Question

某些用户字段已添加到ARInvoice输入屏幕（AR301000）。用户字段存在于“事务”网格中。它们只是文本字段。没有关联的自定义逻辑，并且绑定到DB表。

用户希望在发票发布后修改特定的用户文本字段 - 实现此目的的最佳方法是什么？

Answer 1

值得庆幸的是，ARInvoces输入屏幕上的交易网格永远不会被自动化步骤禁用。事务网格的所有UI表示逻辑仅在ARInvoiceEntry BLC中定义：

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ARInvoice发布后在AR301000上启用自定义字段，您应完成以下相关简单步骤：

为ARInvoice_RowSelected事件处理程序中的ARTran缓存设置 AllowUpdate 为 true
调用静态 PXUIFieldAttribute.SetEnabled 方法以禁用所有ARTran字段，但用户想要修改的特定自定义文本字段除外

下面列出了完整的代码段：

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);
        }
    }
}
