OPEN DATA SET to write files in application server folder - some of the files are missing

Hi,
I'm using OPEN DATASET statement in batch job to write the files in application server. what i'm experiencing is when i schedule the batch job all the files are not writing into the folder.
If i run the report again to write the missed files, the files are writing into the application server folder.
after opening the dataset, i'm closing it. do we need to give any delay between creation of the files? or until the first write operation is done, 2nd one can't start ..how can we achieve this.
Thanks for your help in advance.
Thanks,
Adi.

Hello Bathineni,
Are you using the sy-subrc check after the OPEN DATASET statement.
If not use a sy-subrc check and transfer the contents to file only when the OPEN DATASET returns value sy-subrc = 0.
if sy-subrc is 8 repeat the same loop say for 3 attempts until the OPEN DATASET becomes 0.
DO 3 TIMES. <---- put any number of attempts as you need
OPEN DATASET.
IF sy-subrc = 0.
TRANSFER contents to file.
EXIT.
ENDIF.
ENDDO.
CLOSE DATASET.
Regards,
Thanga

How come some of the apps are missing from the Adobe Application Manager.

When I downloaded the AAM for cloud it only gave 14 apps instead of the 26 apps to install. What do I need to do to see all of the apps? I have windows 7.
Thanks,

Branched this out to a new discussion. If you have programs missing it is likely that your computer does not meet the system requirements for that particular application. For example if you are running a 32-bit operating system you will not be given the option to install After Effects or Premiere Pro since they require a 64-bit OS.

Answer the following question regarding GUI_UPLOAD and Open Data Set

1. whats the connection or relationship of S_GUI to GUI_UPLOAD?
2. GUI_UPLOAD saves files to local directory of a use while OPEN DATA SET saves/archives files in the server directory. Where is the risk directed towards consuming disk space? Server disk or workstation disk space?
3. how will this work for multiple files?
4. Regarding Open Data Set - How the files will be put in AL11?

The GUI_DOWNLOAD only download the file to local PC...so any abap code running in other pc will not able to use the file.
BUt if you use open dataset to load the file APPLICATION server any ABAP pogram can access the file.
Following code explains how you load file using open data setto appl server,
you can check in t-code AL11 for files/dir in applicatin server.
you to change the value of myfile variable in my code..
you have to give the full path of the dirctory.

What is open data set and close data set

what is open data set and close data set,
how to use the files in sap directories ?

hi,
Open Dataset is used to read or write on to application server ... other than that i am not sure that there exists any way to do the same ... here is a short description for that
FILE HANDLING IN SAP
Introduction
Files on application server are sequential files.
Files on presentation server / workstation are local files.
A sequential file is also called a dataset.
Handling of Sequential file
Three steps are involved in sequential file handling
OPEN
PROCESS
CLOSE
Here processing of file can be READING a file or WRITING on to a file.
OPEN FILE
Before data can be processed, a file needs to be opened.
After processing file is closed.
Syntax:
OPEN DATASET <file name> FOR {OUTPUT/INPUT/APPENDING}
IN {TEXT/BINARY} MODE
This statement returns SY_SUBRC as 0 for successful opening of file or 8, if unsuccessful.
OUTPUT: Opens the file for writing. If the dataset already exists, this will place the cursor at the start of the dataset, the old contents get deleted at the end of the program or when the CLOSE DATASET is encountered.
INPUT: Opens a file for READ and places the cursor at the beginning of the file.
FOR APPENDING: Opens the file for writing and places the cursor at the end of file. If the file does not exist, it is generated.
BINARY MODE: The READ or TRANSFER will be character wise. Each time n characters are READ or transferred. The next READ or TRANSFER will start from the next character position and not on the next line.
IN TEXT MODE: The READ or TRANSFER will start at the beginning of a new line each time. If for READ, the destination is shorter than the source, it gets truncated. If destination is longer, then it is padded with spaces.
Defaults: If nothing is mentioned, then defaults are FOR INPUT and in BINARY MODE.
PROCESS FILE:
Processing a file involves READing the file or Writing on to file TRANSFER.
TRANSFER Statement
Syntax:
TRANSFER <field> TO <file name>.
<Field> can also be a field string / work area / DDIC structure.
Each transfer statement writes a statement to the dataset. In binary mode, it writes the length of the field to the dataset. In text mode, it writes one line to the dataset.
If the file is not already open, TRANSFER tries to OPEN file FOR OUTPUT (IN BINARY MODE) or using the last OPEN DATASET statement for this file.
IF FILE HANDLING, TRANSFER IS THE ONLY STATEMENT WHICH DOES NOT RETURN SY-SUBRC
READ Statement
Syntax:
READ DATASET <file name> INTO <field>.
<Field> can also be a field string / work area / DDIC structure.
Each READ will get one record from the dataset. In binary mode it reads the length of the field and in text mode it reads each line.
CLOSE FILE:
The program will close all sequential files, which are open at the end of the program. However, it is a good programming practice to explicitly close all the datasets that were opened.
Syntax:
CLOSE DATASET <file name>.
SY-SUBRC will be set to 0 or 8 depending on whether the CLOSE is successful or not.
DELETE FILE:
A dataset can be deleted.
Syntax:
DELETE DATASET <file name>.
SY-SUBRC will be set to 0 or 8 depending on whether the DELETE is successful or not.
Pseudo logic for processing the sequential files:
For reading:
Open dataset for input in a particular mode.
Start DO loop.
Read dataset into a field.
If READ is not successful.
Exit the loop.
Endif.
Do relevant processing for that record.
End the do loop.
Close the dataset.
For writing:
Open dataset for output / Appending in a particular mode.
Populate the field that is to be transferred.
TRANSFER the filed to a dataset.
Close the dataset.

