Unicode type not convertible

[Former Member]

Hi,

Need some help in modifying the code ... I am working on a mass download of data into a texr file from the tables. Few of these tables have fields in decimal or currency and I need to read them into character string. I know the structure of the internal table I read the data into has to exactly match the table structure in Unicode environment. How to add that in the code when I am pulling the tables dynamically and reading their data in a sequential manner. Hence I am getting the above error.

Data: begin of i_list occurs 0,

i_tabledata(2550) type c,

end of i_list.

select * from (v_tabname) into i_list. -

---

> Unicode type not convertible error...

append i_list.

clear i_list.

endselect.

The value of 'v_tabname' comes from the table DD02l dynamically.

Any thoughts?

Thanks,

VG

Hi VG,

It takes a lot of code but it works:

  DATA: lo_structtype type ref to cl_abap_structdescr,
        lo_tabletype  type ref to cl_abap_tabledescr,
        lr_structdata type ref to data,
        lr_tabledata   type ref to data.

field-symbols: <ls> type any,
               <lt> type standard table.

* get the type for the structure
lo_structtype ?= cl_abap_structdescr=>describe_by_name( v_tabname ).
* get the type of the table
lo_tabletype = cl_abap_tabledescr=>create( p_line_type = lo_structtype ).

* create the data
create data: lr_structdata type handle lo_structtype,
                    lr_tabledata type handle lo_tabletype.

* assign the field symbols
assign lr_structdata->* to <ls>.
assign lr_tabledata->* to <lt>.

* select the data
select * from (v_tabname) into <ls>.
append <ls> to <lt>.
endselect.

Thanks,

Erik

Hello Erik,

Doesn't take so much coding you know Check this out:

PARAMETERS: p_tab TYPE tablename OBLIGATORY.

DATA: dref TYPE REF TO data.

FIELD-SYMBOLS: <itab> TYPE STANDARD TABLE.

CREATE DATA dref TYPE STANDARD TABLE OF (p_tab).
ASSIGN dref->* TO <itab>.

SELECT * FROM (p_tab) INTO TABLE <itab> UP TO 10 ROWS.
IF sy-subrc = 0.
  WRITE: / `I've created a dynamic internal table. Yipeee!!!!`.
ENDIF.

Hi,

Thanks I got that part. I am having the problem in reading the entire data into a internal table 'List' from the field symbol. My internal table is a single field of type character. I need to read the data into this internal table for downloading the data into a text file.

Data: begin of i_list occurs 0,

i_tabledata(2550) type c,

• table_rec(255) type c,

end of i_list.

FIELD-symbols: <fs_table2> type standard table,

<fs_string> type c.

CREATE DATA v_dref Type table of (v_tabname).

assign v_dref->* TO <fs_table2>.

select * from (v_tabname) into table <fs_table2>.

assign <fs_table2> to <fs_string> CASTING. -

---

> error

i_list-i_tabledata = <fs_string>.

append i_list.

clear i_list.

Any thoughts?

Thanks again,

VG

PARAMETERS: p_tab TYPE tablename OBLIGATORY.

give a try

DATA: dref TYPE REF TO data.
Data: begin of i_list occurs 0,
i_tabledata(2550) type c,
end of i_list.
 
FIELD-SYMBOLS: <fs> TYPE any
 
CREATE DATA dref like line of  (p_tab). 
ASSIGN dref->* TO <fs>.
 
SELECT * FROM (p_tab) INTO <fs>  UP TO 10 ROWS.
IF sy-subrc = 0.
call method cl_abap_container_utilities=>fill_container_c
exporting
im_value = <fs>
importing
ex_container = itab.
exceptions
illegal_parameter_type = 1
others = 2. 
append itab.
endif.
endselect.

Hi,

My task is to download the data from a series of tables into the text file and then upload the same file into different set of same tables in a different name space. My code works fine when we are downloading and uploading all 'CHAR' data because I am reading into a string and using field symbols assigning the structure at the run time it inserts the data perfectly fine.

However if any table contains a field with decimal, currency, it throws an Unicode not convertible error rightly results in run time error. It is here I am facing the problem to downloading the data and uplaoding the data.

Uploading the data...

data: v_tabledata(2575) type c,

field-symbols: <fs_table> type any.

I read the data from the flat file into this string. From here, I need to upload into a table that has a decimal field...

I tried some thing like this...

assign v_tabledata to <fs_table>. (tried with standard table declaration too it did not work)

move <fs_table> to i_crword_temp. -

---

> runtime error...

modify (v_tabname) from i_crword_temp.

v_tabname is a database table

Hvae been trying few different things nothing seems to work.. Any thoughts or leads will be helpful.

Thanks in advance,

VG

As per your requirement, i developed this code snippet.

I download the data from ZTESTVBAK & upload the data to YTESTVBAK. Not sure why you're transferring the data to string & trying to read the string ?

Check this code snippet:

PARAMETERS: p_tab TYPE tabname OBLIGATORY DEFAULT 'ZTESTVBAK',
            p_dwld RADIOBUTTON GROUP grp1 DEFAULT 'X',
            p_upld RADIOBUTTON GROUP grp1.

DATA: dref TYPE REF TO data,
      v_tab TYPE tabname,
      lcx_sql_err TYPE REF TO cx_sy_sql_error,
      v_errtxt TYPE string.

FIELD-SYMBOLS: <itab> TYPE STANDARD TABLE,
               <wa> TYPE ANY.

CREATE DATA dref TYPE STANDARD TABLE OF (p_tab).
ASSIGN dref->* TO <itab>.

IF p_dwld = 'X'.
  SELECT * FROM (p_tab) INTO TABLE <itab> UP TO 100 ROWS.

Hi Suhas,

Thanks for the info. I had to read them into a string because I had to download the data and upload the same data into different tables in a different client under a different name space. I shall try this and definitely get back...

Thanks once again,

Hi Suhas,

the file donwloaded successfully, whreas during upload it gave an error with sy-subrc = 8. Bad data format. Any thoughts as to why?

Thanks,

VG
