~messageline.dim always 1, even when more than 1 message generated in ABAP

Can anyone help explain how the ITS ~messageline gets populated. In my transaction I am creating a number of warning messages. However, the ITS is only displaying 1 each time.
I am using the following code, but ~messageline.dim is always 1.
`repeat with m from 1 to messageline.dim` `messageline[m]``end`
Thank you
Karen

G'day Karen,
I had a similar problem with my ALV in the ITS template.
My solution was that I had added too many Service Parameters to my service in transaction SICF.
The only parameters I have for my service are:
~TRANSACTION (my transaction code)
~THEME 99
With only those parameters against my service, everything started to work, having more than 1 entry show up in my ALV and the scrolling...
Hope this helps.
Cheers,
Mick.

Due to recent security issues and identify theft (mostly due to phishing scams), the iTunes Store seems to be requiring more frequent verification of credit card information when a card is registered in your account, even if you have a balance from a prepaid card. Either just go through the verification process or, if you have a credit card entered and you don't expect to need the card anytime soon, go into the Payment information in your account and set the payment method to "none" which should then stop the regular requirements for verification (it may still ask - mine does - but you should just be able to click through the buttons without problems).
Hope this helps.

Hi,
run same query at the same time?

I have a 16GB san disc that when more than half full and trying to download to my Mac gives a "communication error" message. How can I seamlessly upgrade the computers software to handle SDHC cards of this size?

I have a 16GB San Disc that when more than half full and trying to transfer the images to the iPhoto library I get the message "communication error". How can I update my computers software to be SDHC compatable? I can buy a card reader but thought an update to the software would fix this problem.
Thank you for any solutions or advice.

KRDHarris-
I am not familiar with Flickr, but found their support page at <Flickr Support>. You may get better help there than here. I get the impression that the App is somewhat buggy.
The iTunes preview page indicates the App is for iPad as well as the iPhone. <Flickr App Preview>

Wcf Data Service fails when more than 8properties in the 'select=' portion

Hi:
I am using WCF Data Service and Oracle
EF Provider is ODAC11.2 Release 4
Wcf Data Service fails when more than 8 properties are specified in the 'select=' portion of the URI
here is my code
var q = from c in this.ctx.SALESORDER_ITEM
select new
c.SORDERDETAILID,
c.IID,c.DMFLAG,c.OWNERID,c.SKUID,c.SKU_ID,c.TRADENO,c.SOURCEID,c.SORDERID
excetion:
InvalidOperationException: An error occurred for this query during batch execution. See the inner exception for details
The inner exception is null, but the DataServiceClientException states: Value cannot be null Parameter name: value
the exception is thrown in base.OnStartProcessingRequest(args) method (overridden).
Here is the call stack as well:
at System.Data.Services.WebUtil.CheckArgumentNull[T](T value, String parameterName)
at System.Data.Services.Internal.ProjectedWrapper.set_PropertyNameList(String value)
at lambda_method(Closure , Shaper )
at System.Data.Common.Internal.Materialization.Coordinator`1.ReadNextElement(Shaper shaper)
at System.Data.Common.Internal.Materialization.Shaper`1.SimpleEnumerator.MoveNext()
at System.Data.Services.Internal.ProjectedWrapper.EnumeratorWrapper.MoveNext()
at System.Data.Services.DataService`1.SerializeResponseBody(RequestDescription description, IDataService dataService)
at System.Data.Services.DataService`1.HandleNonBatchRequest(RequestDescription description)
at System.Data.Services.DataService`1.HandleRequest()
Is there a max number of properties in $select statement
I think may be it is oracle provider's problem ,but i don't konw how to debug it Can anyone help me
Any help is greatly appreciated

I believe the null/empty string issue is unrelated to the 8 column issue, at least for ODP.NET. For example, let's take the original query in the OBE:
http://.../yoursvcfile.svc/EMPLOYEES?$select=EMPLOYEE_ID,FIRST_NAME,LAST_NAME,SALARY,DEPARTMENT_ID,DEPARTMENT,EMAIL,PHONE_NUMBER,MANAGER_ID
Let's make all the columns selected not nullable. You can do this with the Oracle Dev Tools. Specifically, PHONE_NUMBER and FIRST_NAME are the only nullable fields. I make them non-nullable and re-run the query and the same error occurs. Thus, these values should never be made null. Moreover, in all 107 rows, none of these row values consist of empty strings anyway.
Looking into the problem further, WCF DS is calling methods in the System.Data.Services.Internal namespace.
http://msdn.microsoft.com/en-us/library/system.data.services.internal.aspx
Specifically, we see your issue when the ProjectedWrapperMany method is called. You will notice that there is ProjectedWrapper0, ProjectedWrapper1...ProjectedWrapper8 methods also present in the same namespace. As soon as the number of columns exceeds 8, ProjectedWrapperMany is called and we see the error. We're going to ask MS to help analyze the issue since this is an .NET-internal method being called.

