Hi Ravi,
Have you filled in the node_vbak1 with some elements? Lets say in a supply function or wddoinit etc.?
Just check that. After that, make sure you have IntializeLeadSelection property set to true for the node_vbak1.
Hope this helps.

Getting error on Portal : Access via 'NULL' object reference not possible

hi friends,
While executing a bapi,I am getting this error : Access via 'NULL' object reference not possible., error key: RFC_ERROR_SYSTEM_FAILURE
I am calling a bapi with only one required parameter from Portal as per the design of the bapi and the bapi itself is calling some other functions internally.
I a using ECC 5.00 i,e. EA-HR 5.00. On SDN it is suggested to Apply OSS Note 1018036. But it is applicable to EA-HR 6.00 and subsequent releases,I guess.
Need your suggestions and also need to know if the above Note can be applied to EA-HR 5.00.
P.S: Points would be assigned, thanks is advance.

Portal not accessable via browser as inside sapmmc - http provider is red

Hi Experts,
I am very new to NW admin side and currently my client is facing an issue while accessing portal via browser.
Problem: Some times suddently when users try to access production portal it takes a lot of time to open up and in most cases it doesn' t get opened up at all. To check what' s wrong with the portal i access sapmmc and inside their i find under current status -> ... -> services -> http provider -> total requests in red status with a description as avg request - response time last reported value above threshold limit. It will be the same case under open alerts too.
My server configuration is:
SAP-JEE = 7.0SP14
OS = Windows 2003 (X86) 5.2
Server Version = 1.4.2_17-bo6
Kernel Version = 7.00 patch level 109886.44
Server = 32 bit
RAM = 16.00GB
Processor = Intel(R) Xeon(R) CPU E5450 @3.00GHZ (8CPUs)
Heap Size: 1024 MB
Approximate number of users = 500 - 600
Currently to solve the issue, we give a reboot to server. But with the progress in time the frequency is getting increased drastically (approx once in 2- 3 days).
Any pointers on how to solve this issue will be greatly appreciated.
Thanks In Advance,
Vipin.

Hi all,
Thanks for your valuable inputs!
Now the issue seems to end up by raising an OSS notes with SAP and i have been given responsibility to prepare a doc that needs to be submited to SAP.
I have already got the screenshots from SAPMMC on it' s status and all, but also requires log information specific to the reason behind this behaviour. Can i know where the log information specific to such issues gets logged and all the necessary information that i need to document to raise an OSS.
Inputs with be of great help and will be highly appreciated.
Thanks In Advance,
Vipin.

Requirement to check the syntax error of Customize SAP Objects in existing landscape.

Hi All,
I have two requirements which are a s follows :
1 ) Check the syntax error of customize SAP Objects in existing landscape except using the Tools which are already given by SAP( Example : Code Inspector , Extended Syntax Check etc.). I have to create a program to fulfill this requirement.
2 ) In case of SAP Upgrade is it possible to know the syntax error in advance that the existing source code will not work in the upgrade version?
Please help me out to solve my issues. Thanks in advance.

Dear Abhishek,
For the code inspector, the syntax check and the extended syntax check, you can define a set of objects to be teste thru SCI:
Go to SCI
In the block 'Object Set', you can create a set. For ths, you have to give it a name, select with the icon left of the textbox if this is a global (for all users) or a local set and click the create Icon.
in the next field, you can define which objects ... are part of the object set.
When using SCII to execute the code inspector, you can specify this set instead of a transport(s) or programming objects.
To run only the syntax check and or the extend syntax check, you can specify a check variant in SCI (third screen block) which contains only those tests or you can in SCII uncheck all tests except those 2.

