This workshop is part of a series of SAP-related worksh

5、ops which are held by the Department of Production Management of the Vienna University of Economics and Business Administration, headed by Prof. Dr. Alfred Taudes. The workshop was developed by Andreas Mild. The goal of this Project Management Workshop is that, after having attended it, each student

6、 should be familiar with the theoretical backgrounds and be able to plan and control a project. The project manager has the task of ensuring that the project is executed efficiently, on time, and within the budget - which he/she achieves by making certain that the required resources and funds are av

7、ailable when needed. Every student should then be able to put his/her SAP knowledge into action.To make the continuous improvement of this script possible, please report mistakes found or ideas for further development to dwu-wien.ac.at.2 Basics & KeywordsSAP R/3 is an integrated and indus

8、try-independent standard software which covers, integrates and connects all functional areas in a business. SAP AG defines integration as defined communication. AFOS (Hrsg.) SAP Arbeit, Management. Braunschweig/Wiesbaden 1996 p.59 Although R/3 is designed for complete integration, it can also be use

9、d for a couple of business areas. Computerwelt No. 13 of 13. 3. 1998, p. 20 SAP is the abbreviation for “Systeme, Anwendungen, Produkte”, the German words for “Systems, Applications, Products”. AFOS (Hrsg.) SAP Arbeit, Management. Braunschweig/Wiesbaden 1996 p. 59 Information about the company can b

10、e found at: .Projects are tasks with special characteristics. Attributes of a project are the following issues: complexity, non-repetitivity, high risk detailed goals to be achieved time restrictions high cost and capital expenditure quality requirements often strategic significance

11、To be able to plan, monitor, control, and carry out a project as a whole, the project goals must be precisely described and the activities to be performed have to be structured. A project can be described as follows: according to how it is organized, i.e. by explaining the project structure, accordi

12、ng to the processes involved.A project starts out as a statement of work which is either a written description of the objectives to be achieved and the desired rough schedule like start and end dates. In the description one could include also performance metrics and budget constraints.A project is f

13、urther subdivided into meaningful pieces, referred to as tasks. Tasks take usually less than a few months. The task can be further subdivided into subtasks.A work package can be defined as “a group of activities combined to be assignable to a single organizational unit.” Chase R./Aquilano N./Jacobs

14、R. Production and Operations Management: Manufacturing and Services, p.48 The project tasks, subtasks, and work packages are brought into a hierarchy by defining a work breakdown structure.The individual elements represent activities within the work breakdown structure and are called work breakdown

15、structure elements (WBS elements). WBS elements can be: tasks partial tasks which are subdivided further work packagesWBS can be structured according to object function phaseWhich kind of structuring is used depends on the focus of the project. Objects orientation is often used, if the main part of

16、the project is a physical object like a power plant. Functional organisation is preferred, if many different parts of an organisation or many organisations are involved.In practice, all three kinds of structuring are used within one WBS.“Project Management can be defined as planning, directing, and

17、controlling resources (people, equipment, material) to meet the technical, cost and time constraints of the project.” Chase R./Aquilano N./Jacobs R. Production and Operations Management: Manufacturing and Services, p.48 The primary reason why projects fail is insufficient effort in the planning phas

18、e. Chase R./Aquilano N./Jacobs R. Production and Operations Management: Manufacturing and Services p. 69 Project Management thus is considered as very important.The SAP Project System enables close and constant monitoring of all aspects of a project by having constant access to data in all the depar

19、tments involved.Project management can be subdivided into project planning, i.e. the task which will be undertaken before the project starts, and project controlling during the implementation of the project.Planning must include: organization service process dates costs capacityThere are many possib

20、le project goals such as, for example, to realize a positive net present value, to achieve a high imputed interest, to minimize costs, to cover costs, to maximize gross profit, or simply to finish as early as possible. However, it is important, that goals are defined operationally, thait is when it

21、is possible to measure to which extent the goal has been achieved. The project manager breaks the project down into a set of activities. Then he also defines the relationships among these activities. The outcome is a guideline regarding the activities that can be performed in parallel and those that

22、 have to be done in a sequential order. This task is done via planning by network.Now, there are activities that require capacities and resources like personnel and material. Such resources are limited and these requirements have to be considered in order to be able to develop a feasible, sound plan

23、. Information from other modules as e.g. the material planning module is required.The system calculates the material requirements for each step of the project and organizes that materials are bought in time to avoid delays. When purchasing material, the system takes into account order sizes, invento

24、ry policies as well as other information. To prepare the financial statements, the value of work in progress (including project work) has to be calculated. This also requires interaction of some R/3 modules.Thus, the system needs information from all business areas simultaneously. And this is exactl

25、y what integration does.The project module is part of the integrated concept of SAP R/3 providing interfaces to other modules like Accounting, Distribution, Material Management and Production Planning and Control. Each area within the organization has its own structure and its own view of the projec

26、t, but data has to be entered only once.3 Getting ready for the workshop This chapter provides information on the first use of the system. Logging on R/3Logging offSAP R/3 is a client/server application. Therefore, you have to cancel the connection with the server by telling it that you want to log

27、off. Create SessionOften it is useful to open more screens. You can do this by creating a new session, like a new document in a word processor.SAP HelpIf you want to get some basic information about a specific field, focus this field with your mouse and press .The dialog box indicates what the field

28、 is for. Sometimes even dependencies are explained.Match codesMatch codes are useful for finding data, because it is difficult to know/remember the identification number of a line position such as a material.Example:You want to edit the material master of a material. You dont know the number, but yo

