Opening files on Application server!!

Former Member — Thu, 14 Aug 2008 17:06:32 GMT

Hi all,

My requirement is I have 6 plants for which I have two internal tables in which data is coming from

a function module. Now here inside a loop at plant I want to open 6 files from one internal table and 6 from another table. Files are getting opened for both tables once and after its trying to open the same files due to which am getting an error.

Inside a perform :

*******************************************************************

inputfile-zprc = '\usr\sap\QAS\DVEBMGS00\work\ZJOHN.TXT'.

append inputfile.

inputfile-zprc = '\usr\sap\QAS\DVEBMGS00\work\test1.txt'.

append inputfile.

inputfile-zprc = '\usr\sap\QAS\DVEBMGS00\work\TEST.TXT'.

append inputfile.

append inputfile.

Try to use CLOSE DATASET also inside the loop at input file & endloop. In ur code there is no CLOSE DATASET. May be thats why u r getting error. Try it and see...

Hi Jerry,

Looking at the code I can see some problems:

1) You are not passing the file name to the open_dataset routine correctly. See Below for correction.

LOOP AT inputfile.

PERFORM OPEN_DATASET USING inputfile-zprc.

PERFORM PASS_FILE.

ENDLOOP.

*****************************************************************

LOOP AT outfile.

PERFORM OUT_DATASET USING outfile-zprc.

PERFORM OUT_FILE.

ENDLOOP.

ENDFORM. "OPEN_FILE

2) The datasets need to be closed. after reading the content.

Open Input Files

Read Input Files into Internal Tables or Process 1 record at a time building up output files in an internal table

Close Input Files

Open Output Files

Transfer data to output files

Close Output Files.

Hi , thanks for your help!!

Now I am not getting any error in openings files on application server but when I have to transfer the data that is fetched from database to app server files data is not getting transferred........

p1 = 2.

form conver_data using p1.

FIELD-SYMBOLS <ff>.

DO.

CASE p1.

WHEN 1.

ASSIGN COMPONENT sy-index OF STRUCTURE header_record TO <ff>.

WHEN 2.

ASSIGN COMPONENT sy-index OF STRUCTURE out_rec1 TO <ff>.

WHEN 3.

ASSIGN COMPONENT sy-index OF STRUCTURE itab_hts TO <ff>.

WHEN 4.

ASSIGN COMPONENT sy-index OF STRUCTURE header_record TO <ff>.

WHEN 5.

ASSIGN COMPONENT sy-index OF STRUCTURE out_rec2 TO <ff>.

WHEN 6.

ASSIGN COMPONENT sy-index OF STRUCTURE trailer_record TO <ff>.

ENDCASE.

***Break at internal table inside of itab_material table

IF sy-index EQ 9.

EXIT.

ENDIF.

IF sy-subrc <> 0.

EXIT.

ENDIF.

following needed if you need a field separator within the record
if sy-index > 1.
MOVE C_SEPARATOR TO W_WA+W_OFFSET(C_ONE).
w_rec_len = w_rec_len + c_one.
w_offset = w_offset + c_one.
endif.

DESCRIBE FIELD <ff> OUTPUT-LENGTH w_len.

w_rec_len = w_rec_len + w_len.

MOVE <ff> TO w_wa+w_offset(w_len).

w_offset = w_offset + w_len.

ENDDO.

endform

TRANSFER w_wa TO w_output_file1 LENGTH w_rec_len.

******************************************************************

TRANSFER w_wa TO w_output_file2 LENGTH w_rec_len.

TRANSFER w_wa TO w_output_file3 LENGTH w_rec_len.

TRANSFER w_wa TO w_output_file4 LENGTH w_rec_len.

TRANSFER w_wa TO w_output_file5 LENGTH w_rec_len.

TRANSFER w_wa TO w_output_file6 LENGTH w_rec_len.

Your help is appreciated

Thanks & Regards

Hi Jerry,

Personally I am not a big fan of using field-symbols in this way.

My preference would be as follows:

form conver_data using p1.

field-symbols: <fs> type any.

data: l_text(50) type c.

CASE p1.

WHEN 1.

ASSIGN COMPONENT sy-index OF STRUCTURE header_record TO <fs>

WHEN 2.

do 9 times.

ASSIGN COMPONENT sy-index OF STRUCTURE out_rec1 TO <fs>.

if sy-subrc eq 0. "Test if assignment worked

l_text = <fs>.

concatenate w_wa l_text into w_wa separated by c_separator.

endif.

enddo.

WHEN 3.

ASSIGN COMPONENT sy-index OF STRUCTURE itab_hts TO <fs>

WHEN 4.

ASSIGN COMPONENT sy-index OF STRUCTURE header_record TO <fs>

WHEN 5.

ASSIGN COMPONENT sy-index OF STRUCTURE out_rec2 TO <fs>

WHEN 6.

ASSIGN COMPONENT sy-index OF STRUCTURE trailer_record TO <fs>

ENDCASE.

endform.

Kind Regards

Hi, thanks for your answer!!!

As I said I have 6 company codes and for each company code the plant information should be transferred to outfile i.e 6 plants info should be transferred to 6 output files of app server.

LOOP AT S_COMPCODE.

outfile-zprc = '\usr\sap\QAS\DVEBMGS00\work\ZJOHN.TXT'.

append outfile.

outfile-zprc = '\usr\sap\QAS\DVEBMGS00\work\test1.txt'.

append outfile.

outfile-zprc = '\usr\sap\QAS\DVEBMGS00\work\TEST.TXT'.

append outfile.

outfile-zprc = '\usr\sap\QAS\DVEBMGS00\work\ZSAMPLE.TXT'.

append outfile.

outfile-zprc = '\usr\sap\QAS\DVEBMGS00\work\ZSAMPLE2.TXT'.

append outfile.

outfile-zprc = '\usr\sap\QAS\DVEBMGS00\work\ZSAMPLE1.TXT'.

append outfile.

CLEAR OUTFILE.

LOOP AT outfile.

PERFORM OUT_DATASET USING w_output_file.

PERFORM OUT_FILE.

ENDLOOP.

ENDFORM.
