SAP ABAP Interview Questions and Answers

1) What is SAP ABAP?

2) Describe the distinction between transparent tables and pool tables.?

Transparent tables: They are one-to-one relationships with the database table. Its arrangement matches one database field.

Pooled tables: They have a one-to-one relationship with the database table. Database storage is where pooled tables are kept.

The Basic List

a) is for basic reports.

b) Statistics: Average, Percent, etc.

c) Ranking List: Applied to analytical reports

3) When you refer to programming for batch data communications, what do you mean?

BDC is an automated process that imports external or large-scale data into the SAP system. The main part of the transfer is the "queue file," which gathers data via groups and batch input programs connected to "sessions."

4) What are the data classes called?

The following classes comprise the data classes.

Master Data: This class's data rarely changes.

Transaction Data: In this class, the data is subject to frequent changes.

Organization Data: This data is entered into the system during system configuration and is customized. Seldom is it altered.

System Data: The R/3 system utilizes this data.

5) What are the internal tables made of?

Internal tables are only created during program execution. In addition to rearranging database table content to better suit user needs, it is utilized for table computations on subsets of database tables.

6) What is the order in which the functional modules are used in the BDC?

BDC programming requires the sequential use of three functional modules to successfully transfer data. They are

a) BDC Open Group

b) BDC_INSERT

c) BDC_CLOSE_GROUP

7) What is a foreign key relationship?

To guarantee data consistency, foreign keys are employed. It is necessary to clearly define the relationship between the tables at the field level. To make sure there are no discrepancies, newly entered data should be compared to the already-existing data. It is necessary to specify the cardinality when defining a foreign key relationship.

8) What distinguishes a table from a structure in a data dictionary in ABAP?

The distinction in ABAP between a structure and a table

A table can physically hold data, but a structure cannot.

b) A table may have a primary key, but the structure does not

c) The structure lacks the technical attribute, but the table may

9) How do you use smart forms?

In SAP systems, forms intended for mass printing are created and managed using smart forms. SAP Smart Forms can be used with a printer, fax machine, email client, or the Internet as an output medium (by using the generated XML output).

10) Which parts make up SAP scripts?

1. An editor for entering and editing the lines of text

2. sets of styles and layouts for printing layout. These are generated using the relevant maintenance transactions, separate from the individual texts, and subsequently assigned to the texts.

3. One of the main output modules is the composer. From the outside, the SAP script composer is invisible.

4. An interface for programming that lets you control the output of layout sets from within your programs and incorporate SAP script components into your application programs

5. Several database tables to store layout sets, styles, and texts

11)How is a "table cluster" created?

a) Choose object type Table in the ABAP dictionary, type the name of the table, and then select Create.

b) The table's field maintenance screen appears. Sort of table Table that is transparent; make it the default

c) Complete the required fields on the Attributes page for the delivery classified and brief description. Next, specify the table's fields.

d) Continue as if you were making a transparent table. Save your entries now.

e) Select the category of the EXTRAS Change table now.

f) You must choose between the "Cluster table" and "Pooled table" table types when a dialogue box appears.

g) Go back to the table's field maintenance screen after choosing it. In addition to the standard fields, the Attributes tab page displays the name of the cluster or field pool.

h) At this point, type the name of the table pool or cluster that you wish the cluster table to be assigned to.

12)How can the data be formatted before a report's statement is written?

It is possible to format the report output by utilizing the loop event.

a) initially

b) at the new

c) Finally

13) Explain what ABAP's ALV programming is. When does ABAP use this grid?
