Error in Web Srvice while SSO to RFC in the ECC system

Hello Folks,
I am creating an Web Service out of EJB to connect to ECC with an SSO(Logon ticket) based Modeldata JCo for which I get an error (Log provided below). When I create the Modeldata JCO with UserID/Pass it works fine.

Web template "0ADHOC" does not exist in the master system error

Hi to all,
The Web template "0ADHOC" does not exist in the master system.
Error coming while executing query on web template.
Via TCODE RSCUTV27 I have checked the default web template 0ADHOC is already there for adhoc analysis.
Please can anyone tell me what the problem is?
I shall be thankful to you for this.
Regards
Pavneet Rana

Hi,
According to the error message,
The template ""0ADHOC" does not exist in the BI system. It has to be transported too.
OR
Logon to R3 and check in Transaction SE38 with program "RS_TEMPLATE_MAINTAIN_XX".
You will see
                                     Template ID :
                                     Reusable Web Item ID :
                                     Version :
Give "template name" and see what is the version.
If it is "D" then please change that to version "A". and check if issue persist.
Hope this helps.

The definition of the READ RFC to the managed system could not be found. Pl

Hi there,
i try to setup a managed system on our Solution manager for E2E Analysis... but the Setup gave me a sort of errors
The definition of the READ RFC to the managed system could not be found. Please make sure to run the RFC creation assistant in SMSY, as described in setup documentation
and
No RFC Read User (SOLMANSOX001 or SM_SID) was found at ABAP Host=HOST sys=00 client=001 for roles assignment. Please make sure you have run the RFC creation assistant for this system, in SMSY. If a user name different from the default 'SM_<SID>' or 'SOLMAN<SID><CLIENT>' was specified in the SMSY RFC creation assistant, you need to assign by hand the following roles & profiles to the Read RFC User : SAP_SATELLITE_E2E (role), S_AI_SMD_E2E (profile)
So which documentation means the setup where is described how to create the RFC Destinations with SMSY.. Thanks

Erorr " The Web template "0ANALYZER" does not exist in the master system "

Hi
i am trying to run query from Query designer and execute in Web .i am trying to execute this in query designer. i am getting below error.
"The Web template "0ANALYZER" does not exist in the master system "
i activated all templates but not able to execute any report in web
i am able to execute same report in webaplication but not thru query desinger... do i need to setup anything.?
please do help me

For clarification:
If following happens:
> you are launching the query with URL like:
http://<server>:<port>/irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fcom.sap.pct!2fplatform_add_ons!2fcom.sap.ip.bi!2fiViews!2fcom.sap.ip.bi.bex?QUERY=<your query name>
> then you get the error message "The Web template "0ANALYZER" does not exist in the master system"
--> then you should check the settings for default templates in SPRO. Please mention that the default Web Template for query execution (BEx Web Analyzer) is called 0ANALYSIS_PATTERN.
--> also check the 0ANALYZER Web Template in SE38 / Program: RS_TEMPLATE_MAINTAIN_70 -> then check if the template is active.
When you problem is other nature you have to describe it in detail.

Access denied error while writing a file to the file system - myfileupload.saveas() throws system.unauthorizedexception

hi,
as part of my requirement , i have to perform read and write operations of few files [ using the file upload control in my custom visual web part] and on submit button click.
but while writing these files - with the help of fileupload control - and when i use myfileupload.saveas(mylocation);
- i am saving these files into my D:\ drive of my server , where i am executing my code -, am getting access denied error.
it throws system.unauthorizedexception.
i have given full control on that folder where i was trying to store my attached files. and also after following asp.net forums,
i have added iusr group added and performed all those steps such that, the file is saved in my D:\ drive.
but unfortunately that didnt happen.
also
a) i am trying the code with runwithelevatedprivileges(delegate() ) code
b) shared the drive within the d :drive where i want o save the files.
c) given the full privieleges for the app pool identity- in my case , its
network service.
the other strange thing is that, the same code works perfectly in other machine, where the same sp, vs 2012 etc were installed .
would like to know, any other changes/ steps i need to make it on this server, where i am getting the error.
help is appreciated!

