Transfering dynamic data structures via RFC

Former Member — Fri, 24 Apr 2009 09:06:10 GMT

Hi there,

I got a quite basic question.

I want to transfer a text String with differing length to a external tool. Since I don't know how long the String will be, I had to set the number of characters to 30.000. Is there a way to transfer dynamic structures?

Obviously the character typ "String" is not allowed for RFC....

Thanks

Oliver

Hi Oliver,

What you can do is to have a table with a field of say 100 characters.

Since this is a table, you can add more lines when the length increases .

YOu can make use of Function module RKD_WORD_WRAP to convert a big string into a table of shorter strings.

Sample usage of this FM:

CALL FUNCTION 'RKD_WORD_WRAP'
     EXPORTING
          TEXTLINE            = L_TEXT
          OUTPUTLEN           = 100

*    IMPORTING
*         OUT_LINE1           =
*         OUT_LINE2           =
*         OUT_LINE3           =
    TABLES
         OUT_LINES           = OUT_LINES
    EXCEPTIONS
         OUTPUTLEN_TOO_LARGE = 1
         OTHERS              = 2
          .

Then pass this OUTLINES to the RFC tables parameter.

Hi,

How about delimiting the set of lines belonging to one string from another set using a string of

'----

' (100 hyphens)

assume that you have a table of strings say it_strings

loop at it_strings.
CALL FUNCTION 'RKD_WORD_WRAP'
     EXPORTING
          TEXTLINE            = IT_STRINGS-STRING
          OUTPUTLEN           = 100

*    IMPORTING
*         OUT_LINE1           =
*         OUT_LINE2           =
*         OUT_LINE3           =
    TABLES
         OUT_LINES           = OUT_LINES
    EXCEPTIONS
         OUTPUTLEN_TOO_LARGE = 1
         OTHERS              = 2
          .
IF SY-SUBRC <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
append lines of out_lines to it_final.
it_final-data = '---------------------------------------'.
append it_final.
clear it_final.
endloop.
