Open dataset filename length.

Hi all,
Could any one help me regarding opendataset.
i am creating files on app server using open dataset.
for one program the code i have written is working.
and for another the file is not getting created.
my doubt is is ther any restriction with file name length while using open dataset.
regards,
Murali.

Hi Murali,
There is no such restriction on file length ...but you may not be able to view the contents in one line ...but on downloading the data on to presentation layer via CG3Y you can view the entire record ...

OPEN DATASET FILENAME FOR OUTPUT.

HI,
While doing unicode enable inECC6.0 FOLLOWING ERROR IS COMING.hOW IT WILL BE RESOLVED.
oPEN DATASET physname FOR OUTPUT.

Hello,
For opendataset u need to add the below coding.
open dataset 'filename' for output in text mode encoding default. ( Based on ur filetype)
binary mode encoding default
if it not a unicode system then non unicoding must be added.
N.B
In the Transfer stmt the data types apart from CNDT will result dump.
So please ensure that all are of CNDT types.

Open dataset file length

Hi Friends,
I am uploading a file into SAP server and I would like to upload with 300 length char. ( I mean The file should contian 300 coloms)
where we can declare the length of the file?
Thanks,
Sridhar

Hi Sridhar,
Define variable of type string or type CHAR(XXX), XXX should be equal or more than expected length of record.
Open dataset in text mode or binary mode.(prefer binary mode - if user will go to OS and see the file by double click prefer text mode so that it will get downloaded in readable format).
if dataset is opened successfully -
Loop at your internal table into string or defined variable .
Use transfer command to transfer each line.
Close the dataset.
Here goes some code:
DATA: lv_file1 TYPE string.
FIELD-SYMBOLS: <f_t_table> TYPE ANY.
lv_file1 = lfile_path.
IF im_binary_mode IS NOT INITIAL.
    OPEN DATASET lv_file1 FOR OUTPUT IN BINARY MODE.
ELSE.
    OPEN DATASET lv_file1 FOR OUTPUT IN TEXT MODE ENCODING DEFAULT .
ENDIF.
IF sy-subrc EQ 0.
    LOOP AT t_table ASSIGNING <f_t_table> .
      TRANSFER <f_t_table> TO lv_file1.
    ENDLOOP.
    CLOSE DATASET lv_file1.
   MESSAGE s027(zdev) RAISING download_success.
ELSE.
    MESSAGE e028(zdev) RAISING download_error.
ENDIF.
Now important thing:
Record with length more than 255 gets downloaded successfuly intext mode but when you try to read it via AL11, CG3Y, or with OPEN dataset- READ- write ..CLOSE dataset you can see only 255 character.
Dont worry about this.
AL11 and CG3Y is unable to display more than 255 char in text mode. if you are writing content of the file on list screen, use OFFSET, like WRITE: /01(500) lv_string.
write statement in AL11/cg3y doesnt have this offset in write so more than 255 length cant be seen.
I hope u get the answer and able to understand this solution.
Bless u.

Open dataset filename for output in text mode encoding default

Hi,
When I excute this command I get a sy-subrc = 0, but no file is created. This happens in an ECC 6.0 system. In 4.6C works ok.
filename has the following structure '
server\directory\filename'
What am I doing wrong??
Thank you very much for your your help.
Regards.

Hi,
Can u tell what syntax u have written for open statement.
In programs with active Unicode check, you must specify the access type (such as ... FOR INPUT, ... FOR OUTPUT, and so on) and the mode (such as ... IN TEXT MODE, ... IN BINARY MODE, and so on). If the file is opened using ... IN TEXT MODE, you must still use the addition ... ENCODING. If the Unicode check is enabled, it is possible to use file names containing blanks.

OPEN DATASET code

Hi all,
I have the following code to output data.
OPEN DATASET FILENAME FOR OUTPUT IN TEXT MODE encoding default.
my question is what the format of output file should be? Is there any specific requirement? And if I run this code successfully, I should save the file onto server. How can I see the file? Thanks in advance!
Linda

u need to declare an internal table which contains all fields of type c and length as correspodning to itab fields.
loop at itab.
tab-field1 = itab-field1.
tab-field2 = itab-field2...and so...on
append tab.
endloop.
so, tab will be having data which is in character format.
now, this internal table can be used to download to application server using datasets.

Thanks Sri for your help. I tried to apply the logic, but the error i am getting here is -

Err with scheduling an abap program using open dataset

issue: have an abap program which uses "open dataset ... for input ..." to read the file.
- with manual ly running it, receive the following message "dataset_not_open".
- with scheduling it, receive same message
attempting to run an abap program as part of a process chain (ie scheduling a background job) in BI.
the abap performs the following fxns:
1) read a file on the server
2) removes delimiter, renames it
3) rewrites the file onto the server
initially used ws_upload for reading and ws_download for writing the file.
- both fxns worked fine if it is run manually --> but failed as a background (part of process chain)
- note 7925 states can't use ws_upload, download for background jobs
-so switched to "open dataset"
Any suggestions as to why the "open dataset" does not work is greatly appreciated it.
B.A.

Thank you for all responses. here is more info about the err message:
sy-subrc = 8
'invalid argument'
I looked up the invalid argument in note 99155 --> due to "The destination file is no longer available during repeated file access. "   So, the following steps were taken:
- file was regenerated and
- file was placed on the server to be read
have the following code:
OPEN DATASET FILENAME FOR OUTPUT IN TEXT MODE encoding default
                      MESSAGE D_MSG_TEXT.
also have tried the following:
   OPEN DATASET d1 for input in text mode encoding default.
   open dataset d1 for output in text mode encoding NON-UNICODE..
   open dataset d1 for output in text mode encoding utf-8.
none had worked. system --> status shows no unicode.
THanks again for any suggestions.