Hi Friends,
I have gone through scores of examples and i am failing to understand the right thing to be done to copy a file from one directory to another. Here is my class...So let's see... C:\GetMe1 is a directory on your machine, right? And this is what you are doing with that directory:
public static void copyFiles(File src, File dest) throws IOException
// dest is a 'File' object but represents the C:\GetMe1 directory, right?
fout = new FileOutputStream (dest);If it's a directory, where in your code are you appending the source file name to the path, before trying to open an output stream on it? You're not.
BTW, this is awful:
catch (IOException e)
IOException wrapper = new IOException("copyFiles: Unable to copy file: " +
src.getAbsolutePath() + "to" + dest.getAbsolutePath()+".");
wrapper.initCause(e);
wrapper.setStackTrace(e.getStackTrace());
throw wrapper;
}1) You're hiding the original IOException and replacing it with your own? For what good purpose?
2) Even if you had a good reason to do that, this would be simpler and better:
throw new IOException("your custom message goes here", e);
rather than explicitly invokign initCause and setStackTrace. Yuck!

Error in Outbound Queue while Releasing order from CRM to ECC

Hi,
When I release my sales order from CRM to ECC, I got an error in Outbound Queue saying "Screen output without Connection to User".
This is occuring in FM : BAPI_SALESDOCU_PROXY_UPLOAD
Can you please tell me why this error is coming?
Thanks,
Sandeep

Hello Sandeep,
During the RFC call from CRM to ECC, this is a background processing, the screen call is not allowed.
If a call screen is executed, there is the mentioned error.
Please check in your ECC system, whether you have any user exits that have the coding 'call screen'.
Best regards,

What does the error message -50 mean while trying to connect to the iTunes Store?

I got this error message while trying to connect to the iTunes Store. -50. Does anyone know what that might mean? For almost two months I have been unable to use my iTunes with my iPod-because my iPod is not being recognized in iTunes. I have done every troubleshooting thing possible-including completely uninstalling and reinstalling iTunes, eight different times. Please help. Super frustrated.

iTunes: "-50" alert when syncing your iOS device to iTunes 10.3
iTunes displays -50 error message when syncing iPod on Windows XP
"Error -50," "-5000," "8003," "8008," or "-42023"
These alerts occur due to timeouts or conflicts trying to write a file during download.
If you encounter this issue while accessing iTunes Store:
See iTunes 9: "One Moment Please" or "Error (-50)" message when accessing iTunes Store
If you encounter this issue while while downloading something from the iTunes Store:
Delete your iTunes Downloads folder, located in:
Mac OS X:  ~/Music/iTunes/iTunes Media/Downloads Note: "iTunes Media" may appear as "iTunes Music. Also, the tilde (~) refers to your Home directory.
Windows Vista:  \Users\username\Music\iTunes\iTunes Media\Downloads\
Windows 7:  \Users\username\My Music\iTunes\iTunes Media\Downloads\
Windows XP:  \Documents and Settings\username\My Documents\My Music\iTunes\iTunes Media\Downloads\
After locating your iTunes Downloads folder:
Quit iTunes.
Delete the Downloads folder on your computer.
Open iTunes.
Choose Store > Check for Available Downloads.
Enter your account name and password.
If you encounter this issue while while downloading Digital Copies using Windows:
Use MSCONFIG (directions for Windows XP and Windows Vista/Windows 7) to disable conflicting software.
If using MSCONFIG steps resolves the issue, you may want to use the System Configuration Utility to turn on the third-party System Services and Startup Items one at a time (restarting your computer after turning on the item or items) to identify which System Service or Startup Item is causing the conflict.
You can turn all of them back on by selecting the Normal Startup option under the General tab of the System Configuration Utility window, but please note that this may cause the issue to reoccur.
If you are able to isolate the issue to a particular third-party software, you may wish to contact them to let them know of the conflict.

