ABAP System Fields

Introduction

ABAP Cloud enabled system fields and date functions.

• Decoupled from coding
• ABAP Cloud best practices
• Testable (Injector Pattern)

Fields and Functions

Via this article you can get more informations to the actual structure and functions.

Date Functions

In the newest classes we utilize I_CalendarDate to give easy and fast access to date functions. You will find methods for often used calculation methods.

Example

Start in the constructor to create the instance and assign it to an attribute of the class, so your Unit Test should stay stable. We can override the "SY" with this method.

sy = zcl_syst=>create( ).

Using as SY-SUBRC in a function:

AUTHORITY-CHECK OBJECT 'S_APPL_LOG'
                ID 'ACTVT' FIELD '02'.

RETURN xsdbool( sy->return_code( ) = 0 ).

Using as SY-UNAME in a IF statement:

IF sy->user_id( ) = 'TECHUSER'.
  RETURN abap_true.
ELSE.
  RETURN abap_false.
ENDIF.

Creating a timestamp inline:

DATA(actual_time) = sy->timestamp_long( ).

Retrieve information about the weekday:

DATA(today) = sy->date_functions( ).
DATA(weekday) = today->get_weekday( ).

DATA(weekday_new) = sy->date_functions( )->get_weekday( ).
