What is a selection screen in ABAP?
A selection screen is the input screen a classical report program automatically displays before running,
letting the user specify parameters (like a date range or a specific customer ID) that control what data the
report selects and processes — declared with PARAMETERS and
SELECT-OPTIONS statements.
REPORT z_customer_report. PARAMETERS: p_land TYPE land1 DEFAULT 'US'. SELECT-OPTIONS: s_kunnr FOR kna1-kunnr. START-OF-SELECTION. SELECT * FROM kna1 INTO TABLE @DATA(lt_customers) WHERE land1 = @p_land AND kunnr IN @s_kunnr.
SAP automatically generates the actual screen (labels, input fields, a "range" selection widget for
SELECT-OPTIONS) just from these declarations — the developer doesn't need to manually design
the screen layout for a basic selection screen, which is a significant convenience compared to building a
fully custom input screen from scratch.
What does PARAMETERS and SELECT-OPTIONS let you declare?
Does the developer need to manually design the selection screen's layout?
