problem in structure start with charecter type

[Former Member]

i am doing a upgrade of an abap program which is written in 4.6 to ecc 6.0 i am facing a unicode error problem

in the old program there is a sap standrad structure called arc_buffer so in this program they have used the structure as

below code

PERFORM read_file USING handle_tab_wa-offset record_len

CHANGING arc_buffer(record_len)

error_handling

p_message.

so when it is used as arc_buffer(record_len) system is giving unicode error like

'' the structure arc_bufffer(record_len) does not start with a charecter type field'

as the structure is sap standard i think i cannot change the stadard structure so what should be done to get out of this error.

thank you very much sadra for your help & i hope u could me help in solving my unicode problems & u can also give me any information reg this unicode problems

You can convert arc_buffer to char string before passing it to subroutine.

hi manish thanks for ur replie

can u tell me how can you convert the standard sap structure to char

i will be waiting for ur replie

Hello,

Try something like this,

data: begin of lv_buffer,
         RCSZK(2) type c,
        RNAME type RKZ_DBNA,
        CHECKSUM(4) type c,
        FLAGS type CHAR08,
        SEGMENT type MAX_SEGM,
        end of lv_buffer.

move-corresponding arc_buffer to lv_buffer. 

* Use SCMS_BIN_TO_TEXT to convert arc_buffer-RCSZK and CHECKSUM to char type 

PERFORM read_file USING handle_tab_wa-offset record_len
CHANGING arc_buffer(record_len)
error_handling
p_message.

move-corresponding lv_buffer to arc_buffer. 

* Use SCMS_TEXT_TO_BIN again  to convert arc_buffer-RCSZK and CHECKSUM to raw type

Hi Vik,

How did you get the structure of arc_buffer ? The OP has not provided the details in his post !!

Cheers,

hello vikranth

i have tried to change the data type to Charecter type using fm but it doesnt change

CALL FUNCTION 'SCMS_BIN_TO_TEXT'

EXPORTING

bin_line = arc_buffer-rcszk

• IMPORTING

• TEXT_LINE =

• EXCEPTIONS

• FAILED = 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.

if sy-subrc = 0.

write: 'successful'.

ENDIF.

elinuk,

did you see Suhas remark/question?

Anyway, you should have a look at documentations how to migrate programs to unicode: [SAP library - ABAP and Unicode|http://help.sap.com/saphelp_nw2004s/helpdata/en/62/3f2cadb35311d5993800508b6b8b11/frameset.htm]

To help you a little bit, I think this one might help you more: http://help.sap.com/saphelp_nw2004s/helpdata/en/79/c554d3b3dc11d5993800508b6b8b11/frameset.htm

You should provide the structure details of the arc_buffer for better analysis of your problem.

In Non-UC systems you could use offsets on structures ( like you do on character / string variables ). Although this is not a good programming practice.

In UC systems you cannot use offsets on non-character variables b'coz of which you are getting this error.

There is no standard solution to this problem & needs to be handled on a case-to-case basis. Debug the code in the non-UC system & check what the code is doing with the offset on the structure & try to replicate the same.

BR,

Suhas

[kesavadas_thekkillath]

the structure arc_buffer has following fields

RCSZK

RNAME

CHECKSUM

FLAGS

SEGMENT

so in the routine

PERFORM read_file USING handle_tab_wa-offset record_len
CHANGING arc_buffer(record_len)  "here just use it like arc_buffer-<field_name>(record_len) 
error_handling
p_message.

or before calling the perform statement

data:lv_string type string.

call method cl_abap_container_utilities=>fill_container_c

exporting

im_value = arc_buffer

importing

ex_container = lv_string

exceptions

illegal_parameter_type = 1

others = 2.

PERFORM read_file USING handle_tab_wa-offset record_len
CHANGING lv_string(record_len)  "here just use it like arc_buffer-<field_name>(record_len) 
error_handling
p_message.
