Chapter 27. Designing the case definition You design cases using the process designer in Business Central. Case design is the basis of case management and sets the specific goals and tasks for each case. The case flow can be modified dynamically during run time by adding dynamic tasks or processes. In this procedure, you will create this same case definition to familiarize yourself with the case definition design process. The IT_Orders sample project in Business Central includes the following orderhardware business process case definition. Figure 27.1. orderhardware business process case definition Prerequisites You have created a new case in Business Central. For more information, see Chapter 25, Creating a new IT_Orders case project . You have created the data objects. For more information, see Chapter 26, Data objects . Procedure In Business Central, go to Menu Design Projects and click IT_Orders_New . Click Add Asset Case Definition . In the Create new Case definition window, add the following required information: Case Definition : Input orderhardware . This is usually the subject of the case or project that is being case managed. Package : Select com.myspace.it_orders_new to specify the location that the case file is created in. Click Ok to open the process designer. Define values for the case file variables that are accessible to the sub-processes, subcases, and business rules used in the case. In the upper-right corner, click the Properties icon. Scroll down and expand Case Management , click in the Case File Variables section, and enter the following: Figure 27.2. orderhardware case file variables Note The following case file variables are custom data types: hwSpec : org.jbpm.document.Document (type in this value) survey : Survey [com.myspace.it_orders_new] (select this value) Click Save . Define the roles involved in the case. In the upper-right corner, click the Properties icon. Scroll down and expand Case Management , click in the Case Roles section, and enter the following: Figure 27.3. orderhardware case roles owner : The employee who is making the hardware order request. The role cardinality is set to 1 , which means that only one person or group can be assigned to this role. manager : The employee's manager; the person who will approve or deny the requested hardware. The role cardinality is set to 1 , which means that only one person or group can be assigned to this role. supplier : The available suppliers of IT hardware in the system. The role cardinality is set to 2 , which means that more than one supplier can be assigned to this role. Click Save . 27.1. Creating the Place order sub-process Create the Place order sub-process, which is a separate business process that is carried out by the supplier. This is a reusable process that occurs during the course of case execution as described in Chapter 27, Designing the case definition . Prerequisites You have created a new case in Business Central. For more information, see Chapter 25, Creating a new IT_Orders case project . You have created the data objects. For more information, see Chapter 26, Data objects . Procedure In Business Central, go to Menu Design Projects IT_Orders_New . From the project menu, click Add Asset Business Process . In the Create new Business Process wizard, enter the following values: Business Process : place-order Package : Select com.myspace.it_orders_new Click Ok . The diagram editor opens. Click an empty space in the canvas, and in the upper-right corner, click the Properties icon. Scroll down, expand Process Data , click in the Process Variables section, and enter the following values under Process Variables : Table 27.1. Process variables Name Data Type CaseID String Requestor String _hwSpec org.jbm.doc ordered_ Boolean info_ String caseFile_hwSpec org.jbm.doc caseFile-ordered Boolean caseFile-orderinf String Figure 27.4. Completed process variables Click Save . Drag a start event onto the canvas and create an outgoing connection from the start event to a task and convert the new task to a user task. Click the user task and in the Properties panel, input Place order in the Name field. Expand Implementation/Execution , click Add below the Groups menu, click Select New , and input supplier . click in the Assignments field and add the following data inputs and outputs in the Place order Data I/O dialog box: Table 27.2. Data inputs and assignements Name Data Type Source _hwSpec org.jbpm.document caseFile_hwSpec orderNumber String CaseId Requestor String Requestor Table 27.3. Data outputs and assignements Name Data Type Target ordered_ Boolean caseFile_ordered info_ String CaseFile_orderInfo For the first input assignment, select Custom for the Data Type and input org.jbpm.document.Document . Click OK . Select the Skippable check box and enter the following text in the Description field: Approved order #{CaseId} to be placed Create an outgoing connection from the Place order user task and connect it to an end event. Click Save to confirm your changes. You can open the sub-process in a new editor in Business Central by clicking the Place order task in the main process and then clicking the Open Sub-process task icon. 27.2. Creating the Manager approval business process The manager approval process determines whether or not the order will be placed or rejected. Procedure In Business Central, go to Menu Design Projects IT_Orders_New orderhardware Business Processes . Create and configure the Prepare hardware spec user task: Expand Tasks in the Object Library and drag a user task onto the canvas and convert the new task to a user task. Click the new user task and click the Properties icon in the upper-right corner. Input Prepare hardware spec in the Name field. Expand Implementation/Execution , click Add below the Groups menu, click Select New , and input supplier . Input PrepareHardwareSpec in the Task Name field.

Click the Manager approval user task and create a Data-based Exclusive (XOR) gateway. Create and configure the Place order reusable sub-process: From the Object Library , expand sub-processes , click Reusable , and drag the new element to the canvas on the right side of the Data-based Exclusive (XOR) gateway. Connect the Data-based Exclusive (XOR) gateway to the sub-process. Click the new sub task and click the Properties icon in the upper-right corner. Input Place order in the Name field. Expand Data Assignments and click in the Assignments field and add the following: Click OK . Click the connection from the Data-based Exclusive (XOR) gateway to the sub-process and click the Properties icon. Expand Implementation/Execution , select Condition , and set the following condition expressions. Click the Place order user task and create an end event. Create and configure the order rejected user task: Click the Data-based Exclusive (XOR) gateway and create a new user task. Drag the new task to align it below the Place order task. Click the new user task and click the Properties icon in the upper-right corner. Input Order rejected in the Name field. Expand Implementation/Execution and input OrderRejected in the Task Name field.
