Generic fm for Unicode Conversion ?

[former_member194669]

All,

I have requirement to write common function module to convert data from itab --> string and string --> itab in unicode environment. I am planning to use class cl_abap_container_utilities and methods

1). FILL_CONTAINER_C

2). READ_CONTAINER_C

The following is the function module for string --> itab

function z_test_unicode.
*"----------------------------------------------------------------------
*"*"Local Interface:
*"  IMPORTING
*"     REFERENCE(XINPUT) TYPE  STRING OPTIONAL
*"  EXPORTING
*"     REFERENCE(XOUTPUT) TYPE  STANDARD TABLE
*"----------------------------------------------------------------------
  class cl_abap_container_utilities definition load.
  call method cl_abap_container_utilities=>read_container_c
    exporting
      im_container           = xinput
    importing
      ex_value               = xoutput
    exceptions
      illegal_parameter_type = 1
      others                 = 2.
endfunction.

and i am calling this in the program

report zaRs
       no standard page heading
       line-size 255.

data: begin of itab occurs 0,
        detail(2047)   type c,
      end   of itab.

data: begin of i_yatt occurs 0.
data: mandt     like sy-mandt.
data: docno     like vbak-vbeln.
data: end of i_yatt.

move '0301000' to itab-detail.
append itab.

loop at itab.
call function 'Z_TEST_UNICODE'
 EXPORTING
   XINPUT        = itab-detail
 IMPORTING
   XOUTPUT       = i_yatt.
 append i_yatt.
endloop.

But i am getting DUMP

"Type conflict when calling a function module."

How to overcome this , i need to work with all input length and all xoutput internal tables?

Any info?

inside the loop you pass the itab-detail value to one string variable and pass it to function module.

[former_member194669]

Alagu,

It not nothing related to loop. real problem is type conflict error in INPUT and OUTPUT . My input parameter always not of string. length varied every instance.

and the OUTPUT internal table is also not static it will get differed on each call

Hi a®s,

i tried its mainly of type conflict with input and output. check my previous code.

Try like this

REPORT ZTEST_FUNCTION

*report zaRs

no standard page heading

line-size 255.

data: begin of itab occurs 0,

detail(2047) type c,

end of itab.

types: begin of w_yatt ,

mandt like sy-mandt,

docno like vbak-vbeln,

end of w_yatt.

data: i_yatt type table of w_yatt,

wa_yatt type w_yatt.

move '0301000' to itab-detail.

append itab.

data v_string type string.

loop at itab.

clear v_string.

v_string = itab-detail.

break-point.

call function 'ZTEST_FM'

EXPORTING

XINPUT = v_string

IMPORTING

XOUTPUT = i_yatt.

• append wa_yatt to i_yatt.

endloop.

as XINPUT is type string, why dont you make itab-detail also of type string ?

Isn't that the reason why tis giving a dump ?

[former_member194669]

Sugamol,

I cannot declare the ITAB-DETAIL as string in every code . and also i cannot able to do like Alagu asked for

move data v_string type string. 

This is where i stuck.

Do like this.

data v_string type string.

loop at itab.

clear v_string.

v_string = itab-detail. " move your detail value to v_string

call function 'ZTEST_FM'

EXPORTING

XINPUT = v_string

IMPORTING

XOUTPUT = i_yatt.

Its working for me. check again

In you function, make the importing parameter without any type, and then move the importing parameter to a STRING type field internally.

function z_test_unicode.
*"----------------------------------------------------------------------
*"*"Local Interface:
*"  IMPORTING
*"     REFERENCE(XINPUT) 
*"  EXPORTING
*"     REFERENCE(XOUTPUT) TYPE  STANDARD TABLE
*"----------------------------------------------------------------------

data: lv_string type string.

lv_string = xinput.

  class cl_abap_container_utilities definition load.
  call method cl_abap_container_utilities=>read_container_c
    exporting
      im_container           = lv_string    "<--- Change here
  importing
      ex_value               = xoutput
    exceptions
      illegal_parameter_type = 1
      others                 = 2.


endfunction.

Oh, and also, if XOUTPUT is typed as a STANDARD TABLE, then this is wrong as well....

loop at itab.
call function 'Z_TEST_UNICODE'
 EXPORTING
   XINPUT        = itab-detail
 IMPORTING
   XOUTPUT       = i_yatt.    "<-- this represents the header line, not the table
 append i_yatt.    
endloop.

So you should actually have a sepearete workaread for you header line, but if you don't want to do that, then you need brakets here I think.

loop at itab.
call function 'Z_TEST_UNICODE'
 EXPORTING
   XINPUT        = itab-detail
 IMPORTING
   XOUTPUT       = i_yatt[].    "<--Brakets to specify the table body
 append i_yatt.       "<-- and you wouldn't need this
endloop.

Also, I'm not 100% sure that the STATIC method within the function will actually bring back a table, hence making all this invalid as well..

Yes correct. either you need to declare seperate work area or brackets you need to add. and no need for append there.

[former_member194669]

Rich you are right.

after the cl_abap_container_utilities=>read_container_c system is not returning the value.

May be i need to look some other alternative.
