One Portal for ESS - multiple HCM backends?

Hi all,
I am wondering if I could run a portal (7.00) and connect this to a HCM backend with ECC 6 EhP2, thus requiring the BPs and content with WebDynpro/Java technology to be deployed in the portal and simultaneously connect to another HCM backend based on ECC6 EhP5, thus requiring the necessary BPs and content with WebDynpro/ABAP technology in the portal (by the way: which BPs are necessary to be deployed in the portal?). For accessing services in the EhP2 backend we will use the Homepage framework but for accessing services from the EhP5 backend we will use only WebDynpro/ABAP. Can we use both of them in one portal (of course by means of different roles...)?
Kind regards and thanks in advance for any hints,
Uwe

Yes, this is possible.
by the way: which BPs are necessary to be deployed in the portal?
EhP2 requires a BP ESS 1.2 and EhP5 needs BP ESS 1.5
Can we use both of them in one portal (of course by means of different roles...)?
Yes, you may as long as you are able to make sure that there would be two similar set of PCD objects existing in your scenario and you dont mix them up

Creative Cloud - One ID for my Multiple Laptops?

i am looking into buying Creative Cloud for Photoshop and Lightroom, however I work on multiple desktops. Can one user ID enable me to log into my work on multiple desktops? Also, does the Photoshop cloud have the same functionality and the stand-alone?

You can have multiple installations of the software but it can only be activated on two machines. You can only use one of the two machines at any given time.
I do not know if some functionality was removed from Photoshop prior to creating the Cloud version(s), but theoretically, the Cloud version will have the newest functionalities while the standalone will not gain any new features.

Setting Up the System Landscape for ESS

Hello Experts,
I am implementing ESS in portal.
I am in step of defining systems in portal for ESS/MSS.
Below is link I am following from help.sap.com
[Link|http://help.sap.com/erp2005_ehp_04/helpdata/en/5b/76a6d7fd3a4e91bfb422405bf3e04d/frameset.htm]
In above link it is mentioned that we have to define following systems :
SAP_WebDynpro_XSS
SAP_ECC_HumanResources
SAP_ECC_Travel
SAP_ITS_XSS
SAP_BSP_EREC
Additionaly according to below Article in SDN :
[Link|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/21eb036a-0a01-0010-25a3-b2224432640a?quicklink=index&overridelayout=true]
Following additional systems must be created :
SAP_ITS_EBU Looks similar to SAP_ITS_XSS above
SAP_R3_Financials
Now the basis person in my project has handed over to me following systems :
SAP_BSP_EREC
SAP_ITS_FND Name mismatch as FND is used in place of XSS or EBU
SAP_R3_Financials
SAP_WebDynpro_ESS Name mismatch as ESS is used in place of XSS
Now below two systems are altogether missing as per first link on help.sap.com
SAP_ECC_HumanResources
SAP_ECC_Travel
Please explain if it requires to be corrected or name mismatch and missing ststems would do.
Thanking you in anticipation.

All the above names that you are referring to are not necessarily separate systems.
These are system aliases for a system object created in your portal via System Administration - System landscape.
So, if you have HR and Finance on the same backend server, then you need only one system with the related system aliases.
You will need SAP_BSP_EREC only if you are planning on using E-recruitment.
Similarly, you will need SAP_ITS_XSS only if you are planning on using any ITS applications.
It is pretty straight forward to change/correct the names of your system aliases instead of changing the usage of these aliases every where else.
SAP_ECC_HumanResources is absolutely necessary.
SAP_ECC_Travel is required if you are planning on using travel and expense related applications.
Also, note that SAP_WebDynpro_XSS should be the alias of the system where your webdynpro applications are deployed (typically the same portal server)

Multiple ESS's in one Portal connected to different backend systems?

Hi,
We have two backend systems installed.
We have one portal.
We want to create a second copy of the ESS Portal content connected to the the second backend.
Datawise this is not a problem.
But what about the JCo's and the Homepage Framework?
The WebDympro application seems to look for two specific JCo (for example SAP_R3_HumanResources and ...MetaData) and then both copies of ESS want to use this. Is it not possible to have each copy of ESS use it own JCo's and connect to its own backend system for the Homepage Frameworks?
Thanks,
Adriaan

Adriaan,
Its NOT possible to even talk to different clients in same backend system because you cannot duplicate the JCos and while creating them you need to specify the system and client details.
Also it uses a system alias which also has to be unique.
Per my knowledge one portal instance can talk to only backend client and to talk to another backend / client you will need to create a new instance within the Portal.
This [help|http://help.sap.com/saphelp_nw2004s/helpdata/en/82/76a2406546ba15e10000000a1550b0/frameset.htm] talks sometihng on multiple backend support. I am not much aware about it but see if it helps you.