I recently noticed that the light on the magnetic connection is always on even when it's not connected to the computer. I keep it plugged into the wall but I don't think the light was always on like that before. Is there something wrong?

I recently noticed that the light on the magnetic connection to my charger for my laptop is always on even when it isn't connected to the computer. I keep it plugged in. I don't remember it being like that in the past so I'm wondering if something is wrong.

Airport Express 2nd WAN Port light always on, even when nothing is connected.

My Airport Express 2nd WAN Port light always on, even when nothing is connected.
Is this normal? The Airport utility also said that I didn't connect anything to the port - when there is a lan cable connected from the main Airport Extreme.
The computer can connect to the WiFi from the Airport Express properly, but with blinking yellow and no internet connection, also it cannot obtain the ip address.
After setting the Airport Express to the Bridge mode, the computer cannot access to the Airport Express anymore, with "Connection Time Out" error.
The Airport Express was 3 days old, and was working properly until today. There is also one blackout today because of the storm.
Had reset the Airport several times, didn't solve the problem.

Hi again. That is a good idea. Check if router can grab an ip from your modem since wireless local connection through the router is working. If it can grab an ip and works fine on wireless, then you might have a problem with the ethernet ports. You might want to try assigning an ip address on the wired connection and see if ip of router is pingable. If really not working at all, possibility that router is not working properly anymore.

After soak test update, I get error messages repeatedly. The majority are "unfortunately, messaging has stopped", but you can replace messaging with "android os", or any other process, as it happens with more than just messaging. I have had numerous people call and ask why I didn't reply to their texts...and I look, but have not received any new texts. YES, I have restarted phone. I have cleared data as well as cache on all apps. I have downloaded the vzw messaging app, which seems silly, since it happens with several different processes and apps, but all to no avail. I am missing texts from my employer, from my family. This did happen, but rarely, before this "soak test". It is now Kitkat version 19.6.3.obake_verizon.en.US. THIS is when I started having problems...like 50 times a day kind of problems! I have seen hundreds of posts all over the internet over the past 3 days. Does no one know how to fix this??? Shouldn't there be a way to revert phone to a pre-update state? and no, hard reset did NOT work!!!! I have been with verizon for well over 15 years, but I have not upgraded my lines and will not in July either. This is ridiculous. It's not like my games aren't working, it is my messaging and "android os"...my lifeline at work!

kristinaf333,
Oh no, I am sorry to hear your messages are not working since the software update. I greatlly appreciate doing all that troubleshooting to try and get the messaging application back in business. I know how much I rely on my messages so I can understand the urgency to get this resolved. Have you had a resolution ticket opened since you started experiencing issues with your messages? Does this happen with all contacts or just some? Please provide additional information to ensure we get to the bottom of this for you.

HT6114 I cannot select more than one message at a time to delete from the trash. Any ideas will be appreciated

I cannot select more than one message at a time to delete from the trash. I did not have this problem before I updated to Maverick. What am I doing wrong?

This works in many different ways and in lots of apps.
Hold down the command key and you can select from a list (leaving some not checked) to exclude them from the delete process.
To empty all of the trash folder use command-a keys to "select all" and then the delete key to remove them.

In all probability you need to disable email scanning in your anti virus program.

How to handle more than one message coming from an async BPEL in a sync BPEL process?

Here is the scenario,
Sync process A is calling an Async process B and Async process B is developed in such a way that it is returning more than one message to sync process A, how you will handle those messages in sync process A?

As durga said, its a wrong design, you will have issues in real time. You wont get the response back most of the time. It can be otherway around, async is waiting for sync process.
Change your design or provide what is your use case below, we can think of which design suits you.
Thanks,
Vijay