Hi,
Due to serveral reasons
1. Check whether you have proper authority in the directory?
2. check the whether any files with same name?
3. use addition message in the open dataset statement so that you can know the system message it getting.
DATA: msg(100).
OPEN DATASET wa_BSEG_file FOR OUTPUT MESSAGE msg
IN TEXT MODE Encoding default.

Difference between SXPG_COMMAND_EXECUTE and Open data set mechanism

Can you please help me to know the difference between moving a file using FM "SXPG_COMMAND_EXECUTE" and moving file using "open data set - transfer file- close data set" mechanism?

Through 'SXPG_COMMAND_EXECUTE' u can execute a External command (ie.. UNIX /Windows/OS/400) In ABAP programming..
for Conversion Of Aplication server File/Move the file from one directory to Other...
The Command must be present in SM69.
Using this function module'SXPG_COMMAND_EXECUTE' , you can check the authorization of a user to execute a particular external command and run the command:
With the arguments specified in ADDITIONAL_PARAMETERS
On the target host system defined by OPERATINGSYSTEM and TARGETSYSTEM
If an SAP profile parameter is inserted in the portion of the command stored in the database, then the value of this parameter is substituted into the command. If an SAP application server is active on the target system (TARGETSYSTEM), then the profile parameter values are read from the profile that is active on that system. No parameter substitution is made in ADDITIONAL_PARAMETERS.
After substitution, the command is checked for the presence of "dangerous" characters such as the semicolon ( ; ) on UNIX systems.
If an additional "security function module" is specified in the command definition, this function module is also called in the course of processingebenfalls. This function module can prevent execution of the command.
If the authorization checks complete successfully, the command is run on the target host system.
Through Open Data Set u can read and write the file in the same directory...
Thnaks,
SD

Open data set problem with binary mode

Hi everyone,
I am trying to read into a buffer the content of a binary file (like Excel) and to write that content file using open data set into a folder destination.
The file destination has a size diferent than from the original one and cannot be open.
Here is the code.
DATA: lv_file_name(100),
         lt_content LIKE sdokcntbin OCCURS 0 WITH HEADER LINE.
MOVE '\computerTestA1.xls' TO lv_file_name.
OPEN DATASET lv_file_name FOR INPUT IN BINARY MODE.
IF sy-subrc NE 0.
    EXIT.
ENDIF.
DO.
    READ DATASET lv_file_name INTO lt_content-line.
    IF sy-subrc NE 0.
      EXIT.
    ENDIF.
    APPEND lt_content.
ENDDO.
CLOSE DATASET lv_file_name.
* DELETE DATASET lv_file_name.
CLEAR: lv_file_name.
MOVE '\computerTestB2.xls' TO lv_file_name.
OPEN DATASET lv_file_name FOR OUTPUT IN BINARY MODE.
IF sy-subrc NE 0.
    EXIT.
ENDIF.
LOOP AT lt_content.
    TRANSFER lt_content-line TO lv_file_name.
ENDLOOP.
CLOSE DATASET lv_file_name.
THanks in advance.

Hi,
I solve the problem.
In fact, when I try to write the last line of lt_content, it does write all the line even if this line is not full of data.
Solution :
DATA: lv_file_name(100),
         lt_content LIKE sdokcntbin OCCURS 0 WITH HEADER LINE,
         alen TYPE i,
         pos TYPE i.
MOVE '\mr0221TestA1.xls' TO lv_file_name.
OPEN DATASET lv_file_name FOR INPUT IN BINARY MODE.
IF sy-subrc NE 0.
    EXIT.
ENDIF.
SET DATASET lv_file_name POSITION END OF FILE.
GET DATASET lv_file_name POSITION pos.
SET DATASET lv_file_name POSITION 0.
DO.
    CLEAR lt_content.
    READ DATASET lv_file_name INTO lt_content-line ACTUAL LENGTH alen .
    IF sy-subrc NE 0.
      APPEND lt_content.
      EXIT.
    ENDIF.
    APPEND lt_content.
ENDDO.
CLOSE DATASET lv_file_name.
* DELETE DATASET lv_file_name.
CLEAR: lv_file_name.
MOVE '\mr0221TestB2.xls' TO lv_file_name.
OPEN DATASET lv_file_name FOR OUTPUT IN BINARY MODE.
IF sy-subrc NE 0.
    EXIT.
ENDIF.
LOOP AT lt_content.
    AT LAST.
      TRANSFER lt_content-line TO lv_file_name LENGTH alen.
      EXIT.
    ENDAT.
    TRANSFER lt_content-line TO lv_file_name.
ENDLOOP.
CLOSE DATASET lv_file_name.

Open data set from Text mode to Binary mode

Hello All,
In a program i am using the command
    OPEN DATASET file FOR OUTPUT IN TEXT MODE
    ENCODING NON-UNICODE IGNORING CONVERSION ERRORS.
Now i want to change this open data set to binary mode. I mean to change the command like below.
OPEN DATASET file FOR OUTPUT IN BINARY MODE.
when i do this. the output in the file is totally changing. I mean previously i have some text now i have some diffrent characters.
How can i use this command with out change in the output as previous output. Please tell me the changes and why i have to do.
OPEN DATASET file FOR OUTPUT IN BINARY MODE.
Regards,
Lisa.

        Lisa Roy

Text Mode means that the records in the file have a carriage return marking the end of each record.
Binary Mode means the file is a string of data.
You can't read a text file in BINARY MODE, or a binary file in TEXT MODE.
If you are changing the mode, then you must be supplied with a file in the new mode.
