如何在 ARInvoice 发布后启用 AR301000 header 上的自定义字段？

Question

一些用户字段已添加到 ARInvoice 输入屏幕 (AR301000) 的 top-level 表单中。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？

对于 ARInvoice 条目屏幕，所有 UI 特定于顶级表单的表示逻辑仅在 ARInvoiceEntry BLC 中实现：

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)
        {
            bool isUnreleasedWO = doc.Released != true && doc.DocType == ARDocType.SmallCreditWO;
            bool isUnreleasedPPD = doc.Released != true && doc.PendingPPD == true;

            PXUIFieldAttribute.SetEnabled(cache, doc, false);
            PXUIFieldAttribute.SetEnabled<ARInvoice.dueDate>(cache, doc, (doc.DocType != ARDocType.CreditMemo && doc.DocType != ARDocType.SmallCreditWO && doc.DocType != ARDocType.FinCharge) && doc.OpenDoc == true && doc.PendingPPD != true);
            PXUIFieldAttribute.SetEnabled<ARInvoice.discDate>(cache, doc, (doc.DocType != ARDocType.CreditMemo && doc.DocType != ARDocType.SmallCreditWO && doc.DocType != ARDocType.FinCharge) && doc.OpenDoc == true && doc.PendingPPD != true);
            PXUIFieldAttribute.SetEnabled<ARInvoice.emailed>(cache, doc, true);
            cache.AllowDelete = isUnreleasedWO || isUnreleasedPPD;
            cache.AllowUpdate = true;
            Transactions.Cache.AllowDelete = false;
            Transactions.Cache.AllowUpdate = false;
            Transactions.Cache.AllowInsert = false;

            ..
        }
        else
        {
            ...
        }
        ...
    }
    ...
}

要在 ARInvoice 发布后在 AR301000 顶级表单上启用自定义字段，您应该声明 ARInvoiceEntry 的扩展并按照以下示例订阅 ARInvoice_RowSelected 处理程序：

public class ARInvoiceEntryExt : PXGraphExtension<ARInvoiceEntry>
{
    public void ARInvoice_RowSelected(PXCache sender, 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 
            && !Base.IsProcessingMode && sender.GetStatus(doc) == PXEntryStatus.Inserted;

        if (shouldDisable)
        {
            PXUIFieldAttribute.SetEnabled<ARInvoiceExt.usrCustomTextField>(sender, doc, true);
        }
    }
}
