How can I use the update operation in a VC Model

Hello experts,
i try to to use the update operation in my VC model.  I have developed an AS wich return a table. Now i want to update a table row. So I add the update operation to my model. But it doesn´t work. I mapped all attribute between the table and the update service. The event name is submit.
Another strange thing is: If i try to update in the service browser it cames the error message that the vandatory attribute ... is missing.
Any ideas??
Thanks
Marco

Hi Marco,
In this case it is possible that your update service requires a mandatory parameter which you are not providing.
When you drag your service onto the VC screen, right click on the service and test it.It will give you a clear picture of which parameters are required by the service and besides you can also use some test data to check if the service is working properly.
Do let me know if this helps.
Thanks,
Gaurav.

  • How can I use the update service

    Hello experts,
    could you please explain me how to use the update service from a business object in the VC. I have created a object which contains following attributes:
    - key(ID)
    - created by(UserID)
    - creted at(Datetime)
    - modifiedAt(Datetime)
    - modifiedBy(UsedID)
    - argument(string)                 Kardinalität: 1...1
    I have developed an application service which returns the whole entries of the table.
    Now I want to select the row and update the attribute argument.
    (For example the value is 24, and now I want to change it to 25. )
    But if I test the service UPDATE in the Service Browser it cames always the error message that a value in the mandatory field argument is missing.
    Any ideas?????? I am using the NWDS SP1.
    Many thanks!!!
    Regards Marco

    Hi Marco,
    In CAF you can do it by first using the update method to retrieve the BO instance and set the new value.

  • How can I use Office Update without the Office CD?

    How can I use Office Update without the Office CD? On the microsoft website I've clicked the options which mean I shouldn't need the CD (which wasn't supplied with the laptop), but poartway through updating the service pack I get a request for the Office 2000 Professional CD.
    Any suggestions?

    Hi
    Did you mean a Office or One Note?
    As far as I know the One Note is a part of the Recovering Image and the CD is not delivered with the unit. Furthermore the Toshiba units are not delivered with the Office 2000 software.
    Nevertheless, did you check the update function in the Help i.e. in Word?
    There you will find a options called Check for Updates

  • I have Elements 10 and a Nikon D7100. PSE10  CR 6.7 does not support the 7100 NEF. How can I get the updates to do this?

    I have Elements 10 and a Nikon D7100. PSE10  CR 6.7 does not support the 7100 NEF. How can I get the updates to do this?

    The D7100 requires camera raw 7.4 which is not compatible with Photoshop Elements 10.
    Your two main options are
    1) Buy a newer version of Photoshop Elements
    2) Use the Adobe DNG converter to convert the NEF files to DNG files which can then be used by Photoshop Elements 10.
    DNG  Converter 8.8

    i have 5gb of icloud storage, used 2.5gb but it wont let me unlock the other 2.5gb of storage. How can i use the remainig 2.5gb of storage?

    I got rid of AMDS, ASU ,QuickTime and iTunes from control ones I also found folder in Vista with D:\Users\Rick\Music\iTunes\Previous iTunes Library and there is one dated 2009-03012.itl. I moved this file up one folder and delted existing iTunes Library.itl. iTune still failed to identify my iPhone. There are other files iTunes Library Extras.itdb, iTunes Library Geniyes,itdn and iTunes Music Library,xml date dtd 06/18/2009 after upgrade except the latter which is date 06/23/2009. So something is not allowing me to pull or put everything back to when it worked.
    YES this is my only iPhone and only PC I have access to with iTunes.
    Here is what Apple gave to someone Sunday 28 June:
    http://discussions.apple.com/thread.jspa?threadID=2035950&start=75&tstart=0
    I checked these out too and they appear the same printed out nearly a week prior. I agree with Coach TO, if I had bad drivers or Vista errors it would not have shown up only when I updated to latest Version of 8.2.023. My Phone was identified on a PC with iTunes at the local AT&T store. He suggested I get phone into Recovery made while connected to iTunes and that resolves the problem 9 out of 10 time. Weak spot was he tried to get phone into Recovery without iTunes connection and thought I may have iPhone problem, then changed his mind when it worked while connected. He also stated it could take an hour. I have not tried to put my iPhone in Recovery lately, I think I did a while back and it failed to go into Recovery as error "iPhone detected by, not identified..."Has anyone tried forcing phone into Recovery? I understand you may lose all that is on phone. If iTunes still fails to identify would we not be in worse shape even if iTunes holds a recent backup which it does not for many of us? Will Apple take back or exchange phone if yours is not identitifed, AT&T today told me I had to go to Apple Store for this or anything to happen.

