New syntax for append- VALUE (new syntax 7.4+) in ABAP

* We use APPEND statement to insert the records at the last of the internal table.

* In SAP ABAP new syntax, we can use VALUE expression instead of APPEND statement.

* Value expression is a powerful mechanism to declare as well as initialize the internal

tables.

* It is a powerful utility where we can achieve the result with minimal coding.

* Value expression is of 2 types. 

    - Define the type before using it with VALUE keyword. The type defined is structure type or table type.

    - Using # character for type and use it with VALUE keyword.
