dynamic function module call

[Former Member]

Hi all,

can anybody suggest me how to handle import, export and tables parameters in a dynamic function module call if they are associated with TABLE types.

Hi sam,

for the dynamic function call, you can create whatever data type you need: Define a varfiable, i.e. lr_any type ref to data and a field-symbol type any table.

Then, according to FM interface description, you can

CREATE DATA lr_any TYPE TABLE OF (<structure type>) or
CREATE DATA lr_any TYPE  (<table type>) .

Then

assign lr_any->* to <field-symbol>.

and pass it to function module parameter.

For the pure-character data exchange with external system you may dynamically assign the components to field-symbol, put content into string and concatenate all the strings by tabulator, i.e.

FIELD-SYMBOLS:
  <record> TYPE ANY,
  <field>    TYPE any.
DATA:
  lv_field  TYPE string
  lv_record TYPE string,
  lt_output TYPE TABLE of STRING.

LOOP AT <any> ASSIGNING <record>.
  DO.
    ASSIGN COMPONENT sy-index OF STRUCTURE <record> TO <field>.
    IF sy-subrc = 0.
      lv_field = <field>.
      IF lv_record IS INITIAL.
        lv_record = lv_field.
      ELSE. 
      CONCATENATE lv_record lv_field INTO lv_record
        SEPARATED BY cl_abap_char_utilities=>hoizontal_tab.
      ENDIF
    ELSE.  
      EXIT." DO
    ENDIF.
  ENDDO.
  APPEND lv_record TO lt_output.
  CLEAR lv_record.
ENDLOOP.

This is the way to return data to external call. If you want to receive data from external system, it would be the other way round.