Backend R/3 connectivity for ESS MSS from portal

Hi,
We are currently in development cycle for ESS/MSS based on portal EP 6.0 SP16 and ERP 2004 in backend. We are trying to find out how the ESS/MSS business package on portal works with backend ESS functionality in ERP 2004. It is more of a connectivity question. We want to know if we expose our portal to internet so that users can login to ESS/MSS from internet, do we need to put backend ERP (ECC 5.0) system also in DMZ? Do we need to open ports between portal and R/3 so that ESS/MSS can work? Or the communication happens using JCO connections and we need not to expose R/3 system.
Also one more specific question? If someone knows how ESS/MSS talks to backend system. At SAP application layer level or database level? I am asking this question to check if I need to open a port to talk to database or I can very well keep 2-3 SAP application server in DMZ and work.
PK

You need to look at the specific business package. For example, ESS for mySAP ERP 2004 says that the technology is Java / Web dynpro, which says that the Java engine uses RFCc to get the data from the backend.
Othe businesss packages may use ITS, which then needs another connection from the user to the ITS server.

One portal instance for multiple hostnames with one of them using SSL

Hi,
Is it possible to use one Portal and Login Server instance for managing two hostnames (like www.site1.com and www.site2.com) of which one is using SSL. If yes, how do I do this? What do I need to configure?

There are procedures on the configuration guide under virtual

Mapping of single Portal users to multiple backend user

Hello Experts,
It is possible to map single portal user to the multiple R/3 user? If yes, than what is procedure to achieve it?
I have a SAP Portal where some users have 2 user ID in ECC, but I need to in Portal the users have only one user ID and password. How can I do to these users can select between their 2 profiles in ECC? Is posible?
Thanks!
Regards

Hi,
This is not possible since you would have used SSO to connect to the Backend. Either it is SSO or User Mapping is done, Portal User can only access the Backend with one User ID.
If you use SSO, for Example if the Portal User is UserA then you would have the UserA in the Backend too. It will use the UserA in backend to access. (Note: Single User can't access multiple Backend. Since we would have already maintained the Backend Connection details in the System and also in JCo Destination. So it is not possible for a User to access the Backend with two different Backends)
If you use User Mapping, then you can decide the User which it should use. (For ESS/MSS this is not recommended and it is not feasible too).

Implementing SAP EP as a Central Portal for mulitple R/3 ECC Backends

Hello
We are trying to implement an Incident / Occurrence Management Solution for a Company with 6 different subsidiaries who run their own SAP ECC Backends which are geographically located in different parts of the country.
The idea is to implement a central SAP Enterprise Portal for these different subsidiaries and we would like to know if anyone has done anything similar before. So the idea is that anyone from these 6 different geographically locations can log an incident on the central portal and the data will be then updated on their own divisional ECC Backend.
Currently the SAP ECC Backends are based on ERP2005.
The Company itself has an Central Active Directory solution in place and single sign on could be used for authentication. All the subsidiaries already use the central Active Directory for authentication.
Could anyone please let us know whether they have done something similar or have any reasons why this cannot be done and some potential issues that could arise for implementing a solution like this.
Some potential issues could be:
System aliasing
Network connectivity, bandwidth, availability issues
Patch alignment etc
Would there be other issues that one would consider?
Thank you kindly.

Hi,
I dont see any issues with such a landscape. You can have content for each of this location based of the systems they access.
As u have said bandwidth, network issues and roles assignment would be concerns as they would be in a single ecc backend connected portal

One Portal - multiple URl's, orgs, groups

Hi Forum
I am in the process of doing a proof of concept for using Web Space Server to manage a large spectrum of diverse communities, hosted within a single portal. One could describe this as a large virtual organisation.
The basic requirements are roughly the following:
1. The portal will serve multiple small organisations and interest groups, with each org or interest group having its own landing page.
2. Each landing page will have its own unique URL i.e. myspot1.com, myspot2.com etc. and the web server need to redirect each URL to its appropriate landing page.
3. The look and feel of each landing page will likely be unique in terms layout etc. thus need to be customised for each instance.
4. Web Space will be used in conjunction with Glassfishv2.1 and MySQL. The server will also run the amp stack with Apache on port 80 for other purposes.
5. This portal will serve as a core foundation shared amongst various organisations, groups etc to enable collaboration across organisational and community boundaries with least effort form a user perspective to engage wherever need to.
From playing around with both Liferay and Sun Webspace Server, it seems that these platforms can serve as a core to manage access rights, permissions, organisations, groups, etc.
My immediate needs are to better understand the following:
1. What is the best practice to route URL's to its unique landing page prior to client login?
2. From a webserver perspective, what are the options to route URL requests to the appropriate Web Space "entry points" i.e. would one set this up in Apache, Glassfish, or Web Space and how?
3. What are the options to customise each landing page to have its own unique look and feel?
Any comments or pointers to documentation will be greatly appreciated.

