The COMMAND-FCode the USER : in the push button can be worked before, must TABLES sscrfields. Statement structure is SSCRFIELDS ABAP dictionary data interfaces to define workspace. When the user clicks a button triggers the AT SELECTION-SCREEN event, and code function the FCode will be stored sscrfields-ucomm field.
PARAMETERS: A1(10) TYPE C,

SELECT-OPTIONS selcrit FOR {dobj|(name)}
The statement generates a named selcrit selected within condition table, the global table structure type following rows:
The DATA: the BEGIN. OF selcrit the OCCURS 0,
Sign (1), "C Sign length field is a data type which is 1-bit flag, allowed values. The I and E
Option (2)," data type OPTION field is C, length is 2, OPTION comprising operator selecting "
low-MATNR the LIKE Mara, the data type of the field f low of the same type, the value range is selected and specified lower bound
high LIKE mara-matnr," f the same data type field type HIGH the value range is selected and specified upper bound
END oF selcrit.

8. SELECTION-SCREEN FUNCTION KEY n [ldb_additions]. the application toolbar contains five inactive pushbuttons, to which the function codes FC01 to FC05 are assigned. This statement activates the pushbutton of the function code FC0n, whereby a value between 1 and 5 must be entered for n.
