SYSTEM VARIABLE & STRING OPERATIONS????

Let's start with the system variable.

A system variable refers to a predefined variable provided by the SAP system itself. These variables are automatically available for use in ABAP programs and can provide information about the system or the current execution environment.

SYST is the structure for the system field. All the system fields are addressed using the SY field name.

The various system variables?are?as?follows:

SY-SUBRC= System variable for the return code (successful =0 not successful other than 0).

SY-TABIX= It returns the current Line index inside a loop.

SY-INDEX= IT returns the current Line index inside the do and while loop.

SY-DATUM= System variable for?the current?date (Internal format- yyyy-mm-dd).

SY-UNAME = It returns the login name of?the?user.

Let us now read what is string operations.

In SAP ABAP, string operations refer to the various functions and methods available to manipulate strings (sequences of characters). These operations are essential for tasks such as searching within strings, extracting substrings, concatenating strings, converting between different formats, and more. Here are some common string operations in SAP ABAP:

1. CONCATENATE: This keyword is used to concatenate two or more strings together into a single string.

SPLIT: This keyword splits a string into components based on a delimiter and stores them in an internal table.