1. What is the best practice to route URL's to its unique landing page prior to client login?What you need is virtual hosting.
See http://www.liferay.com/web/guest/community/wiki/-/wiki/Main/High%20Availability%20Guide#section-High+Availability+Guide-TheBigPicture for details.
2. From a webserver perspective, what are the options to route URL requests to the appropriate Web Space "entry points" i.e. would one set this up in Apache, Glassfish, or Web Space and how?See my first comment. It can be handled in the web server(tomcat)
3. What are the options to customise each landing page to have its own unique look and feel?Each community can have its own look and feel.
See http://docs.sun.com/app/docs/doc/820-7054/ghycy?a=view to know how to do this.

For ESS which one is better ? (Webdynpro for Java or Webdynpro for ABAP)

For developing Employee Self Service(ESS) which one is preffered Is webdynpro for java and webdynpro for ABAP ? Why ?
What are the differences ?? Please give me clearly.
Thanks
Risha

Hello Olivier ,
Thank you for gvg quick reply.
For dessert which one is preferred : apple pie or chocolate pudding ? - I am not able to decide
Actually I have requirement for developing ESS in Portal. I am new to ESS and heard presently using WDA for ESS.
I did't get reasons why using WDA. basically I am from WD for Java.
If possible give me differences.

Do we need to install SAP Portal for implementation of ESS & MSS

Hi All,
We are implementing SAP (ECC 6.0) for one of our client, Due to some contractual limitations, we do not want to implement SAP portal though it is a part of standard delivery, I want to know that is it absolutely necessary to install and implement SAP portal for implementation of ESS & MSS.
What i know and understand is that with the new architecture ESS & MSS can be deployed and accessed as a stand alone application on an internet browser by (Web dynpro client) without any need of enterprise portal. While ESS & MSS application can be hosted on Web application server.
Please validate my understanding if it is correct, Also does the new Web dynpro based client support all the functionality and authorization related issues for ESS & MSS ??
Regards
Amit Ajmera

Hi Amit,
Yes, you can run ESS/MSS as WebDynpro application without having to deploy on Portal. However, the look and feel and user accessibility is much better when deployed as Portal page. For WebDynpro, you will still need to publish the individual URL link to application somewhere...
Another point is that on portal you can deploy standard Business package specific to ESS and MSS which contains lots of readymade iviews/page/roles etc so it can reduce your development cost dramatically.
But, at the end it all depends on your individual requirement and project scope.
Cheers !!
Satya.

One Portal Multiple BI systems

Hi,
I have a scenario wherein there are two BI systems and one portal that is used for displaying the data. Now I know we need a BI JAVA on the portal for this scenario.
My doubts are:
1. Can we use BI JAVA to connect and pull data from multiple BI systems?
2. Is SSO essential for the running of BI JAVA? If yes then how can i connect two BI systems to one portal with SSO.
Federated Portal is NOT to be used. Any other pointers in connecting 2 BI systems to a single portal and use the BI JAVA functionality is welcome.
Correct answers will be suitable rewarded.
Thanks,
Arun E V

Your approach is very interesting and I'd like to comment why FPN might be your best option in this case.
If you are running new 7.0 web functionalties each BI 7.0 system must have usage types:
ABAP side: AS ABAP and BI
JAVA side: AS JAVA, BI JAVA, BI EP
See: https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/d0606dd7-011d-2a10-e1a8-d66b35bb0767
If in your case you would like "federate" your users (and subsequently the content for those users..roles, iViews, etc) across several BI systems then having an overall EP ("corporate portal") using FPN would be the best option.
Now, If you have two seperate BI systems (with a BI Portal on each) the only way your users can switch from one BI to the next is via SSO, however you are still logging into each BI system and have to maintain portal content (user roles, iviews, etc) on two seperate systems. By using FPN can you maintain this all from one single point of access.
