Java Exception during we click the item short description in search result

Hi Experts,
We are in SRM-MDM Catalog 3.0.
When we click a item's short description in catalog search result list to open the item detail, the new screen opened with a internal server error. And the error summary is "java.lang.NullPointerException: The relationship ID is not an optional parameter." I have validated the XML mapping, I can not find any fields which were used for the "relationship ID".
The SAP notefound in a forum is for SRM MDM Catalog 3.0 SP02 but we are using SRM MDM Catalog 3.0 SP09.Can anyone
please advise.
Below is error

Hi Sunil,
There is only one cause for Nullpointer exception. The connectivity between the source and target system no longer exist .
Please restart the MDM server once this might help .

Now I try to use 'BAPI_REQUISITION_CREATE' to instead of 'BAPI_PR_CREATE'.
But it still fail , it always give a error message like that 'No direct postings can be made to G/L acct.'.
Pls note that the ACCTASSCAT is setted to be 'M' , and I am sure that all the data entries can generate a PR without problem

No exact match was found. Click the item(s) that did not resolve for more options. You can also use Select button to choose External Data.

HI,
I have SharePoint Online 2013 environment, i have created a external content type from wcf service. I want to use this as External Data column in document library. When i look for values in content type it populates and when i click any values and adds and

I don't understand the question exactly, could you restate it. Sorry mate, I might just be braindead.
But, as far as the issue, it is by design. the column is a lookup columns which essentially ties to the external data. if that data is removed, the column on your simple list becomes invalid and any edits of the simple list item will require
it to be changed.
are you wanting to make the ECT read only? that's simple enough. you can pop open SPD and edit the ECT, then remove the C/E/D operations (create/update/delete). That will not, however make it read-only in any other systems that access that
external data, as I assume its not just SP or else it wouldn't be external

8.1.6 Java Exceptions during Installation

When installing from the Oracle provided CD the installation crashes with a java exception when I select a product to install.
I copied the entire CD onto linux and the installation completes successfully.
Any ideas?

hi radhika,
While installing oracle 8.1.6, the one of the optional tool database configuration assistant failed.(DBCA-00047 : unable to create destination directories).
so i tried to create database manually.
so i copied init.ora file as initdemo.ora and edited the file as follows:
db_name=demo
controlfiles=('/disk1/oradata/demo/system01.dbf','/disk2/oradata/demo/system02.dbf')
cdump=/disk1/oradata/demo/cdump
bdump=/disk1/oradata/demo/bdump
udump=/disk1/oradata/demo/udump
then i saved the file.
After that i created a script for database creation as "demo.sql" to create database at nomount stage.
i.e,
create database demo
logfile group1('/disk1/oradata/demo/log1.log',/disk2/oradata/demo/log2.log') size 1000k
group2('/disk1/oradata/demo/log3.log',/disk2/oradata/demo/log4.log') size 1000k
controlfile reuse;
and saved it.
I gave the following commonds at the prompt:
$export $ORACLE_SID=demo
$svrmgrl
SVRMGR>connect internal
connected.
SVRMGR>startup nomount
here i got stuck up as it is not getting starting the instance.
so i tried in SQLPLUS mode
$sqlplus
username/password: sys/oracle as sysdba
Instance is idle.
SQL>startup nomount
LRM-00109 couldnot open parameter file.
ORA-01078 failure in processing system parameters.
so can you tell me where iam going wrong.

How to import the column short description for Datastore in ODI

Hi
I am loading AS400/DB2 table in to oracle db staging tables. These AS400 table has 70 to 80 columns each with short description. Using common format designer I am able to get the DDL for the oracle db so that I do not have manually type in the table definition.
1. But how do I get the each column short description into Datastore?
2. In oracle Datastore where does the COLUMN Comments appear?
Thanks
obieefan

in snp_table->table_desc column
comments cannot be reversed when using standard reverse.
for db2 400, I suppose you can use "RKM DB2 400", i can see it reverse table comment as below
select     DBXLFI     TABLE_NAME,
     DBXLFI     RES_NAME, /* DBXFIL for system name */
     case
          when      LOCATE('<%=snpRef.getModel("REV_ALIAS_LTRIM")%>' ,DBXLFI) <> 0
          then      SUBSTR( DBXLFI , LOCATE('<%=snpRef.getModel("REV_ALIAS_LTRIM")%>' ,DBXLFI) + CHAR_LENGTH('<%=snpRef.getModel("REV_ALIAS_LTRIM")%>') )
          else      SUBSTR(DBXLFI , 1 , 4)
     end     TABLE_ALIAS,
     case DBXATR
          when 'PF' then 'T'
          when 'TB' then 'T'