RFC Call to ECC system

Hello Friends,
Need input from you with regards to the Problem/Solution mentioned below:
Our requirement is that during the load of FI data from our Centralised ECC System, we want to retrieve the Billing document details from a new ECC System. Since we need only the Billing Doument and Count of Item data from this new ECC System we dont want to proceed with the regular way of Establising Source System connection and creating new Datasources etc.
The Solution we have thought is to set up a RFC Connection and Execute a Function Module during the Routine execution in BW. Thie Function Module will be executd in the new ECC system and will retrieve the required Billing details.
If you have faced similar situation and implemented any other solution then please let me know.
Any help is appreciated!
Regards,
Nitin S.

Hi Nitin ,
The solution sounds good . The only problem which i found in this is suppose for any reason your RFC does not work for a day or two . Then the FI data will be loaded without billing information . It will be a difficult task to reload the FI data again for the missing Billing Information .
I assume that your FI postings are happening in Centralized ECC while correspong Billing Docs are in New ECC . So the two ECCs have a RFC conncection between them :
Following approaches can be taken :
1) As per your solution you are going to call the RFC in BI . Instead of doing it in BI , do the same thing in the enahncement of the FI Datasource i.e make a call from centralized ECC to your new ECC . This will affect the extraction performance , but your loading performance will be improved .
2) Is there a possibility that you can flow your billing documents to your centralized ECC and then do a datasource enhacement of the FI datasource .
Hope the above reply was helpful.

Ashutosh Singh

Error in webi report while refresh

BO XI 3.1 Sp2
windows server 2003
SAP BW NW 7.0
Reports are working fine till yesterday. Today when we refresh webi reports getting below error
*"A database error occurred. The database error text is: Error getting variable for cube "XXX_XXX/XXX_XXX_XXX". Unknown error (WIS 10901).*
All webi reports are getting same error.
Tried to verify iin CMC. We have two entitlement systems in CMC. QB1, QB2. Verified all username/passwords. And every thing is working fine. Imported all sap roles. Every thing was working fine till yesterday.
But when I verified in user/groups, I am able to see all SAP roles of QB1. Very few sap roles of QB2.
Please help me.
Thanks,

Hi,
I think your BASIS may have done something in the BW side, as i've seen this kind of problem when importing wrong transport and overwriting content.
As a test, try hardcoding the Universe connection with a named SAP_ALL user instead of using SAP SSO
FWIW - SP02 is no longer supported . SP03 is no longer maintained (last FP3.8 is due soon)
most reference customers are on XI 3.1 SP04 FP4.1 or XI 3.1 SP05 with BW 7.01 SP09/10
From your description, i can't tell if you are using EhP1 or not. ( you really should be)

Hi,
Can you plz help in my issue .
Dear Gurus,
Find the below scenario followed by us.
1.Created the service order with the ZSR3 procurement item category.
2.PR created for the service order 35035201 in ECC with no 0070088937.
3.One queue is struck with the below details.
4.If we re process the queue it will process with out any error and then only our document flow of the CRM service order line item.
Plz check the queue name R3AD_CRM_SRV_0035025201 in CRM system from
Tcode SMQ2 which is in SYSFAIL status. The corresponding BDOC in SMW01
tcode has validation error message " Module CRM_SRV_EXT_VAL, BDoc type
CRM_SRV_XTN. Message no. SMW3018 " . Plz advise.
As per my understanding and debugging i think it might be a issue
As a standard CRM any change/update in ECC document 0070088937 should
send back the information to the source CRM document with header GUID
4E6527B4D3070C10E10080000A8C6828 . But system is referring to a
different GUID where there is no document exist in CRM.
Pls find the root cause to trigger different GUID when information is
passed from ECC to CRM system.
Best Regards,
Prakesh

