Syntax Forms

Static form

[CALL METHOD] {meth
              |oref->meth
              |super->meth
              |class=>meth}( { }
                           | { a }
                           | p1 = a1 p2 = a2 ...
                           | {   [EXPORTING p1 = a1 p2 = a2 ...]
                               {{[IMPORTING p1 = a1 p2 = a2 ...]
                                 [CHANGING  p1 = a1 p2 = a2 ...]}
                               | [RECEIVING r  = a ]}
                                 [EXCEPTIONS [exc1 = n1 exc2 = n2 ...]
                                             [OTHERS = n_others]] } ).

Dynamische Form

CALL METHOD {(meth_name)
            |oref->(meth_name)
            |(class_name)=>(meth_name)
            |class=>(meth_name)
            |(class_name)=>meth}
  [PARAMETER-TABLE ptab]
  [EXCEPTION-TABLE etab].

Effect

Calls a method. In the static form, all forms of the parameter list can be placed in brackets; in bracketed parameter lists, you can omit CALL METHOD. In the dynamic form, certain static specifications are possible.

Additions

Specify the Method

• meth - Method meth of the same class.
• oref->meth - Instance method meth of the object referenced by oref.
• super->meth - Method of same name meth in the direct superclass.
• class=>meth - Static method meth of class class.
• (meth_name) - Method contained in meth_name.
• (class_name) - Class contained in class_name.

Specify the Parameters

• ( )
  Short form for the call of a method without passing a parameter.
• ( a )
  Short form for the call of a method, thereby passing a single parameter
  a.
• ( p1 = a1 p2 = a2 ... )
  Short form for the call of a method, thereby passing several parameters
  a1, a2, ...
• EXPORTING p1 = a1 p2 = a2 ...
  Passes actual parameters a1, a2, ... to input parameters p1, p2, ...
• IMPORTING p1 = a1 p2 = a2 ...
  Copies output parameters p1, p2, ... into actual parameters a1, a2, ...
• CHANGING p1 = a1 p2 = a2 ...
  Assigns actual parameters a1, a2, ... to input/output parameters p1, p2, ...
• RECEIVING r = a
  Copies the return value r into the actual parameter a.

Specify the Exceptions

• EXCEPTIONS
  Allows handling of non-class-based exceptions:
  
  exc1 = n1 exc2 = n2 ... - Assigns to the classic exceptions
  exc1, exc2, ... numbers n1, n2, ... for the return value sy-subrc.
  
  OTHERS = n_others - Assigns to all not explicitly named exceptions a number n_others for the return value sy-subrc.

Specify Parameters and Exceptions in Tables

• PARAMETER-TABLE ptab
  Assigns dynamic actual parameters to formal parameters using an internal table ptab of type ABAP_ PARMBIND_TAB.
• EXCEPTION-TABLE etab
  Assigns dynamic return values to non-class-based exceptions using an internal table etab of type ABAP_EXCPBIND_TAB.