Hans

Working with the Portal Error Stack in PL/SQL

Hi,
In brief, this is a question about the persistence of errors on the stack, as they appear to disappear without warning. Any help would be appreciated, if you'd like background, read on.
I'm writing PL/SQL web applications and as ever one of the required tasks is user validation.
I have a form on a page which submits directly to a stored procedure. If the validation within the proc is ok, the value(s) get inserted into a DB table and the user gets directed to another Portal page. If there is a user input error then the code reloads the original page (via redirect) with the necessary errors displayed.
I used to use the Session storage to hold any error messages and then check to see if any errors existed at the point of page redirection, and this worked fine.
Now that I figure that I should do the job properly and use Portals' error stack, everything falls over!
It would seem that between moving from one page to another any values held in the stack are lost, yet I know they are definitely getting put there in the first place as I can view them, as long as I don't redirect the Portal page.
Any ideas??
Thanks in advance.
Dan

1.) Create a hidden item on your page.
2.) In your Page Rendering PL/SQL Process add logic which assigns 'EDIT' or 'NO_EDIT' to the hidden item.
3.) Create a "Message" HTML region which conditionally displays based of the value of your hidden item being 'NO_EDIT'.
4.) Make your edit field conditionally Read Only based on the value of your hidden item being 'NO_EDIT'.
There may be an easier way but I got this to work

Track the qeries that accessed a particular object during a time period

HI,
I have a list of objects on my schema and i need to track the list of sql queries by different users that accessed by object during this time period.
i haven't enabled any auditing yet.
is there any way i can get that list of queries and their schemas that accessed those particular objects during a particular time period.
Can someone guide me please.
Thanks in advance.
Philip.

Too bad you don't have a version number. Oracle functionality changes from version to version and in some versions you can do this and in some you can not.
Look here for one way to accomplish the task:

The supported JBoss version for 10.1.2 is JBoss EAP 5.1.2 but I don't think that your issue is caused because of this. Your issue is more of an environmental thing as you are probably getting two different versions getting loaded of class javax.servlet.http.HttpServletRequest and so correspondingly two different Class objects as the error shows. One reason for this could be if you include any server-specific libraries (in present case the Servlet API JAR which contains the class javax.servlet.http.HttpServletRequest) of a different version in the /WEB-INF/lib of your web application. Try removing it from there if so and see if that helps.

Using a Link in a Webtemplate to navigate in the portal

Hi BI/Portal experts!
We are using a federated portal environment. in our consumer portal we have implemented a reporting system with an overview page and some detail pages. each page contains iviews with webtemplates from our consumer portal.
In the overview page we have a iview with an web template wich holds some key figures and a link. Our aim is to use that link to get to the details page (which is somewhere else in the navigation). We tried to use the "NavigationTarget"-technique but the result was that the detail page was opend in the iview window instead of the full explorer window.
Is there any possibility to have a link within a webtemplate that affect the whole portal and not only the iview of the template?
I hope i could make myself clear.
Thanks for any help or hint
Regards, Alex
Edited by: Alexander Paulus on Feb 12, 2008 2:58 PM

Hi,
You need to load detailed page in same window after clicking a link in overview page?
How you implemented overview page, is it a template or seperate html page?
If it is a template then you can open detailed template in the same window from a link in overview page. For this you have to set open template in same window parameters in your link.

How to make a relationship with the portal Id with R/3 Id

Hi Experts,
We have developed a portal application and assigned the role to the User.
In R/3 where we can integrate the details.If we maintainin IT 0105 communication,will it suufice the need.
Please advice.
Regards,
Vikram.

Hi Vikram,
And I add by saying that:
1. The user from the portal have the portal roles (access to portal applications)
2. This same user have the roles, groups and profiles on the backend to permit or deny access to the authorization objects (which permit access to ITs on the HR and tables)
3. The Pernr that you assign this user via IT0105 STy0001, is used on the org structure.
Hope I contributed.

Broadcasting PDF file to the Portal via Bursting

Hi there,
I have a requirment to send a Business Partner specific version (filtered by a different BP id) of a report to the portal as a PDF for 250 different business partners.. These PDF files will then need to be externally exported from the portal for dustribution via direct mail.
The reason for this is the the business partners to not have access to the portal and many do not have valid email addresses.
If this a feasible scenario ? Bursting seems to only be a possible option for email ?
or can i create 250 different versions of the PDF in a KM folder in the portal ?
Help greatly appreciated.
Mark

Hi Patrick...
No at this point I have not made any headway with this... just beginning to look at it again today? have you had to do anything like this ?
