ARInvoice發佈後如何在AR301000上啓用自定義字段？

Question

某些用戶字段已添加到ARInvoice輸入屏幕（AR301000）。用戶字段存在於交易網格中。它們只是文本字段。沒有關聯的自定義邏輯，並綁定到數據庫表。

用戶希望在發票發佈後修改特定的用戶文本字段 - 實現此目的的最佳方法是什麼？

謝天謝地，ARInvoces輸入屏幕上的事務網格從未被自動化步驟禁用。所有的交易格UI演示邏輯是隻有ARInvoiceEntry BLC中定義：

public class ARInvoiceEntry : ARDataEntryGraph<ARInvoiceEntry, ARInvoice>, PXImportAttribute.IPXPrepareItems 
{ 
    ... 
    protected virtual void ARInvoice_RowSelected(PXCache cache, PXRowSelectedEventArgs e) 
    { 
     ARInvoice doc = e.Row as ARInvoice; 
     if (doc == null) return; 

     ... 
     bool shouldDisable = doc.Released == true 
          || doc.Voided == true 
          || doc.DocType == ARDocType.SmallCreditWO 
          || doc.PendingPPD == true 
          || doc.DocType == ARDocType.FinCharge && !IsProcessingMode && cache.GetStatus(doc) == PXEntryStatus.Inserted; 
     if (shouldDisable) 
     { 
      ... 
      Transactions.Cache.AllowDelete = false; 
      Transactions.Cache.AllowUpdate = false; 
      Transactions.Cache.AllowInsert = false; 
      ... 
     } 
     else 
     { 
      ... 
      Transactions.Cache.AllowDelete = true; 
      Transactions.Cache.AllowUpdate = true; 
      Transactions.Cache.AllowInsert = 
       doc.CustomerID != null && 
       doc.CustomerLocationID != null && 
       doc.DocType != ARDocType.FinCharge && 
       (doc.ProjectID != null || !PM.ProjectAttribute.IsPMVisible(this, BatchModule.AR)); 
      ... 
     } 
     ... 
    } 

    protected virtual void ARTran_RowSelected(PXCache sender, PXRowSelectedEventArgs e) 
    { 
     ARTran row = e.Row as ARTran; 
     if (row != null) 
     { 
      PXUIFieldAttribute.SetEnabled<ARTran.defScheduleID>(sender, row, row.TranType == ARInvoiceType.CreditMemo || row.TranType == ARInvoiceType.DebitMemo); 
      PXUIFieldAttribute.SetEnabled<ARTran.deferredCode>(sender, row, row.DefScheduleID == null); 
     } 
    } 
    ... 
} 

要在AR301000啓用自定義字段中的ARInvoice發佈後，您應完成以下relatevely簡單的步驟：

1. 設置AllowUpdate到真正爲ARInvoice_RowSelected事件處理程序中的ARTran緩存

2. 調用靜態PXUIFieldAttribute.SetEnabled方法來禁用所有ARTran領域，除了特定的自定義文本字段，用戶要修改

完整的代碼片段如下：

public class ARInvoiceEntryExt : PXGraphExtension<ARInvoiceEntry> 
{ 
    private bool IsDisabled(ARInvoice doc) 
    { 
     return doc.Released == true 
      || doc.Voided == true 
      || doc.DocType == ARDocType.SmallCreditWO 
      || doc.PendingPPD == true 
      || doc.DocType == ARDocType.FinCharge 
      && !Base.IsProcessingMode 
      && Base.Document.Cache.GetStatus(doc) == PXEntryStatus.Inserted; 
    } 

    public void ARInvoice_RowSelected(PXCache cache, PXRowSelectedEventArgs e) 
    { 
     ARInvoice doc = e.Row as ARInvoice; 
     if (doc == null) return; 

     if (IsDisabled(doc)) 
     { 
      Base.Transactions.Cache.AllowUpdate = true; 
     } 
    } 

    public void ARTran_RowSelected(PXCache sender, PXRowSelectedEventArgs e) 
    { 
     var doc = Base.Document.Current; 
     ARTran row = e.Row as ARTran; 

     if (row != null && doc != null && IsDisabled(doc)) 
     { 
      PXUIFieldAttribute.SetEnabled(sender, row, false); 
      PXUIFieldAttribute.SetEnabled<ARTranExt.usrCustomTextField>(sender, row, true); 
     } 
    } 
}
