SAP ABAP Statement syntax including basic implementation code

See below for details and syntax for specific SAP ABAP statements but also note there are a few basic syntax rules which are valid for writing all ABAP code including:

•  All statements must end with period/full stop (Example: SELECT * from EKKO into it_ekko.)

•  ABAP statements and keywords are not case sensitive (Example: SELECT, Select, select).

•  String values are enclosed within single quotes (Example: ld_string = 'Hello World'.)

•  You can use * or " for commenting purposes. * must be placed at the start of the line and " can be placed any where.

Example using all of the above syntax rules

* The select statement retrieves data from the ekko table
* into an internal table called it_ekko
	Select *
	  FROM ekko              "get data for ekko table
	  into TABLE it_ekko
	 WhERe ebeln = '12345'.  "only retrieves values that match this where clause
"Note: You can use the pretty printer functionality to auto format your code
