在 Acumatica 中使用自定义屏幕的批准

Question

我在我的 Acumatica 项目中添加了许多自定义屏幕，我想对这些添加批准，所以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;
}

我的设置类：

    [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 apprval 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 作为 EPApprovalAutomation 的 SourceAssign，它没有错误。但是如果我使用我的 DAC，它会在框架的代码中抛出“Value cannot be null”。

我仔细检查了两个 DAC 之间的区别，但我没有意识到任何事情。

我的 Acumatica 版本是 17R2。

如果你知道，请告诉我我错过了什么。

谢谢大家！

Answer 1

通常，此错误“Value cannot be null”与在 DB 中定义的具有 NOT NULL 字段的表有关，或者与尝试持久保存到 DB 时 PXDefault 属性为空的 DAC 有关。

如果您使用了链接中的示例，并且您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,

确保您也将它们添加到您的 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

同时检查您的代码这两个可能的 PXDefault 候选：

1. 在PSSAProduct DAC 的状态字段中，您使用[PXDefault(PSSAProduct.Statuses.Hold)]。检查您是否正确定义了 PSSAProduct.Statuses。

2. 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。您可以使用视图进行测试以确保其正常工作。

我设法检查了两个班级之间的差异，然后我找到了答案：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
