Kpro, vaults & content server

Hello all
what is a 'knowledge provider' in simple terms. ?
contrary to a DMS secure storage area (which is always) a SAP database.
so would anyone tell me what is a kpro with an example please.
also what's a 'vault' {other than the obvious}  and a 'content server' ? with an example please.
Thanks

hi,
The SAP Content Server is a separate and server based component to store content such as electronic documents originating from different formats. The SAP Content Server ist provided by development of technology and is to be used cross application for any SAP applications. He is to be installed on a separate system. Typical content is training material and documentation from Knowledge Warehouse or technical drawings originating from mySAP PLM Document Management System.
Kpro n wledge Provider (KPro) is a generic document management infractructure,KPro is the standard document management infrastructure of the SAP Web Application Server, formerly known as the Basis system. KPro offers a wide range of document management functions, such as check-in, check-out, logical hyperlinks, and versioning. The fundamental concepts of KPro are protected by US Patent 6,134,552.
Knowledge Provider (KPro) is the standard document management infrastructure of SAP Web Application Server (formerly known as the Basis system). As such, it is a service which is part of every SAP Web Application Server system.
KPro is a (mostly) invisible service layer that can manage any kind of document. It can be deployed by any SAP application in order to manage and maintain documents and document content in a sophisticated manner.
KPro uses the component SAP Content Server to store document content. In other words, SAP Content Server stores the documents that KPro manages and maintains. SAP Content Server runs on a separate computer that hosts an Internet Information Server (IIS), SAP extensions, and a database (with SAP's DBMS SAP DB). The database is installed as part of SAP Content Server.

  • Kpro usages with common server storage and Content server storage

    Hi Sap Gurus,
    Can any one tell me is KPro tick that we make in Document type if it is related to the storage types we are going to use,
    Can this KPro feature for Document type can be used for any document type irrespective of the Storage type, like weather storage type may be Vault, Archive, SAP DataBase, or the Content Server,
    let me also know waht is the benifits of going for this Kpro Tick in Document type (apart from Storing n no of original files in the DIR)
    we are trying to store original files in acommon Server (not content server) can we avail all the features of Kpro Tick.
    Points awaiting,
    Thanks and regards
    Shanti

    Hi,
    Kpro marked in any of the document type is for indication of using content server as a external storage system.
    Yes, Kpro can be ticked to any document type but since this is related to only external storage device so this wont support storage systems like Sap Database, Vault but supports to Archieve through Archievelink interface.
    Benefits are many and depends upon the business requirement..
    1. all the documents related to the organisation can be storaged in external content server rather thn in SAP database of R/3 system which avoids load on R/3 database.
    2. as you said, n number of files can be attached.
    3. it can be used in terms of attachments in Additional files, product stucture and so on.
    4. if Content sever is used also along with cache server then this main server can be used as a central storage location from where globally users can do transaction of documents without and error and in short time.
    Only Kpro storage provides all the functionality, you will be using common server which will be only accesible for storage purpose but not for the extra functions which Kpro provides..
    hope this helps u..
    Thank You,

  • Migration of documents from a http content server into sap kpro und sap dvs

    hello,
    I want to migrate documents from an http 4.5 content server into the sap knowledge provider (kpro) and in sap dvs with an abap program.

    Where I have to write my url for accessing the document on the content server?In which table?
    What fm´s do I need to create the PHIO´s and LOIO´s?
    Has anyone an idea and hints (like weblinks) to integrate documents from an content server into kpro and sap dvs?

    Hello,
    the private key, where the hash is signed with is stored
    in your AppServer directory $DIR_INSTANCE/sec and is
    called SAPSYS.PSE. Where the PSE is a secude (www.secude.de) specific format which contains the private and the publik key.
    But I guess you won't get the private key, because its private, unless you are the Administror

  • Customizing KPRO for an external Content Server

    Hello !!
    Could you help us about this problem .
    We need to install document's archiving onto a external  Content Server (product Documentum), using KPRO.
    We have customized thus :
    OAC0 : Content Repository = Z1 for DMS ( DocArea) and version 045.
    CSADMIN : We receive the message HTTP command adminContRep (operation configGet) is not possible for Z1 (only as of 0046)  when we validate .
    OACT : (Maintain category) , Z1 is affected to SOFFHTTP .
    SKPR08: Categories for physical doc classes , the category SOFFHTTP is affected to the class SOFFHIO.
    With the transaction CV01N , used to create a FID and to join a document , we receive the following error when we try to archive the document :
    "Error during the archiving of D:\Carte..".
    Nevertheless we can find the joined document onto the server Documentum.
    Do we forget a customizing   ???  Thanks a lot .