Open Dataset fails with "Invalid Argument"

From an ABAP program I can't write to a share folder on a windows 2000 box. The share permissions are set to Everyone Full control. I can write to a share on a windows 2003 box, but not windows 2000. Here is my code:

I noticed that the kernel has the following info:

I was thinking there was a problem writing to a win 2000 box with an SAP Unicode Kernel.
Anyone have a clue?
Thank you,

hi
the shared folder must be accessible to the os user of your R3 installation. bcoz when u run the pgm this user will be used at the os level.
for checking this logon to the R3 os and try to access the share path. it should be accessible without providing any logon credentials.

Truncated record in OPEN DATASET ENCODING NON-UNICODE

Hi,
I have to read a Unicode created file into a non-unicode SAP System, version 4.7.
When I make the OPEN DATASET using ENCODING UTF-8 y get a CONVT_CODEPAGE dump. That´s odd cause my system is non-unicode. I don´t wanna use IGNORING CONVERSION ERRORS attribute, the output will be corrupt.
But when I use ENCODING NON-UNICODE or ENCODING DEFAULT the READ DATASET mysteriously truncate the record which try to read from real 401 characters to 361 characters. Variable is string.
I can see full records through AL11.
Any ideas?
Thanks,
Pablo.

Hi,
Try using:
open dataset filename in text mode encoding default for input
ignoring conversion errors.
As said in AL11 its coming so the above code is used for that.
Hope this will surely help you !!!

Problem in open dataset

Hi Friends
Earlier I used FTP option for picking and transferring files, now Instaed of FTP I am going with application server concept.
while receving, there is no problem between two types.But while transfrring the XML file from SAP to application server it generated some error, the format is not correect like that.But if I pass the same value in foreground its working fine.
here I am attaching the coding for application server and foreground method
open dataset filename for output in binary mode.
*open dataset filename for output in TEXT MODE Encoding UTF-8.
loop at it_xml.
transfer it_xml to filename.
endloop.
close dataset filename.

I dont know how to convert this binary file into xml format in Application server concept.
please help me to resolve this.
Thanks

HI,
    YOu can use CALL TRANSFORMATION for converting into XML format .
CALL TRANSFORMATION id SOURCE root = lt_TABLE
            RESULT XML it_xml.
Then call DATASET

Open dataset statement in different SAP versions

Hi ,
I have to write a program which is for extracting data from application server. I have to run this program on different sap versions like, 4.6b, 4.6c, 4.7, 5.0 . I am using 'OPEN DATASET' statement in my program. But the problem is, in versions below 4.6c, this statement is written as "OPEN DATASET filename FOR READING IN TEXT MODE".
And in versions above 4.7 it is written as "OPEN DATASET filename FOR READING IN TEXT MODE DEFAULT ENCODING".
So when this statement will be executed in versions below 4.6c, it will give syntax errors.
Can you let me know how to solve this problem.
Thanks.

Hi,
differ btw. syst-SAPRL
-> if you get syntax-error create a subroutine-pool
with abap command generate subroutine...

Maximum length of field in OPEN DATASET

Hello,
I try to import a file from server (for test purposes downloaded on the server directory with transaction CG3Z in ASC) with an unknown length of lines.
Here is my coding for the import into ABAP:
OPEN DATASET p_pa_snam FOR INPUT IN TEXT MODE .
IF sy-subrc NE 0.
ELSE.
    DO.
      READ DATASET p_pa_snam INTO g_file.
      IF sy-subrc NE 0.
        EXIT.
      ENDIF.
      IF NOT g_file IS INITIAL.
        SPLIT g_file AT p_pa_sep INTO
          wa_textfile_a-textid
          wa_textfile_a-langu
          wa_textfile_a-textname
          wa_textfile_a-textobj
          wa_textfile_a-text.
        APPEND wa_textfile_a TO zs_textfile_a.
        CLEAR wa_textfile_a.
      ENDIF.
    ENDDO.
So you see that I move the lines from the file to g_file which is of type STRING.
In the import wa_textfile_a the field text is of type STRING too to receive the rest after splitting at the separator into the other fields.
I would expect that this element g_file is a long one which could store my lines from the loaded file,
which could have possibly a length of 5000 digits and more.
Currently I stuck in this step with a length of 217 (!!!) digits in g_file, when importing longer lines (in test I had a line of more than 600 digits.
Is there any idea, what is wrong here or can anyone from you tell me about limitations?
Your help is really appreciated!
Best regards
Dirk

Hello Micky,
you are right!
I checked it by using CG3Y!
Ok, so we will move the file to the server via another solution!
Oh, in my thread above there is a mistyping, 257 instead of 217!
The last digit maybe is from wrong counting! But I won´t count that again!
Best regards
Dirk

In OPEN DATASET Statement Filenames are platform-specific How to specify MS

In OPEN DATASET Statement
Filenames are platform-specific. You must therefore use file- and pathnames that conform to the rules of the operating system under which your R/3 System is running. However, you can also use logical filenames to ensure that your programs are not operating system-specific. For further information, refer to Using Platform-Independent Filenames.
DATA FNAME(60).
FNAME = '/tmp/myfile'.
OPEN DATASET 'myfile'.
OPEN DATASET FNAME.
This example works as long as your R/3 System is running under UNIX. The program opens the file "myfile" in the directory in which the R/3 System is running, and also opens the file "myfile" in directory "/tmp".
FNAME = '[TMP]myfile.BIN'
OPEN DATASET 'myfile.BIN'.

Just get the input file name from the application server through selection screen and keep it in parameter(p_inpfile).
Then pass the parameter to OPEN DATASET statement.
