Question

我在Acumatica项目中添加了许多自定义屏幕，并且我想在这些屏幕上添加批准，因此我找到并遵循了本指南：

How to work with Assignment and Approval Maps in Acumatica via Automation Steps?

这是我的代码：我的DAC：

[PXEMailSource]
[PXPrimaryGraph(typeof(ProductMaint))]
[Serializable]
public class PSSAProduct : IBqlTable, IAssign
{
    #region ProductID
    [PXDBIdentity(IsKey = true)]
    [PXUIField(DisplayName = "Product ID")]
    public virtual int? ProductID { get; set; }
    public abstract class productID : IBqlField { }
    #endregion

    #region ProductCD
    [PXDBString(50, IsUnicode = true)]
    [PXUIField(DisplayName = "Product ID")]
    public virtual string ProductCD { get; set; }
    public abstract class productCD : IBqlField { }
    #endregion

    #region ProductName
    [PXDBString(50, IsUnicode = true, InputMask = "")]
    [PXUIField(DisplayName = "Product Name")]
    public virtual string ProductName { get; set; }
    public abstract class productName : IBqlField { }
    #endregion

    #region Active
    [PXDBBool()]
    [PXDefault(true, PersistingCheck = PXPersistingCheck.Nothing)]
    [PXUIField(DisplayName = "Active")]
    public virtual bool? Active { get; set; }
    public abstract class active : IBqlField { }
    #endregion    

    #region OwnerID
    public abstract class ownerID : IBqlField { }
    [PXDBGuid()]
    [PX.TM.PXOwnerSelector()]
    [PXUIField(DisplayName = "Owner")]
    public virtual Guid? OwnerID { get; set; }
    #endregion

    #region WorkgroupID
    public abstract class workgroupID : IBqlField { }
    [PXDBInt()]
    [PXSelector(typeof(Search<EPCompanyTree.workGroupID>), SubstituteKey = typeof(EPCompanyTree.description))]
    [PX.TM.PXCompanyTreeSelector]
    [PXUIField(DisplayName = "Workgroup", Enabled = false)]
    public virtual int? WorkgroupID { get; set; }
    #endregion

    #region Hold
    [PXDBBool()]
    [PXUIField(DisplayName = "Hold", Visibility = PXUIVisibility.Visible)]
    [PXDefault(true)]
    //[PXNoUpdate] <- Saw this in the PO code, but had to remove so user could save stat of the Hold checkbox
    public virtual bool? Hold { get; set; }
    public abstract class hold : IBqlField { }
    #endregion

    #region Approved
    public abstract class approved : IBqlField { }
    [PXDBBool]
    [PXDefault(false, PersistingCheck = PXPersistingCheck.Nothing)]
    [PXUIField(DisplayName = "Approved", Visibility = PXUIVisibility.Visible, Enabled = false)]
    public virtual bool? Approved { get; set; }
    #endregion


    #region Rejected
    public abstract class rejected : IBqlField { }
    [PXBool]
    [PXDefault(false, PersistingCheck = PXPersistingCheck.Nothing)]
    public bool? Rejected { get; set; }
    #endregion

    #region Status
    [PXDBString(1)]
    [PXDefault(PSSAProduct.Statuses.Hold)]
    [PXUIField(DisplayName = "Status", Visibility = PXUIVisibility.SelectorVisible, Enabled = false)]
    [Statuses.List]
    public virtual string Status { get; set; }
    public abstract class status : IBqlField { }
    #endregion
}

我的图表：

public class ProductMaint : PXGraph<ProductMaint, PSSAProduct>
{
    public PXSelect<PSSAProduct> PSSAProductView;

    public PXSelect<PSSASetupApproval> SetupApproval;

    public EPApprovalAutomation<PSSAProduct, PSSAProduct.approved, PSSAProduct.rejected, PSSAProduct.hold, PSSASetupApproval> Approval;
}

我的设置程序：

    [Serializable]
    public class PSSASetup : IBqlTable
    {
        #region SARequestApproval
        [EPRequireApproval]
        [PXDefault(false, PersistingCheck = PXPersistingCheck.Null)]
        [PXUIField(DisplayName = "SARequest Approval")]
        public virtual bool? SARequestApproval { get; set; }
        public abstract class sARequestApproval : IBqlField { }
        #endregion
    }

还有我的设置批准类：

    [Serializable]
    public class PSSASetupApproval : IBqlTable, IAssignedMap
    {
        #region ApprovalID
        [PXDBIdentity(IsKey = true)]
        [PXUIField(DisplayName = "Approval ID")]
        public virtual int? ApprovalID { get; set; }
        public abstract class approvalID : IBqlField { }
        #endregion