    Hello
    i don't know the version of SAP ERP you're using but nevertherless you should bear in mind this detail:
    CSADMIN: "digital signature" not checked means you are not using it.
    OAC0:"No signature" SHOULD be checked if you are not using it (to be consistent with CSADMIN)
    However i am not sure this is solely responsible of your errors; in case of SAP content server, if it works for one user, it will work for the others.
    Please be more clearer in your last part  ???
    Do you mean only the user having done the check-in of the file who can afterwards access the original (in display and change) ?
    what do you mean by "For the other people, it doesn't find the original location" and also by "unless we create the same original location, or we change the original location".
    In case of SAP Content Server, we don't care about "location", whether the file comes initially from a fileserver X or Y or Z, as far as the file has been correctly checked-in the content server, it should be accessible for anybody (as far as user rights allow it)

    Hi all,
    Is it a mean to get directly in KPRO the number of files (and eventually the size) contained in a KPRO content server?
    Do you know any KPRO/CCMS tool to perform this?

    Hi David,
    there might also be people around here (Java-based EP-KM) who know this (I do not). But you may also want to try an ABAP forum...

  • SAP Easy DMS / KPRO / Content Server

    Dear Fiends,
    We have a requirement to configure the SAP Easy DMS integrating with ECC 6.0 EhP6 application. I am trying to understand the base application components which are needed to set-up the landscape.
    My questions are:
    1 - Do we need SAP Content Server as part of the SAP Easy DMS configuration to store the attachments? (or) Can we use shared file system and link it to SAP Easy Document Management directly to store the attachments?
    2 - Do we also need KPRO along with SAP Easy DMS?
    Thank you,
    Sri

    Hello Tilak,
    Thank you for the response.
    Based on your comment, We have to use KPRO regardless whether we use Content Server or not with Easy DMS.
    Is KPRO a additional installation or is it part of standard SAP application and available via transaction codes?
    Thank you,
    Sri

  • Aletar KPRO para SAP Content Server (DMS)

    Pessoal,
    alguem já configurou o GRC para gravar no content server da SAP ?
    Obrigado,
    Marco

    Zerbini,
    vc está querendo utilizar um outro content repository com o GRC, que nao ou standard NFE_COR_DOC_REP, ou mesmo modificar esse content repository pra usar algum outro content server que nao a tabela /XNFE/CORCONT?
    O NFE standard é feito pra trabalhar apenas com o content repository local. Note que nas chamadas do KPRO (function modules /XNFE/CORE_KPRO_XML_SAVE & /XNFE/CORE_KPRO_XML_READ) sao todas feitas sincronamente sem tratamento de erro de comunicacao. Em caso de erro, ele simplesmente dá um raise em alguma exception. Ou seja, se você alterasse o content repository standard pra apontar pra um content server externo, no caso de a SEFAZ te devolver o protocolo de autorização e a comunicacao com o content server falhar, vc teria simplesmente um raise da exception sendo jogado pro proxy, ou seja, um dump "na cara". Não teria restart amigável pelo monitor nem nada.
    Talvez seja uma feature request a se solicitar ao time de desenvovlimetno do GRC, mas por enquanto, eu nao cosideraria essa opcao de usar um content server externo, simplesmente pelos riscos envolvidos.
    Abs,
    Henrique.

  • Post-actions for Kpro-Content Server after Sap DB Copy

    We have a Sap system based on Web As 6x connected to a Sap Content Server to store originals.
    We copied back this Sap system to the quality system.
    Now the Sap quality environment refers to the same Content Repository of the production, and we want to modify this.
    From this environment it should not be possible to access or to modify the originals of the production.
    More in general, wich post-actions can be done on the Sap target system after a DB copy where the source system is connected to a Content Server ?
    For example, which tables can be cleaned up ?

