1 Introduc tion – Collaboration Folders (cFolders)SAP Product Lifecycle Management (SAP PLM) contains a Web-based cooperation platform, referredto as the Collaboration Folders (cFolders), which is dedicated to promoting communication andcollaboration between groups of people who need to work together but are regionally dispersed.cFolders work by enabling teams to set up joint virtual work areas on the Internet in which they canexchange information based on a structured format. This approach not only saves on costly travel

expenses, but also improves data consistency and reduces project runtimes significantly. Other keybenefits for the company as a whole are:Shorter lead times in all project phases, leading to reduced time-to-marketHigher-quality productsLower product development costsLess unnecessary repetition of processes in product development

With the needs of a broad range of industry sectors in mind, the cFolders in SAP PLM offer twoscenarios. The Collaboration Scenario supports cooperation between all the internal and externalpeople involved in product development in a single joint work area, while the Competitive Scenario letsyou set up separate areas for rival suppliers taking part in a competitive bidding procedure. It is alsopossible to connect the cFolders in SAP PLM to end-to-end e-sourcing processes, such as those

provided by SRM. All that is needed to access the cFolders is an Internet browser: A system of authorizations controlsaccess to the individual work areas, sub-projects and documents. When project team members wishto work on specific documents, they either access them directly in the work area or t ransfer them fromtheir local computer or from the Document Management System (DMS) in SAP PLM into thecollaboration area. Documents can be subjected to version management and locked for other userswhile they are being processed.

Catering specifically for engineering and design tasks, the cFolders provide an integrated user interface (EAI Viewer) that supports mark-ups and redlining in 2D and 3D CAD drawings. There is alsoa notification service that project team members can use to find out about any changes made at either project or document level. This function really comes into its own in cases where team members worklocally, and rarely or never meet physically to discuss aspects of their joint development work.

cFolders offers also an easy-to-use tool to control the collaboration process. On status change

according to a predefined status scheme notifications can be sent and authorizations can be changedautomatically.

The most effective approaches to collaboration are those that keep a firm grip on time-critical phases.The cFolders therefore provide direct access to the WebEx online meeting tool, which gives a forum inwhich to clarify any open questions about documents on screen – without wasting precious time. It i spossible to make applications, documents, and drawings available to all the team memberssimultaneously so that they can work on them jointly.

Formalized data sheets take all the hassle out of structuring technical data such as that required for product specifications. You can base the structure on imported classification systems such as the SAPR/3 Classification System or eCl@ss 1. Alongside documents and data sheets, the cFolders let youdefine bookmarks, discussions, and notes as object types.Furthermore with the cFolders generic objects the customer is able to build his own custom-definedobjects without having to modify his cFolders system.

1 eCl@ss is a standard for material classifications and material groups (including services)

1.1 Purpose and Assignment to the Process/ScenarioThe aim of SAP PLM cFolders is to:

Provide a collaboration platform for setting up virtual teams (incl. external partners) who worktogether in cross-enterprise processes (main focus; design collaboration scenario)Enable partners, suppliers, distributors to create SAP PLM objects (documents, materials, BOMs)without having direct access to an ECC system.

To offer the possibility to publish any backend object to cFolders with custom-defined objects(generic objects)Provide a collaboration tool, which is tightly integrated into the SAP PLM Development Projects(cProjects) application, SRM, CRM, SAP Enterprise Portals and SAP Collaboration for EP and theMicrosoft Windows Explorer.Provide a collaboration platform with maximum security by supporting file encryption on cFoldersserver

1.2 Process Flow1. Project definition:

The project leader:

- Creates a new project with folder structure and objects- Assigns the team members

- Assigns authorizations for objects (documents, folders, collaborations) to team members

- Compares data sheets- Exports and imports objects (document, material, BOM and other custom-defined objects)

from the ECC backend system or Microsoft Windows Explorer

- Creates scheme for status management

2. Project executionThe project member:

- Creates new objects (folder, document, material, BOM, data sheet, custom-defined objects)-

Changes existing object (and creates new version)- Adds a redlining layer on a drawing

- Sends notifications to team members- Invites to online meeting

- Subscribes to objects

All team members can set up online meetings by using WebEx integration, send notifications to other team members (cross process function).

For more detailed technical information on cFolders, see the PLM Master Guide and the cFoldersconfiguration guide at http://service.sap.com/instguides.

