Janet - Might be worth it to check the permissions/owner on the directory. You might be able to use function module SUBST_GET_FILE_LIST and trans SE37 to do this.

Keep in mind that the authority check only verifies your authorization level --> it doesn't verify that the drive/path/filename is valid. Also, it looks as if you're attempting to write to a network drive (assumed because of the back-slashes "
"). If you're writing to a Unix directory, use forward slashes '/'.

Error opening dataset, return code:        8

Hi,
I'm passing the information from a txt to a transparente table. The problem is that it throws me the following message: Error opening dataset, return code:        8 .
When I debug it the first row of information enters to the internal table but after it this erro comes.
The code is the following:

Open dataset - return code 8 - msg - Permission Denied

This is the first time this company has tried to write files to the application server. They are running under Windows. The network admin set up a folder and I am getting a return code of 8 on 'open dataset'. When I use this function to get more information I am getting
a run-time error that the ABAP is bad.
What is wrong with this function call?

Return code 8 on OPEN DATASET

Hi All,
i try to migrate a file with ISU-Migration workbench.
in the Display option I can see the file. All looks fine.
When I press IMPORT I got the message "migration executed" but actually it did not read anysthing. So I debugged and came to the OPEN DATASET.
There I get a sy-subrc of 8.
Do not remember what this means...probably the directory is protected or something...
Who knows?
Thanks in advance
Thomas

hi Thomas,
     hi thomas u can do authority check as stated below..
if sy-subrc is 8 it means too many parameters (fields, values). Maximum allowed is 10. I have also added the other sy-subrc condition so that u can benifit...
     AUTHORITY-CHECK OBJECT object
    ID name1 FIELD f1
    ID name2 FIELD f2
    ID name10 FIELD f10.
object
Field which contains the name of the object for which the authorization is to be checked.
name1 ...
Fields which contain the names of the
name10
authorization fields defined in the object.
f1 ...
Fields which contain the values for which the
f10
authorization is to be checked.
AUTHORITY-CHECK checks for one object whether the user has an authorization that contains all values of f (see SAP authorization concept).
You must specify all authorizations for an object and a also a value for each ID (or DUMMY).
The system checks the values for the IDs by AND-ing them together, i.e. all values must be part of an authorization assigned to the user.
If a user has several authorizations for an object, the values are OR-ed together. This means that if the CHECK finds all the specified values in one authorization, the user can proceed. Only if none of the authorizations for a user contains all the required values is the user rejected.
If the return code value in SY-SUBRC is 0, the user has the required authorization and may continue.
The return code value changes according to the different error scenarios. The return code values have the following meaning:
4
User has no authorization in the SAP System for such an action. If necessary, change the user master record.
8
Too many parameters (fields, values). Maximum allowed is 10.
12
Specified object not maintained in the user master record.
16
No profile entered in the user master record.
24
The field names of the check call do not match those of an authorization. Either the authorization or the call is incorrect.
28
Incorrect structure for user master record.
32
Incorrect structure for user master record.
36
Incorrect structure for user master record.
hope i had answered u.. rewward if u find it useful.

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.

'Open Dataset' command - add ASCII code in a unicode system

Hi,
I use following comand in order to save a file on an application server.
open dataset <path> for output in text mode encoding default.
Is it possible to convert file to ASCII code instead of the system setting unicode and to ignore conversion errors? If yes, please tell me how.
Thanks!

problem exporting text in hebrew
Similar kind of problem has been solved here.. check that link first
Use the class CL_ABAP_CONV_OUT_CE and use it to convert file from unicode to ascii.

SY - System fields and return codes in ABAP

Hi
I'm new to ABAP, where do I find what the meaning of the system field return codes are ?
example SY-SUBRC returns a number of codes 0, 2, 4, 8 etc what do they mean.
Is there a resource somewhere that provides this information for all the system fields.
I have searched high and low and have found little, they must be defined somwhere ?
cheers Hugh

Here is a listing of all of the system fields.
http://help.sap.com/saphelp_scm50/helpdata/en/7b/fb96c8882811d295a90000e8353423/frameset.htm
As for what the return codes( 0, 4, 8) for SY-SUBRC mean, that is a little tricky. The meanings of the values are dependent on what statement was used previously. They would mean different things when used with different statements. For example, if you check SY-SUBRC after a FIND statement, the return code value 4, would mean something different than if you had check the SY-SUBRC value after doing an OPEN DATASET. So you need to look at the specific statements in help.sap.com and see what it says about the SY-SUBRC values for each statement.