        After installation i got the message that everything is ok.But then when i execute the command
    http://<server>:<port>/ContentServer/ContentServer.dll?serverInfo
        I get the response as page cannot be displayed.I want to use the content server for DMS storage so that i can use KPro instead of the vault.
        Same thing when i do

        I get a pop-up asking for the user-name and password but when i give the user name as administrator and password it doesnt allow access.
        Please advise
    Regards

    Note Number : 361123
    Symptom
    You want the SAP Content server to work properly.
    Other terms
    Signed URLs, AdminSecurity, SsfVerify failed
    Reason and Prerequisites
    The SAP Content Server was installed in accordance with the installation guide. For new installations, we recommend that you use the latest released version of the SAP Content Server, regardless of the SAP System release to which the SAP Content Server is connected.
    Solution
    This note provides additional information on different aspects of security when using the SAP Content Server.
    Security against data loss
    •     The SAP server content stores the contents of the confidential document either in an SAP-DB instance or in the file system. To avoid data loss, the usual measures for databases and file systems are taken. These are only mentioned briefly here: Redundant hardware (mirror disks, raid systems and so on), regular backup (log files, backup). When you back-up the Content Server, note that you also have to save the ContentServer.ini configuration file as well as the Security directory in addition to backing up the database instance or the directories of the file system used for document content.
    •     Note 319332 describes backup strategies for a Content Server with database folders.
    •     SAP does not have a tool for backing up file system folders. In this case it is the responsibility of the customer to select and convert the backup strategy. Here you should note that, for a complete and consistent backup of a file system folder, it may be necessary to shut down the Content Server for the duration of the backup.
    Security against unauthorized accesses on filed contents
    •     Before you access the content server, an authorization check usually occurs in the SAP system. However, the content server is usually accessed using a disclosed HTTP log. To make sure that only authorized accesses are possible, 'signed URLs' must be used. Signed URLs are URLs that were signed by the SAP system. You can recognize signed URLs because they are considerably longer than unsigned URLs and contain additional parameters. The signed URL, in particular, contains the additional parameters expiration (expiry time) and secKey (digital signature). A signed URL is only valid if the expiry time has not yet been exceeded and if it contains a valid signature. In order that the signature can be checked by the content server, the public key (certificate) of the SAP system must be stored on the content server and tagged for the corresponding repository. Transactions OAHT, OAC0 (as of 4.6C) and CSADMIN (as of 4.6C for SAP content server) are used to transfer the certificate. The certificate must be activated on the content server for the repository. Use CSADMIN to do this (for SAP Content server).
    •     In order that the digital signature of the SAP system can be used properly, EVERY SAP system must have its own unique certificate. To ensure this, a 'PSE' must be generated once in every SAP system after this SAP system is developed. Use transaction PSEMAINT to do this (note 354819).
    •     To protect the connection between the Content Server and its SAP-DB instance, the name and password of the database user can be changed and stored in encrypted format in the configuration of the content server. For details, see note 661852.
    Access control for the administration
    •     The content server is partly administered from within the SAP system, and partly from outside it. When it is administered from outside, you must ensure that only authorized persons have (administrative) access to the server on which the content server is running. The (administrative) access to the database (note 212394) must be restricted accordingly.
    •     In order that administrative accesses from the SAP system are only possible for authorized persons, the parameter AdminSecurity must be set to 1 in the content server. You will find details on this in the installation documentation of the SAP Content Server.
    Protection against server hardware outage
    •     The Windows version of the SAP Content Server can also be installed in an MSCS environment (Microsoft Cluster Server). For more detailed information, see "SAP Content Server 6.20 in an MSCS Environment", dated March 4, 2003, in the "News" section on the SAP Service Marketplace (http://service.sap.com/ha
    •     The duration of the non-availability of content servers, cache servers and alias servers can be reduced with the automated operator intervention described in note 484459.

  • Migrate the document from database to Content Server

    Dear All;
    There is a ECC6 using for 5 years and I am setting up a External Content Server which link to this ECC6 server, from now on the new incoming documents like scanned document, email etc will save to Content Server. 
    However, for the past 5 years those old incoming documents that save in the ECC database, how can l migrate it to Content Server?  In the past the document mostly save with GOS (generic object service) option.
    Please advise.
    Thanks
    Jordan

    Hi Jordan,
    from DMS point of view I would recommend you to see the reports DMS_KPRO_CONVERT and DMS_KPRO_CONVERT2 which can be used to transfer original files from older storage to KPRO storage logic.
    If you want to move the originals from an archive or vault to a Content
    Server, please use the DMS_KPRO_CONVERT and DMS_KPRO_CONVERT2 report I 
    would kindly ask you to see teh documentation on DMS_KPRO_CONVERT report
    in transaction SE38, which explains the whole process and gives        
    necessary information.                                                                               
    This conversion program offers two possibilites:                                                                               
    - Complete migration:                                                  
    The meta data of the document info record and the checked-in original  
    application files are migrated together. The checked-in original       
    application files are transported into the storage catgories.                                                                               
    - Step-by-step migration:                                              
    In the first step meta data is migrated. The original application files
    remain in the old storage data. The migration of original application  
    files starts after you have processed the files with the integrated    
    viewer and checked them into a secure storage area.                                                                               
    I hope this information could be useful for you. Further I would       
    really recommend you to get in touch with your local consulting        
    organisation because this is a very critical and individual process.   
    To grant that the whole migration is done correctly I can only advise  
    you to contact your local consulting organisation.                     
    Best regards,
    Christoph

