HI

1.What is the advantage of structures ?How du u use them in the Abap Pgms?

Advantage of Strucures :

You use structures in ABAP programs to group work areas that logically belong together. Since the elements of a structure can have any data type, structures can have a large range of uses. For example, you can use a structure with elementary data types to display lines from a database table within a program.

Just like tables you have to declare in the program there is no such difference

2.what are the exceptions in function module?

A:Exceptions are situations that occur while an ABAP program is being executed, in which normal continuation of the program does not make any sense. Exceptions can be raised either implicitly in the ABAP runtime environment or explicitly in the ABAP program. For example, division by zero leads to an exception in the ABAP runtime environment. It is possible to determine this situation through a query in the ABAP program and to trigger an exception there.

There are two main types of exceptions: those that can be handled and those that cannot be handled.

· Exceptions that can be handled occur in error situations in the runtime environment or in the ABAP program, where the program can continue executing after the ABAP program has handled the exception, without the system ending up in a critical state. If such an exception is not handled, a runtime error occurs.

· The second type of exceptions are those that cannot be handled. These are critical error situations in the runtime environment. Handling with ABAP means is not possible and they always cause a runtime error.

As of Release 6.10, exceptions and their handling are generally based on exception classes. This concept covers the functions of the preceding concepts, enhances them, and thus replaces them.

internal tables are generally of two types only.

1. INTERNAL TABLES WITH HEADER LINE

2. INTERNAL TABLES WITH OUT HEADER LINE

for internal tables with out header line u need to explicitly create a work area and do record processing from it. where as for internal tables with header line a header is created for u while creating an internal table.

n one of dictionary objects are internal table types

1. standard

2. sorted

3. hashed

1. standard: tables which u use frequently.

follows index and allows data with out any condition

for most situations

2.sorted: while entering data only data is sorted

follows index and keys are used as index.

retreiving data from this table is faster than standard tables

3.hashed tables: uses a hashed algorithm for logic

no index n keys used

fatser than remaining two tables for accessing data

You should declare your internal tables like so.

Types: begin of ttab,

fld1 type c,

fld2 type c,

end of ttab.

data: itab type table of ttab.

data: wa like line of itab.

5.Sales no is 1 ,2 ,3 is there delivery no is 4 ,5,6 is there How to write select statement?

A: Declare your sales No & delivery no in an internal table and then use this write statement

write:/ 'Sales No' itab1.

write:/ 'delivery no' itab2.