Hello experts!
I am facing a peculiar problem with ABAP keyword OPEN DATASET.
I have a directory to which I am adding new files using OPEN DATASET FOR OUTPUT.. this works perfectly fine in the Consolidation system. But the same thing does'nt work in the Production system! It return SY-SUBRC = 8
After reading several other posts on SDN and other forums, the following causes were touted.
1) Path incorrect
2) No Authorization
But upon checking, neither of the wo are possible because the path is maintained properly and the authorizations at OS level are given (R/W) to this folder. Moreover, the user has S_DATASET auth object!!
Then I read somewhere else that having multiple Application Servers could be a possible cause and that running the code as a background job would be afix.. Is it so?
Even if it is, the application is in ABAP Web Dynpro and is launched from the portal.. hence launching it as a background job is not an option... Any solutions?????
Any help on this would be appreciated...
Thanks in advance, Amith

Hi,
Yes this is true that if we are having the multiple application server then this kind of error occures if your specified directory is not mapped on the alll the avaiable sAP application servers.
I guess when ever you are running your application then system will pick the appkication server based on the present load. Hence if your directory is not mapped in that application server then you wil get this kind of issues,
so i guess check with you basis team that spctified path is avaiable in all the application server.

File not found in shared folder when transferred through Open Dataset

Dear Experts,
I am transferring a file to a shared folder using open dataset .
The sy-subrc value returns as 0 . But i am not able to find the file in the destined path.
But when i try to retrieve the file from the same path through CG3Y to my local PC , i am able to retrieve the file.
Could you please throw some light into this as to why this is happening.

Hi venkat,
Sorry for the delayed response . The Authority check FM also returns the sy-subrc value 0 .
But still not able to find the File . I am Trying to paste the data through FTP_R3_To_SERVER . But it is not supporting Non-English Characters. Is there any way to paste the file through FTP ( with Non English Characters ).
{code}
call function 'FTP_CONNECT'
   exporting
     user            = user
     password        = pwd
     host            = host
     rfc_destination = dest
   importing
     handle          = hdl.
if sy-subrc = 0.
   CALL FUNCTION 'FTP_R3_TO_SERVER'
     EXPORTING
       handle               = hdl
       fname                = FNAME
*      BLOB_LENGTH          =
      character_mode       = 'X'
TABLES
* BLOB                 =
      text                 = it_data1
    EXCEPTIONS
      tcpip_error          = 1
      command_error        = 2
      data_error           = 3
      OTHERS               = 4.
endif.
{code}

Open dataset (UNICODE) for english en polish characters

Hi,
I have a problem on my multi language project on where I need to manage English language and polish language.
I have a table (that we can call TABLE) I manage the translation on it. When I am connected in English I can see some squares instead some polishes characters. When I am connected in polish, I have the right characters. Any way I don’t think it’s a problem, cause if I copy/paste the square on Word, I find back the corrects characters.
My problem is after.
I have a structure with the collon name and an internal table with data.
I use the module function DDIF_TABL_GET on my table TABLE to have the collon name corresponding to the language wanted.
I am building a string with that and some carry return.
(Here in English I have again some square, but always the good character if I paste it on Words.)
Now I would like to put this string in a file using the good encoding.
I have tried lot of ‘opening dataset’ and lot of ‘encoding’.
I have a file on SAP (transaction FILE)
(Here in English I have again some square, but always the good character if I paste it on Words.)
If I download this file on my computer, I have wrong characters.
Could I have help?
My wrong code:
OPEN DATASET lv_filename FOR OUTPUT IN TEXT MODE ENCODING UTF-8.
TRANSFER u_contenu TO lv_filename.
CLOSE DATASET lv_filename.

Hi,
Use this
OPEN DATASET File_path FOR OUTPUT IN TEXT MODE ENCODING NON-UNICODE
WITH SMART LINEFEED
it will definitely work.

Open dataset for input don't work after upgrade from 46C to 47

We did an upgrade from 46C to 47, after that all the Z programs that have the sentence "open dataset for input" alwas send a sy-subrc = 8, the curios things is that the sentece "open dataset for output" works ok.
Please I need help to solve this?
En example of code.
PARAMETERS: P_ARCHF(60) OBLIGATORY DEFAULT
'C:\20050900.txt' LOWER CASE.
OPEN DATASET P_ARCHF FOR INPUT IN TEXT MODE.
IF SY-SUBRC <> 0. MESSAGE i001 WITH ARCHIVO. stop. endif.

Well, it's telling you that the datset doesn't exist. From the help in 4.7:
OPEN DATASET
Addition 1a
... FOR INPUT
Effect
OPEN ... FOR INPUT opens the file in read mode.
If the file does not exist, OPEN ... FOR INPUT fails with Return Code SY-SUBRC = 8.
Note
If OPEN DATASET is not executed in a Unicode program and if the user has write authorization for the file, the file is opened in read and write mode. Otherwise, it is only opened in read mode.
