Unable to check flight availability in DEMO 3.0

Anybody,
I finished configuring the demo but when I execute I get the following error:
Unable to check flight availability.
Error Type: XI system error
Error Details: An error occurred when determining the business system (LD_ERROR)
Looking at the logs I found the following exception (actually more than one)

It appears I don't have permission to execute load the bean and execute it. Can anyone tell me what role or authorizations I need to assign to my XISUPER user in order to do this...
Thanks
Diego

Alessandro, I'm experiencing almost the same kind of error as described before. However, in my case trx SLDCHECK (executed from the XI server and from the SAP application system) also generates errors. The error Im getting is as follows:
Testing SLD API
An exception has ocurred
Description: Exception in SLD Client: AbapaSLDRequestHandler.ping() server connection *** failed ***
Summary: Connection to SLD does not work
=> Check SLD function and configurations
I have to say that the SLD home page from Integration Builder works correctly and when SLDCHECK is executed the browser opens the correct url and loads the page.
I have followed all congiguration steps (maintain SLD details with trx SLDAPICUST, maintain HTTP and TCP/IP destinations, activate XI services, etc..) mentioned in the SAP documentation, however the problem persists.
Thanks in adavnce for any feedback!
Thanks, Roberto

"Unable to check for available downloads" since upgrade to 8.1

It appears a number of people are having this problem but are all under different headings...
I can purchases new music/items and have them download right away, but it appears anything that was waiting for me to download prior to the upgrade to 8.1 is stuck somewhere. When checking for Downloads (no matter which way you do it) I get an error that says "Unable to check for available downloads. The iTunes store is temporarily unavailable."
Troubleshooting guides suggest ensuring your firewall is allowing all permissions appropriately... I even turned them to "ask for permission" so that I would know it was trying. No luck.
When is Apple going to recognize there's a problem? If I can purchase new items and get them to download right away, clearly there is no issue with ISP or Firewall.

Having the same issue. I even downloaded a rental last night to have it disappear this morning and it says I have purchased the rental but never downloaded it. I have played with all network settings include as open as possible and no luck.

Unable to check for available downloads... Try again later.

"Unable to check for available downloads. The iTunes Store is temporarily available. Please try again later." Forever, really.
It all started when I attempted to "Download All Updates" (104 of them) and it crashed. Now it tells me that I've already purchased the items, and to "Check for Available Downloads", which throws the above error for going on three days now. Email support has not answered my inquiry / report.
In the meantime, the "Genius Folks" in the Apple Store inspired me to a partial workaround, at least to whittle down the queue. By installing the apps to my device, updating them there, and syncing them back to iTunes. But I still have a few stuck in some weird state, that iTunes is unprepared to process.
BTW, the geniuses never heard of this problem, even after I showed them that a quick Google search came right back with 404,000 hits. I've seen iTunes unable to connect to the Store when there were too many updates, for years, on both Windows and OSX, and many released versions, but I've always been able to download them individually, instead of in bulk. First time it crashed and left me hosed.
Seems like a server-side issue. Any suggestions on how to get through to the powers that be, and have my queue cleaned up? And maybe get the attention of the Q/A and development departments to actually acknowledge and fix a long standing and most inconvenient bug?

Thank you so much - I have spent the last 4 days scouring internet forums trying to solve this problem (I couldn't connect to the iTunes store/download any apps or updates) and just as I was about to give up I stumbled across your post. I can't believe I've had such big problems all because of the ampersand in my billing address! How did you discover this?! It's such a small detail! To my huge relief it's all sorted now and I can now update my apps and download again! I'll be cancelling my appointment at the genius bar tomorrow too! Thanks again very much!

Unable to check for available downloads.

I've been getting the message, "Unable to check for available downloads. The iTunes Store is temporarily unavailable. Please try again later." all September long and I'm not sure how to fix it.
I've been told by iTunes support that it should be up within 24 hours but it's been over 500 hours so far.
I've been told maybe my iTunes is out of date but I have the most recent.
I've also been told it's my ISP/ net connection but I have no problems downloading some things.
I have had 40 items unable to be downloaded for a while and that annoyed me but tonight I tried downloading 5 more songs and then I had to accept a new 'Terms of Service' so I did and then those 5 ended up with the 5 others in some kind of file purgatory.
Not sure how much this could help but iTunes Support doesn't seem to care and they just told me to ask here instead of them.

And how do you check each pending download? My download screen has absolutely nothing on it. At the bottom of it there is "16 iTunes Downloads Available." I click on the download button next to it and get the same error: "Unable to check for available downloads. The iTunes Store is temporarily unavailable. Please try again later." Help, I just bought an app I'm dying to play on my iPod!

Unable to check for available downloads. the network connection was lost

in my downloads window in iTunes it shows i have "28 iTunes downloads available". when i try to download them, i get the error "Unable to check for available downloads. the network connection was lost."
my connection is fine though, as i can individually download purchases by clicking on the cloud icon.

I followed the advice on Holgr's link, i used screen flow to capture the error message, and then made the video available to apple support. My issue was immediately escalated, and my account started working again shortly after.
I received no additional messages from tech support, i had no idea the problem was resolved until i tried it again.

Unable to check for available downloads. The network connection timed out.

