Dynamics 365 工作流

1、新建工作流状态枚举类

2、将枚举类添加到需要实现工作流的表字段里

3、表需要实现canSubmitToWorkflow方法并在需要添加的表单里开启对应的属性

public boolean canSubmitToWorkflow(str _workflowType = '')
    {
        boolean ret;
    
        ret = super(_workflowType);
        
        if(this.WorkFlowStatus == IWS_Luke_WorkFlowStatus::NotSubmitted ||
        this.WorkFlowStatus == IWS_Luke_WorkFlowStatus::Rejected ||
        this.WorkFlowStatus == IWS_Luke_WorkFlowStatus::ChangeRequested )
        {
            ret = true;
        }
        return ret;
    }

//用于更新状态
    public static void updateWorkFlowStatus(RecId _recId,IWS_Luke_WorkFlowStatus _status)
    {
        IWS_OrderHeaderTrain orderHeader;
        if(_recId)
        {
            checkFailed("RecId is incorrect!");
        }
        select firstonly orderHeader where orderHeader.RecId == _recId;
        if(orderHeader)
        {
            ttsbegin;
            orderHeader.selectForUpdate(true);
            orderHeader.WorkFlowStatus = _status;
            orderHeader.update();
            ttscommit;
        }
    }

4、创建一个用于工作流查询的Query

5、创建workflow category

Module 列表里所展示的元素可以在ModuleAxapta基础类里进行扩展，但需要关联到现有的模块里

6、创建workflow type

7、重写workflow type的event handler

public void started(WorkflowEventArgs _workflowEventArgs)
    {
        // TODO:  Write code to execute once the workflow is started.
        Info("TypeEventstarted");
        IWS_OrderHeaderTrain::updateWorkFlowStatus(
            _workflowEventArgs.parmWorkflowContext().parmRecId(),
            IWS_Luke_WorkFlowStatus::PendingApproval);
    }

    public void canceled(WorkflowEventArgs _workflowEventArgs)
    {
        // TODO:  Write code to execute once the workflow is canceled.
        Info("TypeEventcanceled");
        IWS_OrderHeaderTrain::updateWorkFlowStatus(
            _workflowEventArgs.parmWorkflowContext().parmRecId(),
            IWS_Luke_WorkFlowStatus::Rejected);
    }

    public void completed(WorkflowEventArgs _workflowEventArgs)
    {
        // TODO:  Write code to execute once the workflow is completed.
        Info("TypeEventcompleted");
        IWS_OrderHeaderTrain::updateWorkFlowStatus(
            _workflowEventArgs.parmWorkflowContext().parmRecId(),
            IWS_Luke_WorkFlowStatus::Approved);
    }

View Code

8、创建workflow approval

9、重写workflow approval的event handler

public void started(WorkflowElementEventArgs _workflowElementEventArgs)
    {
        // TODO:  Write code to execute once the workflow is started.
        Info("ApprovalEventstarted");
        IWS_OrderHeaderTrain::updateWorkFlowStatus(
            _workflowElementEventArgs.parmWorkflowContext().parmRecId(),
            IWS_Luke_WorkFlowStatus::PendingApproval);
    }

    public void canceled(WorkflowElementEventArgs _workflowElementEventArgs)
    {
        // TODO:  Write code to execute once the workflow is canceled.
        Info("ApprovalEventcanceled");
        IWS_OrderHeaderTrain::updateWorkFlowStatus(
            _workflowElementEventArgs.parmWorkflowContext().parmRecId(),
            IWS_Luke_WorkFlowStatus::Cancelled);
    }

    public void completed(WorkflowElementEventArgs _workflowElementEventArgs)
    {
        // TODO:  Write code to execute once the workflow is completed.
        Info("ApprovalEventcompleted");
        IWS_OrderHeaderTrain::updateWorkFlowStatus(
            _workflowElementEventArgs.parmWorkflowContext().parmRecId(),
            IWS_Luke_WorkFlowStatus::Approved);
    }

    public void denied(WorkflowElementEventArgs _workflowElementEventArgs)
    {
        // TODO:  Write code to execute once the workflow is denied.
        Info("ApprovalEventdenied");
       
    }

    public void changeRequested(WorkflowElementEventArgs _workflowElementEventArgs)
    {
        // TODO:  Write code to execute once change is requested for the workflow.
        Info("ApprovalEventchangeRequested");
        IWS_OrderHeaderTrain::updateWorkFlowStatus(
            _workflowElementEventArgs.parmWorkflowContext().parmRecId(),
            IWS_Luke_WorkFlowStatus::ChangeRequested);
    }

    public void returned(WorkflowElementEventArgs _workflowElementEventArgs)
    {
        // TODO:  Write code to execute once the workflow is returned.
        Info("ApprovalEventreturned");
        IWS_OrderHeaderTrain::updateWorkFlowStatus(
            _workflowElementEventArgs.parmWorkflowContext().parmRecId(),
            IWS_Luke_WorkFlowStatus::Rejected);
    }

    public void created(WorkflowWorkItemsEventArgs _workflowWorkItemsEventArgs)
    {
        // TODO:  Write code to execute once work items are created.
        Info("ApprovalEventcreated");
    }

10、扩展workflow type的submit和workflow approval的resubmit

submit
    
    
     public static void main(Args args)
    {
        //  TODO:  Write code to execute once a work item is submitted.
        WorkFlowComment note="";
        WorkFlowSubmitDialog workflowSubmitDialog;
        WorkFlowCorrelationId workflowCorrelationId;
        WorkFlowTypeName workflowTypeName = workFlowTypeStr('IWS_Luke_WorkFlowType');
        IWS_OrderHeaderTrain orderHeader;

        //open workflow dialog
        workflowSubmitDialog = WorkFlowSubmitDialog::construct(args.caller().getActiveWorkflowConfiguration());
        workflowSubmitDialog.run();

        if(workflowSubmitDialog.parmIsClosedOK())
        {
            //Get comments from the submit to workflow dialog.
            note = workflowSubmitDialog.parmWorkflowComment();
            orderHeader = args.record();
            try
            {
                ttsbegin;


                workflowCorrelationId = workflow::activateFromWorkflowType(workflowTypeName,orderHeader.RecId,note,NoYes::No);

                orderHeader.selectForUpdate(true);
                orderHeader.WorkFlowStatus = IWS_Luke_WorkFlowStatus::Submitted;
                orderHeader.update();

                ttscommit;
                info("审批通过!");
            }
            catch(Exception::Error)
            {
                error("审批不通过!");
            }
        }

        args.caller().updateWorkFlowControls();
        if(orderHeader)
        {
            if(orderHeader.dataSource())
            {
                orderHeader.dataSource().research(true);
                orderHeader.dataSource().active();
            }
        }

    }