1.3 Archi tecture of cFolderscFolders is based on the SAP Web Application Server. The f igure below shows the involvedcomponents. cFolders is located in the Demilitarized Zone to enable partner access.

1.4 Factors that influence the performanceThe following factors help improve performance and save resources:

- Performance problem at display of ‘Collaboration overview’:

Filter function is recommended to use to reduce the number of collaboration incollaboration overview

Authorization object ‘ACO_SUPER’ should be assigned to exceptional user not to standardusers.

- Customer modification to trigger ECC backend integration out of cFolders:

Customer should not use system to trigger ECC Backend integration out of cFolders whichleads to HTTP connection error due to the possible long runtime.

- High number of large documents lead to bad performance:

For high number of large document content server should be used. It is not possible to usecontent server assigned to SAP PLM DMS because of security reasons.

For long term or permanent storage of documents SAP PLM DMS together withclassification should be used. cFolders should not be used as substitute of SAP PLM DMS.

2 Sizing Fundamentals and TerminologySAP provides general sizing information on the SAP Service Marketplace. For the purpose of thisguide, we assume that you are familiar with sizing fundamentals. You can find more information athttp://service.sap.com/sizing Sizing General Sizing Procedures .

This section explains the most important sizing terms, as these terms are used extensively in thisdocument.

SizingSizing means determining the hardware requirements of an SAP application, such as the networkbandwidth, physical memory, CPU processing power, and I/O capacity. The size of the hardware anddatabase is influenced by both business aspects and technological aspects. This means that thenumber of users using the various application components and the data load they put on the server must be taken into account.

BenchmarkingSizing information can be determined using SAP Standard Application Benchmarks and scalabilitytests ( www.sap.com/benchmark). Released for technology partners, benchmarks provide basic sizingrecommendations to customers by placing a substantial load upon a system during the testing of newhardware, system software components, and relational database management systems (RDBMS). Allperformance data relevant to the system, user, and business applications are monitored during abenchmark run and can be used to compare platforms.

SAPSThe SAP Application Performance Standard (SAPS) is a hardware-independent unit that describes theperformance of a system configuration in the SAP environment. It i s derived from the Sales andDistribution (SD) Benchmark, where 100 SAPS is defined as the computing power to handle 2,000fully business processed order line items per hour. (For more information about SAPS, seehttp://www.sap.com/benchmark SAPS).

Initial SizingInitial sizing refers to the sizing approach that provides statements about platform-independentrequirements of the hardware resources necessary for representative, standard delivery SAPapplications. The initial sizing guidelines assume optimal system parameter settings, standard

business scenarios, and so on.Expert SizingThis term refers to a sizing exercise where customer-specific data is being analyzed and used to putmore detail on the sizing result. The main objective is to determine the resource consumption of customized content and applications (not SAP standard delivery) by comprehensive measurements.For more information, see http://service.sap.com/sizing Sizing Guidelines General SizingProcedures Expert Sizing.

Configuration and System LandscapingHardware resource and optimal system configuration greatly depend on the requirements of thecustomer-specific project. This includes the implementation of distribution, security, and highavailability solutions by different approaches using various third-party tools. In the case of highavailability through redundant resources, for example, the final resource requirements must beadjusted accordingly.

There are some "best practices" which may be valid for a specific combination of operating systemand database. To provide guidance, SAP created the NetWeaver configuration guides(http://service.sap.com/instguides SAP NetWeaver ).

3 Initial Sizing for cFolders

3.1 PreconditionsThe sizing focuses on data transfers such as downloading, uploading and copying. Businessoperations such as creating folders, providing authorizations, and status managements have anegligible influence on sizing.

Depending on the configuration, cFolders can store data in the SAP NetWeaver AS database as wellas in the Content Server. In this document, we assume that the data is stored in the SAP NetWeaver

AS.

For sizing the Content Server, see http://service.sap.com/sizing --> sizing guidelines --> solutions &platform.

Memory Sizing Algorithm (for Document Storage in Database) Allocate 4 – 6 GB Memory per core.

Disk Sizing Categories

Assuming the data can be compressed on average by a factor of two you should estimate the number of documents to be stored in the database and their average size. Then the assumption is:

Allocate 10 GB for ECC Server Number of documents * average size of documents / 2For example: 10 GB + 10,000 docs * 1.2 MB / 2 = 16 GB
