How can I change the parameter's type dynamically

Former Member — Fri, 19 Sep 2008 07:23:25 GMT

Hello,everybody!

I'm creating a fuction modul or a class's method. But met a problem.I want to change the exporting parameter's type dynamically.

Here is what I want to do.

import data:

stru_name (structure name) dictionary table

indata (input data) string

output

outdata (output data)

The output data will be divided according to the structure of stru_name.

For example:

structure(a(3),b(3),c(3))

indata(123456789)

u2192outdata(123,456,789)

structure(a(2),b(3),c(4))

indata(123456789)

u2192outdata(12,345,6789)

Can anybody give me some advices?

I will appreciate your help.

Thanks.

Chen.

Make the parameter type ANY. Then you can pass data of any structure.

Hello Junhua,

Don give any type for the parameters in the function module to make it generic.

Hello Sourav,Farzan

Thanks for your reply.

I have give any type for the output parameter .

But at the end of my source ,how I move the data to the output parameter.

Here is my source.

FUNCTION z_divide_data_by_stru.

CREATE DATA dy_stru TYPE (stru_name).

IF sy-subrc <> 0.

ENDIF.

DO.

ASSIGN COMPONENT sy-index

OF STRUCTURE <dyn_stru> TO <dyn_field>.

READ TABLE res_dfies INTO wl_dfies INDEX sy-index.

wa_offset = wl_dfies-offset.

wa_length = wl_dfies-leng.

<dyn_field> = i_data+wa_offset(wa_length).

IF sy-subrc <> 0.

EXIT.

ENDIF.

ENDDO.

WRITE <dyn_stru> TO o_data. -

>Here is my problem....

ENDFUNCTION.

Can you give me some other advice?