  • Content server pros and cons when compared to others

    Hi DMS Gurus,
    we are in a process of deciding which storage area to go for, and the client is kneen on going for a common existing  server, as he is not kneen on spending on DMS content server.
    my question are,
    can we transform any existing file server or system (which is already in use) in to a content server just by installing windows 2003, and content server CDs. if so please tell me how to go about this.
    is content server only the preferred storage to process the original files in through WEB DMS, or will Starage in SAP Database,Vault or Archive also will give this funtionality.
    let me please know what are the major Pros (benifits) and cons (demerits)  which Content server storage gives when compared to other storage.
    Points for sure,
    thanks in advance
    Shanti

    Shanti,
    ArchiveLink:
    You use SAP ArchiveLink as a communication interface between the document management system and the archiving systems. You can display the archived data using the SAP ArchiveLink viewer. Many times there are documents generated which needs to be tied to a DIR and hence you use the archive link to tie these to a transaction and the originals can be stored in the content server.
    KPRO
    KPRO apart from attaching the originals, it provides a wide range of other functionalities like content service,
    where after every check in& checkout of DIR you can mantain the working copies in the content server.
    Knowledge Provider is a component of SAP Web Application Server and provides the general infrastructure for storing and administrating documents.The Content Server and the Cache Server are server components that interact with the Knowledge Provider
    Knowledge Provider provides the following services:
    -Services for KPro client applications
    -Document Management Framework (DMF)
    -Document Management Service (DMS)
    -Content Management Service (CMS)
    -Integration of content servers and cache servers
    -Content Server
    -Allows you to integrate SAP Content Sever or
    external content servers
    -Cache Server
    -Allows you to store documents close to the client (caching)
    -Content Modeling Tool
    -Document Modeling Workbench (DMWB)
    Hope this helps

  • Latest version of Content Server

    Hi All
    I need some assitance in understanding what the latest version of the Content Server is. I know 640 is probably the one, but what confuses me is the content Server Service on SICF on the ERP system for example. Now, does that mean the content server is integrated to the system or do we still need to install a stand alone Content Server.  What other way can we implment DMS without the use of the content server, i.e. can the portal knowlege Management achieve the same? if so, what are the prerequisites and pros and cons?
    Thanks
    Ronny

    Response to your second question: Portal Knowledge Management is a stripped down version of DMS. It provides basic content management features with embedded asynchronous and synchronous collaboration(review,rating,feedback,discussion etc).
    SAP DMS (with content,cache server setup) typically cater to a long term Document Management strategy involving designs, drawings, technical specifications etc with rich features like Markup and redlining,Document life cycle definition, Distribution strategies, Digital signature, SAP R/3 Object linking,CAD integration etc. The storage options in SAP DMS are:
    1. 'DMS Storage' option(may store in SAP DB,Vault,RFC Archive), you can store upto 2 originals/documents and 99 additional files.
    2. 'kPro Storage' option(may store in SAP DB,HTTP Content Server), you can store 'n' originals/documents and 'n' additional files
    NOTE:
    HTTP content server
    Either the SAP Content Server or a third-party content server can be used.
    SAP database
    If you want to store your documents in the SAP database, you need a content table. All your documents are stored in this table in the SAP database. The content table can be cross-client or client-specific.
    RFC storage system
    RFC is used for storing documents in the context of SAP ArchiveLink, the Archive Development Kit (ADK), or an application that uses SAP ArchiveLink or the ADK.
    Logical repositoryThis storage type allows access to different physical repositories, independently of the client and the system ID.
    Structure repositoryThe structure repository is only used in the SAP Knowledge Warehouse environment.
    The content server is available for free on SAP marketplace for exisiting SAP customers. This needs to be setup on a separate hardware(specifications can be arrived at after contentserver sizing). The storage limit using content server can be scaled upto 50+ terabytes of data.
