Which roles are needed to call a BAPI in an ERP system?

Hi,
in a scenario I use a SOAP Receiver adapter to call a BAPI in an ERP system. In the SOAP adapter I configured User Authentication.
The question is which role(s) does this user need that this scenario could work?
Thanks and regards
Patrick

Hi,
> I think this would be RFC Receiver Adapter )))
No I use the SOAP Adapter to call the BAPI
@ Siddhesh: I tried it with the roles given in your link
- SAP_XI_ADMINISTRATOR_J2EE
- SAP_XI_APPL_SERV_USER
- SAP_XI_DEVELOPER_J2EE
- SAP_XI_IS_SERV_USER
But it's not working with these roles

Which files are needed for connection to database in 11gR2?

I'm confused about the following files:
sqlnet.ora
tnsnames.ora
listener.ora
host file
If I understand correctly, sqlnet.ora and tnsnames.ora can exist in both client and Oracle database server and listener.ora should only exist in Oracle database server. I guess host file can exist in both client and Oracle database server.
I'm trying to understand which of the files are needed to access Oracle 11gR2 database using different tools such as
sqlplus, SQL Developer, and Database Control on Oracle database server or from a client machine.
If I'm on an Oracle database server, which of the files are needed for accessing 11gR2 database on that server for the different tools?
If I'm on a client machine, which of the files are needed for accessing 11gR2 database on an Oracle database server for the different tools?

Some of the config parms available to it apply only to the server side, some apply only to the client side, some apply to both.
tnsnames.ora is used by client processes to resolve a connect alias to a specicific host, port, and service. It is used ONLY by the client side of tns. You see it on host machines because those machines can also run client processes.
host file. Oracle doesn't know what this file is. Oracle doesn't give a flying fig about this file. It is used by the standard network software in the OS to resolve a name to an IP address. The only reason you even see it discussed in the Oracle world is because Oracle TNS sits on top of the standard OSI network stack, and uses it. Thus, if your tnsnames file has an entry like:
houston =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = vmlnx01)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = houston)
#==========tns will never know or care where vmlnx01 is. The request will be packaged and sent to the standard network stack with a request to "route this package to vmlnx01, wherever that is.". The OS network stack will then resolve 'vmlnx01' to an ip address, by one of several possible methods. ONE of those methods is to look it up in the local hosts file.

HOW DO I FIND WHICH PLUGINS ARE NEEDED on pages that dont display?

Question
when i loginto my.t-mobile.com i get a circle of moving dots in a white screen over top of some of pages, and some pages have a moving circle like the QuickTime circle in place of the curser. i know its because ff needs a plugin or something installed but dont get info from ff as to what is needed. this site works perfect in IE8 (after IE8 loaded unknown to me which ones) some plugin.have upgraded to FF8, same problem. had same type problem on IRS free file website where pages wont show, but worked perfect in IE8. problem has to be that a plugin or addin needs to be installed but i can't get any info about which to work on.

Very few apps actually run in the background, so, if you're talking about removing apps from the recently used list, that's unlikely to have any significant affect on your data usage. You should go to Settings>General>Background App Refresh and turn off background app refresh for those apps that you don't need to have using data in the background.
You can go to Settings>Cellular and scroll down to see which apps are set to be able to use cellular data. Under each app name is the amount of data they've been using.

Which cables are needed to connect macbook 13" to HDTV

Hi, was wondering which cables i needed to connect my 13" aluminium macbook to a samsung HDTV. There's so many on the apple store, not entirely sure what I need. Any help would be appreciated.
thanks

Can you clarify whether you're using a MacBook Pro or a PowerBook? Your post is ambiguous. For good measure please tell us when it was purchased new.

Finding out which jars are needed

I am using an open source library. I am only using a fraction of its functionality, and the library is huge (it drags in many other JARs from other OS projects). This is making my install file very large, and I need to cut it down.
If I take just the parts of the library I am actually using, is there any way to find out which of the other JAR files are still being used? It seems that a missing JAR at runtime might not be detected when the program runs up (is that correct?) but might result in a runtime error later on when Java tries to load the library.
Is there a more methodical way of doing this than just removing various JARs and checking if it still works?

Run app with -verbose:class - you can do this standalone or add parameter to JRE in the Java Control Panel
(also enable tracing and then check result trace file).
This option will list where each class is loaded from.

Sparc Soalris patch upgrade - which patches are needed ? (newbie)

showrev gives :
SunOS 5.10 Generic_127111-10
I want to know if I need to install some patches (I am using this host as a high performance J2EE server)
On http://sunsolve.sun.com/show.do?target=patchpage I type in 127111-10 and do find the patch and I read ...
Summary: Obsoleted by: 127111-11 SunOS 5.10: kernel patch
Then I search for that patch and I read it is also obsolete etc
Surely there is a simple way for me to type in "127111-10" and read what exactly I should install.

It's usually a good idea to install the current "Solaris 10_xxx Recommended Patch Cluster" every couple of months.
Download from sunsolve: (800MB)
Unpack
Read Install Instructions, which usually say:
Bring server to single-user mode and run ./install_cluster
this installs all patches that are not already installed and fit to your installation automatically (can take 1-2 hours)
In your case also install current "J2SE Solaris 10_xxxx Recommended Patch Cluster", which keeps all the java stuff patched.
Installing a single patch mostly painfull, because there are always dependencies, which have to met (see patch Readme)
Use this only in case of particular troubles.

