Hi all,

We have upgraded our operating system to Windows Server 2003 and SAP system to 4.70. We use OPEN DATASET / TRANSFER / CLOSE DATASET statements to transfer data but after upgrade we get a lot of DATASET_CANT_CLOSE/OPEN errors. I guess this is something about the operating system but couldn't find a solution yet. Anyone had the same problem here? If so, I'd like to know how they solved the problem.

Thanks in advance;

    Hello Hakan

    You don't write from what operation system you upgrade, but anyway I have never work on a Windows Server 2003 platform.

    However I guess you have problems with permission settings.

    I could tell you about users/usergroups and read/write/execute permissions in UNIX, but I guess you can't use that in Windows environment.

    Best regards

    Hi Hakan,

    I noticed your post while searching for the cause of a similar issue I am experiencing...

    I'm not sure if anything was upgraded - but we are also suddenly getting issues with DATASET_CANT_CLOSE and they are only 80kb files...

    Just wondering if you managed to resolve your issues!

    Best regards,

    Hi there,

    I had the same problem under UNIX, and found the solution.

    I think its a bug in Release 4.6C (maybe in 4.70 too??).

    R/3 changes the folder- and filenames always to uppercase.

    so when You type in, for example, the path /tmp/test, R/3 changes them to /TMP/TEST.

    I made the /TMP/TEST (uppercase) folder on my machine and the problem was fixed...

    But I found the problem-detail described only in the ABAP-Shortdump...

    Hmmm... strange...

    regards Oliver

      We have been having the same DATASET_CANT_CLOSE problem for the past 1-2 years with a file size of several records (8 KB). And we know there is plenty of room on the server share.

      Our site used to be Windows NT SQL and never had a single problem. We migrated to IBM UNIX DB2 and now the problem is intermittent. Some days -- NO problems. Others days -- many problems.

      I have a batch job that runs every 15 minutes, which scrapes Work Orders from SAP and builds a flat file on a server share for TIMELINK to pick up. We can find no reason for the unpredictable problem. Sometimes a file is empty. At most, the file has 150 records, each with a length of 30 bytes.

      Anyone else experiencing the same problem? Any solutions?