    I am not positive what you did is going to work, but it seems like you did the equivalent of imaging a small disk on a bigger disk. In that case, the first thing to do is update the partition table with fdisk. Start with fdisk -l in the vm for general information about the disk. Hopefully, the additional space will show. Then, work with fdisk to use the extra space. The easiest is to add a partition, then a file system on it. It is also possible to expand the last partition (you might have to delete it first), then expand what is on it (may be RAID, LVM, or the file system), layer by layer. As usual with fdisk, you run the risk of thrashing it all, so you may want to practice on a copy first. Obviously, the extra space can only be added to the last partition of the small disk.
    If the situation is more complex, you may have to boot a VM with both the small disk and the big disk at the same time. If you boot the VM off of an iso DVD image, you can then shell out, then run fdisk to partition the big disk the way you want, then use dd to copy the partitions you want in the order you want from the small disk. I am pretty sure not all combinations will work, but you get the idea. You can then take the small disk out, and boot off of the big disk.
    Come to think of it, you might just be better off with adding more space as a second virtual disk. You would then be free to partition/format it the way you want without messing with the first disk. Linux is so good with disk management, so many options.
    As a general statement, though, I like to put some distance between the high level file systems and the low level disk partitions, so I use LVM (Logical Volume Manager).
    Best of luck, keep us posted.

  • How can I use the print module to print different size images on one large "canvas"?

    How can I use the print module to print different size images on one large "canvas"? An example would be in Photoshop, go to file>new, and create the size paper I want, and move images of different sizes onto it.
    I was thinking the print module would do this automatically for me.

    You can't, at present. It's been a requested feature, so we'll see if it shows up in a future version, but it's not there at present.

  • I have an Apple MacBook Pro with 2 USB ports and a MiniDisplay Port. I also have an HDTV with a HDMI port. How can I use the TV as a display without any tethering wires between my computer and the TV?

    I have an Apple MacBook Pro with 2 USB ports and a MiniDisplay Port. I also have an HDTV with a HDMI port. How can I use the TV as a display without any tethering wires between my computer and the TV? I have a MiniDisplay Port to VGA adapter, but there are two issues with it: The new display doesn't have a VGA port, and even if it did, I wouldn't want to have my mac constantly attached to the display by a cable. I was looking for a way to use the TV as a display without any wires. Is there some type of bluetooth setup I could use? Please let me know if you have any suggestions.

    As I wrote above, I think you should look into the Apple TV yourself. The best place to find information about what it can and can't do and to ask your own specific questions is probably in the Apple TV forum, here:

  • How can I use the "Copy and paste" tool in order get stamps in the same position in different pages (Acrobat XI for PC)?

    With Acrobat 6.0 I was able to copy a stamp in the same position (I mean "exactly" the same one) of different pages just by using the "copy/past" tool.
    Now I am using Acrobat XI and it seems like it is not possible anymore: I am copying a stamp and I am trying to past it in anoter page, but it appears in the center of the page (or wherever it wants to...).
    Does anyone have a solution?
    Thanks in advance.

    Thank you very much. I'll be waiting for you message.

    I have two iphones, different telcos, i am using the same apple id for both - how can i use the 10GB icloud free memory of my new iphone 5?

    Thank you KiltedTim!
    YES, that is the free 5GB icloud memory for each apple ID. Can I not add the free 5Gb of my second Iphone to my original apple ID (5GB also) as I want to use one Apple ID name on both 2 Iphones? Is it necessary to have a different apple ID for the second Iphone to avail the free 5GB it carries with it?
