ABAP_ALTERNATIVES:
1 static_meth( ).
2 static_meth( a ).
3 static_meth( p1 = a1 p2 = a2 ... ).
4
static_meth( EXPORTING ... IMPORTING ... CHANGING ... RECEIVING
... ).
What does it do? Static call of a method specified by the name
static_meth as a
standalone statement. In the parentheses, the
parameter interface of the method
is supplied with the actual parameters. In the first alternative, no
formal parameters are supplied with actual parameters. The second and
third alternatives are short forms for methods where only the input
parameters are supplied with actual parameters. The fourth alternative
allows all possible formal parameters to be supplied with actual
parameters, and the handling of non-class-based exceptions.
ABAP_ALTERNATIVE_1 static_meth( ).
What does it do? Calls the method
static_meth without pass by parameter. The method can either
have no input parameters or input/output parameters or only optional
input parameters or input/output parameters. An actual parameter is not
assigned to any output parameters or return codes.
Example ABAP Coding Calls a method without parameters.

ABAP_ALTERNATIVE_2 static_meth( a ).
What does it do? This is the short form of:
static_meth( EXPORTING p = a ).
The method static_meth
can have either only one non-optional input parameter p or only
optional input parameters, of which p is defined as the preferred
parameter using PREFERRED PARAMETER . The value of a is
passed to this input parameter; this value can be specified as a data
object, function, or expression.
The method can only have optional input/output parameters. No actual
parameters are assigned to these input/output parameters, any output
parameters, or a return value.
Example ABAP Coding Calls a method with an input parameter

ABAP_ALTERNATIVE_3 static_meth( p1 = a1 p2 = a2 ... ).
What does it do? This is the short form of:
static_meth( EXPORTING p1 = a1
p2 = a2 ... ).
The method static_meth
can have any number of input parameters p1 , p2 , and so on,
which are supplied with the actual parameters a1 , a2 , and
so on. The actual parameters can be specified as a data object,
function, or expression.
The method can only have optional input/output parameters. No actual
parameters are assigned to these input/output parameters, any output
parameters, or a return value.
Example ABAP Coding Calls a method with two input parameters.

ABAP_ALTERNATIVE_4 static_meth( EXPORTING ... IMPORTING ...
CHANGING ... RECEIVING ... ).
What does it do? Calls the method
static_meth with explicit pass
by parameter and the option of handling non-class-based exceptions.
This format can be used to call methods with any number of parameter
interfaces.
Example ABAP Coding Calls a method with explicit pass by parameter.