        #region AssignmentMapID
        [PXDefault()]
        [PXDBInt()]
        [PXSelector(typeof(Search<EPAssignmentMap.assignmentMapID, Where<EPAssignmentMap.entityType, Equal<AssignmentMapType.AssignmentMapTypeProduct>>>),
              DescriptionField = typeof(EPAssignmentMap.name))]
        [PXUIField(DisplayName = "Assignment Map ID")]
        public virtual int? AssignmentMapID { get; set; }
        public abstract class assignmentMapID : IBqlField { }
        #endregion

        #region AssignmentNotificationID
        [PXDBInt()]
        [PXSelector(typeof(PX.SM.Notification.notificationID), SubstituteKey = typeof(PX.SM.Notification.name))]
        [PXUIField(DisplayName = "Pending Approval Notification")]
        public virtual int? AssignmentNotificationID { get; set; }
        public abstract class assignmentNotificationID : IBqlField { }
        #endregion

        #region IsActive
        [PXDBBool()]
        [PXDefault(typeof(Search<PSSASetup.sARequestApproval>), PersistingCheck = PXPersistingCheck.Nothing)]
        [PXUIField(DisplayName = "Is Active")]
        public virtual bool? IsActive { get; set; }
        public abstract class isActive : IBqlField { }
        #endregion
    }

    public static class AssignmentMapType
    {
        public class AssignmentMapTypeProduct : Constant<string>
        {
            public AssignmentMapTypeProduct() : base(typeof(PSSAProduct).FullName) { }
        }
    }

我的问题是，如果我将Acumatica的DAC用作EPApprovalAutomation的SourceAssign，它没有错误。但是，如果我使用DAC，它将在框架的代码中引发“ Value不能为空”。

我仔细检查了两个DAC之间的区别，但我什么都没意识到。

我的Acumatica版本是17R2。

如果您知道，请告诉我我想念的是什么。

谢谢！

通常，此错误“值不能为空”与在DB中使用NOT NULL字段定义的表有关，或者与PXDefault属性为DAC且试图持久保存到DB的DAC有关。

如果您在链接中使用了示例，并且使用审计字段创建了数据库表：

CreatedByID uniqueidentifier NOT NULL,
CreatedByScreenID char(8) NOT NULL,
CreatedDateTime datetime NOT NULL,
LastModifiedByID uniqueidentifier NOT NULL,
LastModifiedByScreenID char(8) NOT NULL,
LastModifiedDateTime datetime NOT NULL,
Tstamp timestamp NULL,

确保也将它们添加到DAC：

#region tstamp
public abstract class Tstamp : IBqlField { }
[PXDBTimestamp()]
public virtual byte[] tstamp { get; set; }     
#endregion

#region CreatedByID
public abstract class createdByID : IBqlField { }
[PXDBCreatedByID()]
public virtual Guid? CreatedByID { get; set; }     
#endregion

#region CreatedByScreenID
public abstract class createdByScreenID : IBqlField { }
[PXDBCreatedByScreenID()]
public virtual string CreatedByScreenID { get; set; }          
#endregion

#region CreatedDateTime
public abstract class createdDateTime : IBqlField { }
[PXDBCreatedDateTime()]
public virtual DateTime? CreatedDateTime { get; set; }         
#endregion

#region LastModifiedByID
public abstract class lastModifiedByID : IBqlField { }
[PXDBLastModifiedByID()]
public virtual Guid? LastModifiedByID { get; set; }        
#endregion

#region LastModifiedByScreenID
public abstract class lastModifiedByScreenID : IBqlField { }
[PXDBLastModifiedByScreenID()]
public virtual string LastModifiedByScreenID { get; set; }         
#endregion

#region LastModifiedDateTime
public abstract class lastModifiedDateTime : IBqlField { }
[PXDBLastModifiedDateTime()]
public virtual DateTime? LastModifiedDateTime { get; set; }        
#endregion

还要在代码中签入PXDefault的以下两种可能的候选者：

在PSSAProduct DAC的“状态”字段中，使用[PXDefault(PSSAProduct.Statuses.Hold)]。检查您是否正确定义了PSSAProduct.Statuses。
在PSSASetupApproval DAC的AssignmentMapID字段中，PXSelector [PXSelector(typeof(Search<EPAssignmentMap.assignmentMapID, Where<EPAssignmentMap.entityType, Equal<AssignmentMapType.AssignmentMapTypeProduct>>>), DescriptionField = typeof(EPAssignmentMap.name))]找不到任何记录。您可以进行测试以确保其正常工作。

Answer 2

我设法检查了两个班级之间的区别，然后找到了答案：我错过了NoteID字段

    #region NoteID
    public abstract class noteID : PX.Data.IBqlField
    {
    }
    protected Guid? _NoteID;
    [PXNote(new Type[0], ShowInReferenceSelector = true)]
    public virtual Guid? NoteID
    {
        get
        {
            return this._NoteID;
        }
        set
        {
            this._NoteID = value;
        }
    }
    #endregion
