What is Table? Table is a logical structure for storing data. Table is the set of rows and columns that are logically related. Table can be defined independent of the database in ABAP dictionary. The table fields are defined with the database independent elementary data types and lengths. The physical table definition created in the […]
What is View? View is a logical representation of summarized data from one or more tables. The view structure can be defined by specifying table names and required field names from the joined tables.

What is Lock Objects? Lock mechanism allows simultaneous accessing of same data records by two or more users at the same time. Functional Modules are responsible for set and release the locks.

What is Internal Table? Internal table is a temporary table that is created and used during the program execution and deleted before the program terminated.

WHILE loop executes the block of statements until the specified condition is false. The block of statements can gets executed any number of times as long as the condition is true.
In while loop, condition is validated before executing the block of statements. If the condition is false for the first time, no statements in the loop gets executed.
Internal tables used during the program execution for processing the data dynamically. So, the internal table should be created in the program where it is using.
DO loop executes the block of statements until the specified number of times. DO loop is an unconditional looping statement.
