS OR INITIALIZATION EVENT etc,you have to explicitely mention the Start-of-selection event while you are writing the logic.
Before these events called ,all the code you have written come into this default Start-of-selection screen event.

How do you connect to the remote server if you are working from the office for the client in remote place.
WAS web application server or ITS are generally used for this purpose. 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, intermidiate documents which carry the data you want to transfer or the documents you want to transfer, these IDOC are interpretted by the system at the recieving end with the message class with which it is bound with. If you want to logon a system which is very distant..then remote login can be used this depends on the internet speed.

Explain about roll area , Dispatcher, ABAP-Processor.
Answer1:
Roll area is nothing but memory allocated by work process. It holds the information needed by R/3 about programs execution such as value of the variables.
Dispatcher :All the requests that come from presentation server will be directed first to dispatcher. Further dispatcher sends this requests to work process on FIFO(First In and First Out) basis.
Answer2:
Dispatcher recieves the request from client and assigns the request to one of the work process.
Roll area: Each workprocess works in a particular memory that memory is known as Role Area, which consists of User context and session data.
ABAP- Processor :is an interpretor which can execute logic

You can use field symbols to make the program more dynamic. In this example the name of a table control is substituted by a field symbol. Thus you cal call the form with any internal table, using the name of the table control as a parameter.
Example
form insert_row
using p_tc_name.
field-symbols <tc> type cxtab_control. "Table control
assign (p_tc_name) to <tc>.
* insert 100 lines in table control
<tc>-lines = 100.
Answer2:
fieldsymbol has the same concept as pointer in c,
fieldsymbol don't point to a data type like char, num instead of that it points to the memory block. the syntax for fieldsymbol is
FIELD-SYMBOL <N>.
EG. FOR FIELD SYMBOL.
DATA: DAT LIKE SY-DATUM,
TIM LIKE SY-UZEIT,
CHAR(3) TYPE C VALUE 'ADF'.
FIELD-SYMBOL : <FS>.
MOVE DAT TO <FS>.
WRITE:/ <FS>.
MOVE TIM TO <FS>.
WRITE:/ <FS>.
MOVE CHAR TO <FS>.
WRITE:/ <FS>.
The output will be
Today's date
current time

What is the step by step process to create a table in data dictionary?
Answer1
steps to create database tables
1.go to se11
2.give name the database table
3.give short description for the table
4.Give delivery class name as A and data browser / table view maint as Display/maintenence allowed
5.select fields tab
6.give field name data type(user defined element type/built-in-type),short text
7.select technical settings tab ,give data class as appl0 and size category as 0
8.save it
9.go utillities menu click table contents select create and enter the field values then select display in table contents and u can view the table values with field lables
Answer2
bottom to top approach:
_________________________
step 1:
creating a domain:
*se11,select the object type as domain ,name it ,create,description,enter the datatype and length(size),save ,activate
step2:
creating a dataelement;
se11,select the object type as :date element,name it ,create,desc,assign it with a domain what we created now,save,activate it.
step3:
creating a table;
se11,select the object type as table,name it, create,
enter the field name and assign it with the data element instead of assigning a datatype to it,
like this create req fields:
on behalf of this:
table maintainence:
assign the type of the table ie.,A C G L S
NEXT
maintaince:
allowed,not allowed ,allowed with restricions