I downloaded iTunes 10.1.2 last week, and attempted to upgrade some music to iTunes Plus. I'm showing 35 items in my download queue, but when I attempt to download I get a message "Unable to check for available downloads. Network connection timed out."
I e-mailed Apple Tech Support multiple times, and received their standard list of links for things to try. So far I have reinstalled iTunes, turned off my Norton Firewall, checked the program rules settings, flushed the dns cache, and unchecked the "allow simultaneous downloads" box. Still no luck.
Apple's last e-mail requested I send them my account info so they could reset my password, and check my system. I'm still waiting for that to happen.
I'd appreciate any user suggestions for this problem.

Fundamentally it is an apple itunes server issue - if you have a lot of downloads the "check for downloads" request can take longer than the default windows internet connection timeout setting - which is 30 seconds on more recent versions of windows.
You can work around it though - without requiring apple to "segment" your download list, by adding a windows registry setting.
Apple re-enabled my downloads after I was burgled and then I was stuck - my "check for downloads" was always timing out - and the support guy had no clue - so I went digging, and found a a microsoft article here http://support.microsoft.com/kb/181050 which tells you how to change change that default timout value by adding a registry setting. Besides adding the ReceiveTimeout setting detailed on that page - I also changed the KeepAliveTimeout - just in case.
HKEYCURRENTUSER\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ReceiveTimeout
which I set to 180000 milliseconds (3 mins)
HKEYCURRENTUSER\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\KeepAliveTimeout
which I set to 181000 milliseconds (3 mins and 1 second)
Use regedit to make the change - both settings are DWORDS with decimal values. You'll need to restart your PC to apply the change.
After the change and restart and one initial failed attempt the request for downloads worked - when the apple itunes server responded after 2 minutes !!

Can't download purchased content. "Unable to check for available downloads"

I can no longer download purchased content. Each time I check for available downloads I get an error message that says "Unable to check for available downloads. The iTunes Store is temporarily unavailable. Please try again later."
The screen says I have 17 itunes downloads available but cannot download them. The most recent purchase I am not able to download is Season 3 of Dexter in standard def and some other season passes. This is really annoying; I already paid for the content and am not able to watch it...

After sending two e-mails and recording a screen-cast video solved the problem.

Unable to check for available downloads. An unknown error has occurred. (-50)

When I click on a station, it pauses for a few seconds and then gives the error message "Unable to check for available downloads. An unknown error has occurred. (-50)". I wanted to check on other solutions before I uninstall.

Hi, remainingahab.
Thank you for visiting Apple Support Communities.
Here is an article that I would recommend going through when experiencing error -50.

Unable to check for available downloads. A duplicate filename was specified.

I cannot access my downloads, or rather "download" them, because of the - Unable to check for available downloads. A duplicate filename was specified. - keeps coming up.

Did you resolve this issue? I am having the same problem and CANNOT figure out what to do. It is driving me crazy!

Unable to check for available downloads - Can't download my purchases

I've already 50 files in queue. Some of those files are 8 months old. And recently I purchased a song (the free ones).
And it said 'Checking for downloads' and then it started giving me this error "Unable to check for available downloads."
I tried to 'Report a problem.' But I can't report to apple either. Whenever I try to do so, I'm taken to http://www.apple.com/support/itunes/#itunescards_andcodes rather than this address http://www.apple.com/support/itunes/store/songcode/
And the new page has no form to fill up! I just can't do anything. Please help me!
PS - I recently updated from iTunes 10 to 10.1.

Unable to check for available downloads. The network connecting was lost.

I have purchased a film on my Apple TV and now want to download it to my iTunes on my MacBook. I can see that I have 1 available download, but when i try to down load it, it just keeps saying:
"Unable to check for available downloads. The networl connection was lost"
I know there is not a problem if my network!
is anyone else having the same problem? Is this a problem with iTunes or my MacBook?
cheers

Hello loz114,
This is frequently due to an inability to establish or maintain a connection to the iTunes Store. The following article provides some useful information and troubleshooting steps that can help restore this connection.

"Unable to check for available downloads" message - counted download items

I've been trying to download touch upgrade since Wednesday after buying it (shows on account). I am showing that I have 26 downloads. When I repeat trying to upgrade process or attempt downloading the 26 downloads on the download page (bottom, down arrow), I repeated get this message: “Unable to check for available downloads. The iTunes store is temporarily unavailable. Please try again later.”
I have reinstalled iTunes (downloaded current version, which I already had), I have deauthorized and then re-authorized my computer, I have cold booted, I have turned of firewall and virus (McAfee). Since I started trying to upgrade, I have purchased a song; it certainly has no trouble finding iTunes available for that purchse! I have run the iTunes diagnostic, and everything passed. I have done everything I know to do except give up.
Help!?

I'm trying to download songs that was transferred via Carbonite, not getting message that states "Unable to check for available downloads, iTunes is temporally unavailable"

I'm trying to download songs that was transferred via Carbonite, not getting message that states "Unable to check for available downloads, iTunes is temporally unavailable". What do I do? Any suggestions??

Same problem, I have a season pass for Mad Men and suddenly cannot download, says iTunes is temporarily unavailable. Problem occurred before I updated to the new iTunes and afterwards, on two different computers. Here is what Apple had to say:
"I have verified that the iTunes Store is functioning and accepting connections, which indicates that the issue is related to your internet connection, local network, or your local computer itself. This article outlines some of the likely culprits:

You may find another user with the same operating system or ISP that may be able to help resolve this issue. You can find the iTunes discussions group at:

If you are still unable to connect to the iTunes Store or receive this error, you will need to call our AppleCare technical support team.

so far, no luck.
