SAP Note Number: 953823 says string not supported in FM ??

Question

Hello Friends
I am desperately trying to findout how to send a variable length string from XI and save it in a table.
However, SAP Note Number: 953823 says that STRING is not supported in FM but the work around it suggests is as follows:
========================================================
The only work around for this is :
To wrap the Function module used in function control with the custom function module,which substitutes the STRING parameter with CHAR datatype.
========================================================
But the problem is that for CHAR datatype you have to give the field length, the requirement I have is to send a VARIABLE LENGTH data.
Could some one help me in understanding how this can be achieved?
Thanks a lot in advance

Interesting question.  Maybe I don't completely understand.  When you say store it in a table, do you mean a database table or an itab?
I seem to be able to pass a string to a FM.  Am I doing something wrong?
I created a type of string called "ZTYSTR".
I then created this FM.
*"*"Local Interface:
*"  IMPORTING
*"     REFERENCE(I_STR) TYPE  ZTYSTR
  DATA:
     l_string   type string.
  l_string = i_str.
ENDFUNCTION.
Then I call the function module as such.
REPORT zz_temp.
DATA: g_str  TYPE string VALUE 'Hello World'.
CALL FUNCTION 'Z_TEMP'
  EXPORTING
    i_str = g_str.
Debugging the FM, it says that both the parameter and local variable are of type string.