29、u know that the material description starts with something like “PM_”If you press F4 you get a search-mask where you are able to search with wildcardsAfter having pressed Enter you get a list with the search results.Then you can select one material, you can sort or cancel. Transaction CodesThe follo

30、wing screen will be often used during the workshop. Thus, we can use Transaction Codes for faster access.Then select Structure planning Change Project.Now, we want to “bookmark” this screen.So, we look up the transaction code.The status dialog box opens:Here we see a lot of information concerning im

31、portant relevant technical details.Wherever you find yourself in the system, you can get to this screen by entering CJ20 in the Transaction screen.Let us refine this a little bit. If you have several transaction codes, you may get confused. Key in the appropriate transaction code and the comment edi

32、t project structure.Then, if you open the combo box of the transaction codes after having entered more codes, you will find the appropriate one .The Standard ToolbarIn many screens you will find the standard toolbar.Save buttonWhen you press the save button, the system also validates your input. If

33、there was an error, you have to correct the error first,before you can proceed.Back buttonIf you click the back button you return to the previous screen without saving your data. HelpEnter buttonWhen you have finished entering information on a screen, you press the Enter button which performs the sa

34、me function as pressing the Enter key.Exit buttonPress it, if you want to leave the current application to go back to the previous menue.Cancel buttonClick on this button to exit the current task without saving. The Cancel button performs the same function as Cancel in the Edit menu.Print button Pag

35、ing keysFind/Find next buttonClick on this button, if you want to perform a search for data required in the screen you are currently working in. 4 Case Study4.1 Case descriptionThis case was developed in order to demonstrate the project system of SAP R/3 . All prices and data are pure fiction and he

36、ld very simple.The object of the project is the specification and installation of an elevator.Physically, the Elevator consists of a cabine an engine mechanical parts a control unitIn the course of the project, these parts must be constructed, procured and assembled.At the end, an external inspectio

37、n of the entire system is prescribed.The project must be finished by 30.6.2000.The company consists of two work centers: Development (PROJ-RD) Installation (PROJ-INS)Specification activities are performed by the Development department. Procurement activities will be done outside the project organisa

38、tion, and neither cost nor capacity considerations are planned within a project for procurement. Installation is done by the Installation department. In particular, the activities are as follows:ActivityDurationWorkWork-centerSpecification of the cabine1020DevelopmentSpecification of the engine1010D

Then, the mechanical parts can be designed. The last activity is the design of the control unit.After th

41、e completion of each specification activity, the procurement of the specific item can be effected.After the procurement of all parts the Installation can start and must be done in two consecutive steps (I + II).The final activity of the project is external inspection.A 10% planning reserve on the ba

42、isis of planned cost is required. No actual cost should be posted to this WBS element.Corresponding materials assigned to the purchasing activitiesParameters fr Earned-Value AnalysisAll specification activities and Installation II use the 20-80 Method for performance measurement. Procurement activit

46、 the existing enterprise structure.The Project System has no organizational structures of its own; it has to be incorporated into the existing structure by making assignments to the organizational units in Accounting and Logistics. SAP Online Documentation IDES Release 4.0B After that, the project i

47、s broken down into meaningful pieces in a hierarchy reaching from tasks to the lowest level, the work packages.Datastructure in SAP As mentioned above, the project must be incorporated into the existing structure by assigning organizational units in Accounting and Logistics.Source: SAP Online Docume

48、ntation IDES Release 4.0BThis chart provides an overview of what can be assigned to a project and its components. We will define the SAP vocabulary later on.The work-breakdown-structure (WBS) defines the hierarchy of the tasks within a project and divides the project into useful steps.To control cos

49、ts assigned to WBS elements, operative indicators are used.The following operative indicators can be assigned to a WBS element:PlanningWBS elements for which costs can be plannedAccount assignmentWBS elements to which costs can be assignedBillingWBS elements to which revenues can be posted5.2 Implem

50、entation in SAPIn this section we create a new project. We then will have a look at the control parameters. After that we enter the work breakdown structure. Finally, the status concept of SAP R/3 will be explained.Create new project Thus, we get to the initial screen:We enter our project definition

51、, a description of our project and select the standard profile for projects.In our case, we only set a finish date. When pressing Enter, a warning message that this date is not a working day might occur. One can pass the warning by pressing EnterWe then save our work and get the confirmation that th

52、e project has been created.Note: It is wise to save your work from time to time. We will not mention the save procedure in the rest of the manuscript!To continue, we have to choose to change our project.Make sure that the checkbox with activities is always checked. Click execute to proceed.Now he ha

53、ve created a new project. Although we have not keyed in any data except the Project Profile Number, many parameters have already been assigned to our new project. General control parametersClick here to view the global parameters. This section should provide you with a basic insight into which param

54、eters are set. If you feel that the results calculated by R/3 are not logical, you should have an idea where to start searching the relevant customizing details.The project profile specifies general data like Controlling area, Plant, Factory calendar, Planning method etc. When creating the project,

55、the profile is choosen.The network profile specifies general data like settings for the graphical representation, activity parameters, like the currency default of externally processed activities.In the WBS scheduling profile items like the scheduling type (forward, backward) are specified. The budg

56、et profile specifies items like budgeting currency, the valid time horizon for budgeting back in- to the past or into the futureThe planning profile specifies, e.g., costing variant and time horizon.Planning parametersIn the general parameter section, many parameters are set as discussed above. Naturally, one can override a part of them in the current project. However, we are not changing any parameters. Here you can specify if you want to use top-D
