CALL FUNCTION - parameter_tables
Syntax
... [PARAMETER-TABLE ptab]
[EXCEPTION-TABLE etab]... .
Extras:
1. ... PARAMETER-TABLE ptab ...
2. ... EXCEPTION-TABLE etab ...
Effect
These additions use the special internal tables ptab and etab
to assign actual parameters to the formal parameters of the function module and return values to the non-class-based exceptions.
... PARAMETER-TABLE ptab ...
Effect
PARAMETER-TABLE can be used to assign actual parameters to all formal parameters of the called function module. ptab expects a sorted table of table type ABAP_FUNC_PARMBIND_TAB or of row type ABAP_FUNC_PARMBIND from the type group ABAP. When the statement CALL FUNCTION is executed, the table must contain exactly one row for each non-optional formal parameter; this row is optional for each optional formal parameter. The table columns are:
The columns NAME and KIND form the unique key of the table ptab.
... EXCEPTION-TABLE etab ...
Effect
EXCEPTION-TABLE can be used to assign return values to exceptions of the called function module that are not marked as exception classes in Function Builder. etab expects a hashed table of table type ABAP_FUNC_EXCPBIND_TAB or of row type ABAP_FUNC_EXCPBIND from the type group ABAP. The table can contain exactly one row for each non-class-based exception of the function module when the statement CALL FUNCTION is executed. The table columns are:
The column NAME is the unique key of table etab.
Example
Calls the function module GUI_DOWNLOAD with dynamic pass by parameter The name of the function module is specified in the string func and the interface is supplied with data using the internal tables ptab and etab.
DATA: line TYPE c LENGTH 80,
text_tab LIKE STANDARD TABLE OF line,
filename TYPE string,
filetype TYPE c LENGTH 10,
fleng TYPE i.
DATA: func TYPE string,
ptab TYPE abap_func_parmbind_tab,
etab TYPE abap_func_excpbind_tab.
func = 'GUI_DOWNLOAD'.
filename = 'c:\temp\text.txt'.
filetype = 'ASC'.