How do I know which plugins are needed

Mozilla's newsletter has just prompted me to check my Firefox plugins. It found five that were up-to-date, all of which I recognise - sort of. I was surprised though that it found another 10 which it said were "unknown" and prompted me to "research". Some of these were pretty blue-chip, like McAfee SecurityCenter, and Google Update - some don't mean much to me. Four are "Real"Something.
I guess I should get rid of those I don't need. My problem is - how do I know what I need? If I disable RealJukeBox, am I likely to find that something I use suddenly stops working? Clicking "Research" may tell me how to remove a plugin, but does not seem to tell me what it does and what uses it. (I think BBC iPlayer uses RealPlayer, so I probably should not remove that.)

Find the ap in the App Store and tap on it to see more info. There will be a section with minimum system requirements.

Which ports are needed for SAP HANA Studio - HANA DB communication?

I want to connect SAP HANA Studio to a HANA instance. The HANA instance number is 40.
The SAP note 1592925 states that the ports 5$$13/5$$14 and 3$$15 should be open to allow communication between the HANA Studio and the HANA database. I even see the instance in the HANA Studio, but I cannot administrate it and the HANA studio gives this general "I don't want you to know what the error actually is" message:

Do I need to open any other ports to make HANA Studio work with HANA DB?
Regards,
Mark

Hi Mark,
The HANA Studio connects to HANA DB Instance with JDBC on port 3<Instance number>15.
For your HDB with Instance Number 40, the port would be 34015.
HANA Studio will automatically assign the JDBC port number when you assign the instance number when you add new system.
Looking at the error message that you posted:
!ENTRY com.sap.ndb.studio.navigator 4 1 2012-01-16 14:01:40.627
!MESSAGE [HDB hostname 40 (SYSTEM)] Error on refreshing system
It looks like the hostname entry was not entered correctly (you might have entered "hostname" value when adding the system in HANA Studio).
Here is an example of correct log entry on DCA database instance on hanasvr-01 server with Instance number 00:
!ENTRY com.sap.ndb.studio.navigator 4 1 2012-01-10 13:55:23.598
!MESSAGE [DCA hanasvr-01 00 (SYSTEM)]
You may want to delete and re-add your HDB instance in your HANA Studio.

Ferry

How many portal roles are needed for multi-country ESS?

we are implementing ESS for multiple countries.
has anybody tried to use one portal role for all countries?
the new ESS business package comes with one ESS portal role that has content for all countries. I was wondering if we can use this role as-is (after making a copy of course) to present content for all countries, instead of creating one portal role for each country.
Regards,
Tiberiu

in Employee Self-Service > General Settings > Homepage for Self-Services > Resources> Define Resources
did you have to enter the PCD path to the country-specific iView?
In that path you associate any resource to a Portal Page. Just change the PCD Path for custom Pages only.
Only the services are "country-specific" (because they have assigned a MOLGA). Follow the path from my previous answer to add any country-specific app.
the standard installation does not have the PCD path populated, it has the name WebDynpro application component instead
This is common issue. Depending on how the installation/upgrade was performed, the resources table is populated or not. But if is not populated, the "URLof PCD Page" property is taken from client 000. In my last implementation, i expected this issue, but i not populate manually this property and everything works fine.
Kind regards

Which packages are needed for rt73 chipset?

Right, so the last time I installed Arch, I blindly installed every package related to networking and the size of the install came out to be quite big for an arch install. This time, I want to reinstall it with the barest amount of packages needed for me to get on the Internet (including base and base-devel), so which packages do I select?

While I have no first hand experience of rt73/rt2571 based devices myself, the Arch Wiki suggests it's no big deal.
I use wicd as a wireless connection manager as it comes with a curses based interface so you can easily select wireless networks before setting up X.org (or if you don't use it). It is very easy to set up and manage.

Which plugins are needed/ good for firefox?

I have several plugins listed that are followed by (?Research) what does this mean?

Can you guide me on how to change it to adobe reader as the default. I can't figure out where this option is.
I have to get access to the computer with the probloem to pull up the error message when trying to open a pdf file in Explorer. I think it says that it can`t find the program or to try shutting adobe down and try again.

Which BADIs are available for call list maintenance

Hi
I have created a call list after campaign execution. In the call list maintenance I have to set a few parameters. I was wondering if this could be automated by way of a BADI implementation. For example we would like to assign the call list to the appropriate org unit, interaction center and for the call list to be activated automatically rather then having to be done so manually.
Cheers
Declan

There is no BADI exists for this functionality. You have write your own FM and include your custom FM at the beginnin of this BADI: CRM_MKT_MODIFY_ORDER. The main import par is GUID of Campaign
Also check this note: 1064578
Let me know
Hope this helps

Which privileges are needed to create workspace for using existing schema

Hi,
until now I always created new workspaces creating new schemas.
today I decided to use existing schemas. i created an user (default tablespace "users", with a lot of privileges (create any context, create table, etc..)
i tried to create a workspace.
now i got an error: no sufficient privileges for tablespace "users".
how to solve ?
Leo

Leo, you might try altering your site preferences using the apex_admin app so that it doesn't try to install the sample/demo applications during workspace creation. Then repeat the provisioning attempt. If it works, then you'll know the error had something to do with sample/demo app creation in the schema. If it still gives you an error we'll know that too.