Office documents does not open in the default office application from Search Results

1 WFE + 1 App Server + 1 server for OWA + 1 separate DB server make up our DEV SharePoint 2013 environment. We migrated many web applications from our SP 2010 environment to SP 2013 environment. Client integration is enabled and "Open
Documents in Client Applications by Default" feature is enabled at the site collection level. OWA is enabled and working on the search results, such as showing preview.
From the document libraries, if I open office documents like word, excel and PowerPoint, they open in the respective office applications. However, from the search results, when I try to open by clicking on the result, it opens on the browser. I want
OWA to show document preview but still want to open the document in the default office application. How to overcome this?
I have IE 8.
Thanks, Soumya | MCITP, SharePoint 2010

Go to the bottom of the Search page, you will see a Preferences link:
From there, you can set your preference. This is a per-user setting and as far as I'm aware, cannot be set globally.

Increasing the Number of Candidate Job Search Results in E-Recruiting

Hello,
Would anyone happen to know where to go to increase the number of candidate candidate job search results in E-Recruiting? It's default value is set as only allowing 10 jobs per page. If you want to display more you have to click the down arrow. How would I allow it to show, say 25, or maybe 50 per page?
Any help you can provide would be appreciated!
Thanks Ryan!

Thank you Sandra for your reply,
I tried the following combinations in table T77RCF_UI_PARAM
Name                           Param.type                            Parameters
hrrcf_unrg_srch             MAX_VISIBLE_ITEMS             25
hrrcf_unrg_srch             VISIBLE_ROWS                     25
hrrcf_unrg_srch             SEARCH_POSTINGS             25
None of which increased the number of hits that appeared on the page. The value still remained at 10 per page.
It would appear that somewhere in the result_list.bsp view for hrrcf_unrg_srch that this is being set. If I view the methods for class CL_HRRCF_UNRG_SRCH_HL_RESULT_V I find three that would appear to be relivent: PREPARE_HITLIST, GET_HITS_PER_PAGE and SHOW_HITLIST. However, I am having trouble tracking down where the default value of 10 hits per page is being set at.
Regards,
Ryan

Java exception during start of application sharing

Hello everbody,
If I push the button to start sharing an application I get the error below in EP 6.0 SP14. For me it seems that class

Hi,
It is obvious from the exception that the UITaskStatusGroupCommand is somehow not being found.
In order to confirm that,can you please Go to the following path in the Portal,
System Administration->Support->Portal RunTime->Browse Deployement
Here navigate to ROOT/WEB-INF/portal/portalapps and look for the jar file (where the class you have specified exists) in the lib folders of any of the components or alternatively use a jar class finder.
If indeed the class does not exist,then you would have to implement in a different manner.

Harish

Ocassionally, when running Firefox 7.0.1 on Mac OS X 10.6.8, I am unable to click the items of the left-most side of the Menu Bar (everything between and including the Apple symbol and "Help").

The keyboard shortcuts for all of the options still work, but will not let me select anything with the mouse. The Apple key seems also not to allow selection of anything on the Menu Bar.
I can browse normally when this happens; it's not freezing or crashing. And I am able to click everything on the right side of the Menu Bar; the clock, wireless icon, battery, etc. Also, other programs running at the same time don't have this problem. A restart of Firefox seems to temporarily fix the problem, but it's happened a few times, with no clear pattern as to what is causing it.
Anyone else having this problem? Solutions?

