Creation of Personal Object Worklists - can anyone help...?

Hi All,
We have a portal where in which the end users(actually power users) can view reports, run queries within the privileges of their authorizations,change queries and save them etc.....
All the data for the reports comes from ECC(backend).
Given the above situation I want to create a Personal Object Worklist(POWL).
POWL is totally new ,hence i need in-depth info ;would be really helpful if someone can explain the concept of POWL comprehensively please...!
All valuable help will be appreciated through fitting points!!
Thanks and Regards,
Sai.

hei, try to look into this link

can anyone help with facetime? im getting missed calls but it doesnt actually come up with an incoming call.....the person im trying to contact just gets missed calls also?

I've noticed that once you miss a call on FaceTime on a desktop Mac, it won't work properly again until you restart the machine.
I sent in Feedback so we'll see how that goes.

I am trying to transfer the licence of a Dreamweaver CS3 Macintosh product. A transfer of licence form has been signed by the person that gave it to me. Can anyone help me complete the process?

I am trying to transfer the licence of a Dreamweaver CS3 Macintosh product. A transfer of licence form has been signed by the person that gave it to me. Can anyone help me to complete the process as Adobe chat say they cannot to help? They told me the forum is looked at by an expert team. Anyone there? Thanks

Did you complete your form as well? A form needs to be completed and signed by both parties and submitted to Adobe support via a support ticket. Chat support cannot help, but should have pointed you to the KB article with the instructions.

Nobody here is responsible for what is or is not available in any country. I believe it is a software licensing thing.

Pay no attention to iinami, the amount of replies to people saying their handsets must have been jailbroken everytime iTunes throws out an error is tremendous. (Clearly you don't need to have any real knowledge to get to level 3 on these forums, let's hope apple's geniuses know a lot more than some of their customers.)

Solution below.
Error 9
This error occurs when the device unexpectedly loses its USB connection with iTunes. This can occur if the device is manually disconnected during the restore process. This issue can be resolved by performing USB troubleshooting, using a different USB dock-connector cable, trying another USB port, restoring on another computer, or by eliminating conflicts from third-party security software.

I don't understand why a person who has been with a company for 6 years cant get a simple upgrade can anyone help figure that out?

I don't understand why a person who has been with a company for 6 years cant get a simple upgrade can anyone help figure that out?

Are you trying to get an upgrade before you're actually eligible? If that is the case, it doesn't matter if you've been a customer for 6 years or 6 days...if you're not eligible then you're not eligible. Some of your possible options are to pay full retail, do an early edge up (if you are eligible for that option), or buying a phone from some other source to use.
If your situation is something different then it might help to share that. The options may still be the same but it helps to know what exactly the issue is.

Update to above question:
Hello All,
To anyone with the same problem described above, on THEIR iPad (if it is running iOS 7.0.2):
Go to Settings; Mail, Contacts, Calendars; DELETE your *******@btinternet.com e-mail account, that you originally set up either using 'Other', or the 'BT' option which I am sure was in the list previous to the iOS 7 update.
Then ADD a NEW account choosing YAHOO from the list of options. DO NOT USE 'OTHER'.
Enter the correct details just as you (almost certainly) had already done in your previous attempts using 'other'.
When you see the 'verifying......' and 'the blue ticks' you should be able to exit settings and open your mail app and then receive all your 'old' e-mails again, AND be able to SEND as well.
All my 'old' e-mails, were NOT found in the 'old e-mail' folder though. THEY are still in my inbox.
So this fix worked for me.
After I deleted my account from 'OTHER' and put it in Yahoo, I like other people also ended up with more folders.
I hope this works for you on YOUR Apple devices.
Bob

Hi, I am using an iMAC 6.4 and I will need to upgrade the 10.5.8 to a newer version. I am a PC person, so I have no idea of how do this. Can anyone help me please? Thanks!

e no idea of how do this. Can anyone help me please? Thanks!

There is no such model as an iMac 6.4. Be sure to check the system requirements for upgrading.
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
         7. Xserve (Early 2009) - Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
     Are my applications compatible?
         See App Compatibility Table - RoaringApps.
     For a complete How-To introduction from Apple see Upgrade to OS X Mountain Lion.

If Dreamweaver shows a message saying "the following JavaScript error(s) occurred", it's usually a sign of a corrupt cache file. The first thing you should always be to delete the file cache. If that doesn't work, delete your personal Configuration folder. Please go through the steps mentioned in thread Deleting a corrupted cache file.