PI 7.31 (single stack) posting RFC gives this error: RFC_ERROR_SYSTEM_FAILURE: Processing of change number CO-01234 cancelled (raised by system ECCHostXYZ)

I'm trying to determine if I am dealing with an RFC connection issue or just an error resulting from the RFC itself.
The error says "Processing of change number...cancelled (raised by...ECCHostXYZ)".
I thought this was a problem with my RFC config because it is labeled as "RFC_ERROR_SYSTEM_FAILURE".
However, when I google that specific message, it appears to be an error specific to change order creation.
Here’s my google search: http://goo.gl/ZhKsm3
Here is the error again:
RFC_ERROR_SYSTEM_FAILURE: Processing of change number CO-01234 cancelled (raised by system ED1|ecc-host-xyz)
When I check ST22, I see no RFC errors.

Hi Jody,
No st22 exception is needed to be throwed in order to raise a controlled exception in the RFC.
You would need to check the RFC in the ECC system with the data that you are sending from PI, if the data is the same, you would need to check PI user RFC roles with the ECC roles user that you used to check the data integrity in the ECC test.
To avoid this error you can do a Z RFC to wrap the standard RFC and to control the exceptions errors with a BAPIRET2 strucutre to return to PI.
Hope this helps.
Regards.

How to call a RFC of a remote system from an ABAP webdynpro component

Dear Experts,
I am a newbie in ABAP Webdynpro.
I am working on a requirement where I have a webdynpro component on ECC system.I need to call a RFC located on CRM system from my webdynpro component on the ECC system.
How do I do that ?? Please help.
Regards,
Mamai.

Calling RFC from some other system is same as local except the difference is that you have to give destination name while calling.
And the regarding the method of calling it depends on your FM.
if it is big RFC with complex structure, you can create the service call for it with destination given as RFC desitination.
if it is simple straight forward RFC you can directly call it.
for creating RFC service call call use this method
1. Starting the Wizard
To start the wizard, position the cursor on the Web Dynpro component to be edited in the object list at the left margin of the
workbench window. Open its context menu and choose the entry Create->Service Call. The wizard is started and leads you
through the creation process.
Press Continue.
2. Choice of Controller
On the second dialog window of the wizard, you can choose whether the service call is to be embedded in an existing
controller or whether a new controller is to be created for this purpose. Service calls can only always be embedded in
global controllers u2013 that is, in the component controller or in additionally created custom controllers. It is not possible, to
embed service calls in view controllers.
a. Select radio button Use Existent Controller
b. Do not change the default entry for component: <CC name>
c. Enter for controller COMPONENTCONTROLLER
d. Press Continue.
3. Service Type and Service Selection
a. You now select, which service type should be used for this service call. Select radio button Function Module. Fill the
destination here. Press Continue.
b. Select the service: for Function Module enter <RFC name>. Press Continue.
4. The Required Methods and Context Elements
On the two subsequent dialog windows, default values are listed for giving names to the context nodes and attributes
required by the service call as well as to the required methods. The proposed names are based on the names of the
embedded service, but you can change them as required. However, heed the respective notes in the corresponding dialog
box.
a. Adapt Context: Select from Nodes/Attributes . Press Continue.
b. Specify Method Name: leave all entries as provided: Component: Controller: COMPONENTCONTROLLER Method: EXCUTE_ Press Continue.
5. Completing the Choice
When you have confirmed the last dialog box, the generation is triggered. Afterwards you now have the required methods
and contexts at your disposal for using them within your Web Dynpro component.
or if you want to call directly the use the call statement with destination

Hi Justin,
SSO logon not possible; logon tickets not activated on the server
Please check your WAS Profile Parameters in RZ11:
For enabled SSO,WAS should have the possibility to create and accept SSO-Tickets. For that the Profile Parameters should be:
login/create_sso2_ticket = 2
login/accept_sso2_ticket = 1