I fixed this, in a fairly brutal way. Here is the solution.
Save your bookmarks, like on the desktop. Or you could launch Safari and import your Firefox bookmarks into Safari, then later pull them back into Firefox.
COMPLETELY delete everything that has to do with Firefox. That includes not only the application, any dmg file hanging around and most importantly the ENTIRE contents of User/Library/ApplicationSupport/Firefox. Indeed just throw the whole Firefox folder in the Trash. Empty the Trash just in case. Now use Safari to download a new Firefox.dmg file and start from scratch. You will have to re-establish your Preferences. But Firefox will not hang, and most importantly, it will not hang your OS. --Gene

How do I make the fount of my web search results bigger

I am not able to read the web results because the fount is too small. Some pages do not let me zoom either. The settings only makes the fount bigger for typing messages.

Three ways; double tap with one finger, double tap with three fingers, or put two fingers on the screen and spread them apart.

WHEN i UPDATED TO 4, THE GOOGLE DROPDOWN DOES NOT WORK WHEN I CLICK ON THE ITEM I WANT TO GO TO LIKE IT DID WITH THE OLD VERSION.

I INSTALLED 4 AND NOW WHEN I TYPE IN THE GOOGLE SEARCH AND AN ITEM IN THE DROP DOWN IS CHOSEN, IT DOES NOT GO TO THAT LINK. THE FEW LETTERS I HAVE TYPED IS ALL THAT SHOWS UP IN THE BOX AFTER I CLICK THE ITEM IN THE DROP DOWN.

Can I change back to the older version of Firefox

DefaultListModel & JTable; how to sync the items in the DefaultListModel

I have a jtable with items in it
example
name date age
Peter 01-jan-43 62
Ron 03-nov-73 32
when double clicking the name( eg peter), a new window pops up contains all relevent info of the user.
I added a sorter and when sorting the table it comes in the correct-wanted order, however, when double clicking the item - the wrong window pops up.
I take it the DefaultListModel is not synchronized with the tables elements.
Q: how to correct the DefaultListModel once the table has been sorted so it will be in sync with the jtable.
thanks
peter

thank you camicker for replying.
I have been trying for the past 4 hours to dig in the code (as well as google) to find where to implement a sync with the DefaultListModel. Nothing.
any input?

Hi,
I am getting the following error in XI 3.0 SP12.

and in the trace of that messages the error is as follows:
System_Error HTTP-Client: exception during receive: HTTP_COMMUNICATION_FAILURE
The scenario is a BPM in which calling a BAPI using RFC adapter Synchronously and after getting the response from BAPI generating a file for that response data.
I think message is failing in receiving response from BAPI.
Kindly reply me back ASAP.
Thanks

Hi,
Can you check SICF services are active or not. in Transaction SICF.
Also Check the HTTP ports (using transaction SMICM choose Services),
Check RFC adapter Configuration, Gateway, etc

Exception during room creation

Hi everybody,
First time I'll use collaboration. I'm using EP 6.0 sp9, I just applied patch 3 for KMC.
I'm trying to create a collaboration room, but the last step (finish button) gives me this error:
"Error: Room MyRoom has not been created
Exception during room creation"
The log file line:
#1.5#000BCDEFE483004E0000000300000EA80003F06AF3055684#1108767064581#com.sap.ip.collaboration.room.api.Exceptions.RoomCreationException#sap.com/irj#com.sap.ip.collaboration.room.api.Exceptions.RoomCreationException.logException(268)#diego.hernandez#475####7b431de081ff11d9ab18000bcdefe483#Thread[PRT-Async 0,5,PRT-Async]##0#0#Error##Plain###com.sap.ip.collaboration.room.api.Exceptions.RoomCreationException: Exception during room creation
Any clue about this ? I appreciate a lot your help !!!
Regards from Mexico,
Diego

Hi Veronica,
Well... I guess its an installation problem. Because I install another EP instance (with other source files) and everything is working correctly. In fact, I have installed a lot of SR1's and they're working fine. You should try another source files and reinstall the solution.
pd: I think this is the most clean and fast way to fix the problem... Obviously, you can try to fix it with patches, fixes, etc.
Regards,
Diego