Personal Object Worklist (POWL)

Hi Everyone,
I'm a newbie in Portal content so please give an answer in the simplest of english.
Q : What does a POWL in the context of an Enterprise Portal User mean/offer??
Thanks and Best Regards,
Sai

>>what POWL is all about>>
The Personal Object Worklist (POWL) provides you, as an Enterprise Portal user, with a general overview of your work environment and all related business objects that you would be interested to work on. It enables you to manage your work efficiently and aids in decision-making. POWLs are most suited to assignments that are not a part of a workflow.
>>its use>>
Function
Gives you a unified and centralized way to access your work and the relevant information
Aggregates non-workflow task items from multiple and different systems in one universal list
Displays additional information as required from document and object repositories, including attachments and other details such as worklist type dependent actions
Provides easy entry into business object handling in detail and also in presentation of work items
Example
Consider a production order-related worklist; based on a predefined selection variant the Production Supervisor (portal role) gets a worklist with planned orders for his or her section of a plant, including a workshop, which is represented by all materials belonging to the same material class.
The Production Supervisor can now select one or more planned orders, convert them to production orders, release the orders, print the work instructions, and distribute the worklists to the responsible operator groups.
>>whats it based on>>
You can find the settings and configurations here
http://help.sap.com/saphelp_erp2005vp/helpdata/en/42/d6652b755c1630e10000000a1553f7/content.htm
>>its use in contrast with WEB DYNPRO>>
It is an ABAP Webdynpro Application and part of Netweaver 2004s so you can create a Webdynpro iView for ABAP in Portals using the following link
http://help.sap.com/saphelp_erp2005vp/helpdata/en/44/451e7582190a64e10000000a422035/content.htm
A POWL (Personal Object Work List) is an individual list generated by query that provides an overview of the user's working environment by presenting one or more list of objects, as a set from which the user can select items to work on. There are some POWLs which are already predefined and delivered together with the applications available in the SAP NetWeaver Portal. However, if the default POWLs do no meet the customer requirements, it is possible to change the query values or to assign different POWLs to the application you like.
Configuration Settings in the Backend System:
1. Log on to the backend system <System ID> you want to configure
2. Start the transaction POWL_QUERY
3. Click on button New Entries
4. Enter a name for Query ID and the corresponding Description.
5. Select an available Type via F4 help
6. Save your query definition
7. Go back to the Main Table View: Initial Screen and select the Query youve already created
8. Click on Details or <Ctrl-Shift-F2>
9. Click on button Query Parameters
10. Fill in some values for one/more selection criteria
11. Save your changes
You may need to assign the POWLs you would like to display for a specific Application (e.g. Customer Fact Sheet). In order do this, you should do the following:
12. Start transaction POWL_QUERYR.
13. Click on button New Entries
14. Select as Application via F4 help the application you would like to assing the queries to (e.g.value O2C-CUSTOMER_FACT_SHEET) and as Query ID the query youve already created. (Note: Not all the POWLs may work for the application you want)
13. Mark the checkbox Activate and save your entry
To test if the POWLs you've defined display correctly on the SAP NetWeaver Portal:
1. Log on to the SAP NetWeaver Portal
2. Open the Application you would like to test and for which you assigned the POWLs (e.g. Customer Fact Sheet) and, check if the queries are available.
Please follow the following steps to create a powl worklist and see it using the powl application .
1) implement the feeder class IF_POWL_FEEDER. Details about this can be found here http://help.sap.com/saphelp_erp2005vp/helpdata/en/42/d6652b755c1630e10000000a1553f7/frameset.htm
2) Maintain an application id using the transaction FPB_MAINTAIN_HIER
3) Go to transaction POWL_TYPE to define a powl type. point it to your newly created class.
4) Next in the transaction POWL_TYPER maintain the newyl created powl type with the application id.
5) Using transaction POWL_QUERY create a default query. In this step you will have to specify the type of query (again the powl type). Here you will be mentioning the type of query.
6) using POWL_CAT maintain a category. The category is used to group multiple queries of the same type.
7) In POWL_QUERYR maintain the default query created with the application id and the category.
8) call the powl application with the applid.

I think this is what you are trying to do. Your code was not very clear so I wrote my own:
