Field symbols - casting error

[Former Member]

Hi,

I created a table dynamically and assigned it to field symbol. Now i want to write the contents of the internal table to a flat file in app server. Here is what i am doing.

parameters: p_table(30) type c default 'PA0008',

p_file LIKE RLGRAP-FILENAME default '/usr/sap/tmp/test.txt'. " Path to save files to

FIELD-SYMBOLS: <w_table> type standard table,

<w_wa> TYPE any,

<w_field> type any.

DATA: w_dyn_wa type ref to data,

w_dyn_table type ref to data.

CREATE DATA w_dyn_wa TYPE (p_table). "Suitable work area

ASSIGN w_dyn_wa->* TO <w_wa>.

create data w_dyn_table type standard table of (p_table).

assign w_dyn_table->* to <w_table>.

data w_dyn_data(5000) type c.

SELECT * FROM (p_table) INTO table <w_table> where endda >= sy-datum.

Data: w_temp type string.

OPEN DATASET p_file FOR OUTPUT IN TEXT MODE encoding default.

IF SY-SUBRC = 0.

loop at <w_table> into <w_wa>.

w_temp = ''.

do.

assign component sy-index of structure <w_wa> to <w_field>.

if sy-subrc <> 0.

exit.

endif.

concatenate w_temp <w_field> into w_temp respecting blanks.

if sy-index = 1.

transfer '' to p_file.

endif.

• transfer <w_field> to p_file no end of line.

enddo.

transfer w_temp to p_file no end of line.

write:/ w_temp.

endloop.

endif.

close dataset p_file.

when i run the program with PA0008 i am getting a casting error "Object not char like". How do i get rid of this error?. I tried moving the contents of field symbol to a string and appending it. It worked, but i lost the exact formatting of data in the file. In other words, it got rid of extra blanks. I need exact structure of internal table in the file.

Thanks,

Hi

Have u tried to use MOVE statament instead of CONCATENATE?

do.

assign component sy-index of structure <w_wa> to <w_field>.

if sy-subrc <> 0.

exit.

endif.

DESCRIBE FIELD <W_FIELD> LENGTH V_LEN.

MOVE <W_FIELD> TO w_temp+V_OFFSET(V_LEN).

V_OFFSERT = V_OFFSET + V_LEN.

It threw the same error "Objects not char like" at

DESCRIBE FIELD <W_FIELD> LENGTH V_LEN in byte mode.

I tried both byte mode and char mode.

[sridhar_k1]

I think your concatenate statement dumping when the program reaches the first non char like field in PA0008.

use DESCRIBE field <W_FIELD> type v_type, if it's not char like, move the field into a char field and concatenate or try to concatenate in byte mode.

Hi

Try to define w_temp as char instead of string

DATA W_TEMP(10000).
