如何通过Print management 打印SSRS报表（how-to-print-ssrs-report-using-print-management）

报表打印管理Print management

添加一个新的Report format

如下图为Customer invoice添加两个新的Report format

图中的两个Report format可以通过添加一下代码可以实现

[ExtensionOf(classStr(PrintMgmtReportFormatPopulator))]
public final class PrintMgmtReportFormatPopulator_Demo_Extension
{
    #PrintMgmtSetup
 
    protected void addDocuments()
    {
        // Add new customized reports
        this.addOther(PrintMgmtDocumentType::SalesOrderInvoice, ssrsReportStr(DocSalesInvoice, Report), ssrsReportStr(DocSalesInvoice, Report), #NoCountryRegionId);
        this.addOther(PrintMgmtDocumentType::SalesOrderInvoice, ssrsReportStr(DocSalesInvoiceExt, Report), ssrsReportStr(DocSalesInvoiceExt, Report), #NoCountryRegionId);
        // Add the standard report design, because of PrintMgmtDocType.getDefaultReportFormatDelegate()
        this.addOther(PrintMgmtDocumentType::SalesOrderInvoice, ssrsReportStr(SalesInvoice, Report), ssrsReportStr(Sal
        next addDocuments();
    }
}

下次打开Print management setup的时候，PrintMgmtReportFormat 表中就会添加了 2 条新记录。

改变默认的 Report format

如果您需要更改Original/Copy preview的默认的 Report format，Microsoft 建议修改PrintMgmtDocType.getDefaultReportFormatDelegate()：

class THK_PrintMgmtDocTypeEventHandler
{
  [SubscribesTo(classStr(PrintMgmtDocType), delegateStr(PrintMgmtDocType, getDefaultReportFormatDelegate))]
  public static void PrintMgmtDocType_getDefaultReportFormatDelegate(PrintMgmtDocumentType _docType, EventHandlerResult _result)
  {
      switch (_docType)
      {
          case PrintMgmtDocumentType::SalesOrderInvoice:
              _result.result(ssrsReportStr(DocSalesInvoice, Report));
              break;
      }
  }
}

打印Original/Copy preview的时候，系统目前仍然会打印默认的Report format，而非用户下拉选择的Format（Bug？），因此需要通过一下代码修复：

class THK_PrintMgmtDocTypeEventHandler
{
  [SubscribesTo(classStr(PrintMgmtDocType), delegateStr(PrintMgmtDocType, getDefaultReportFormatDelegate))]
  public static void PrintMgmtDocType_getDefaultReportFormatDelegate(PrintMgmtDocumentType _docType, EventHandlerResult _result)
  {
      switch (_docType)
      {
          case PrintMgmtDocumentType::SalesOrderInvoice:
              _result.result(ssrsReportStr(DocSalesInvoice, Report));
                  PrintMgmtReportFormatName formatName = THK_PrintMgmtDocTypeEventHandler::getPrintMgmtReportFormat(_docType);
                  if (formatName)
                  {
                      _result.result(formatName);
                  }
                  else
                  {
                      _result.result(ssrsReportStr(SalesInvoice, Report));
                  } 
              break;
      }
  }
  public static PrintMgmtReportFormatName getPrintMgmtReportFormat(PrintMgmtDocumentType    _printMgmtDocumentType)
  {
      PrintMgmtDocInstance printMgmtDocInstance;
      PrintMgmtReportFormat printMgmtReportFormat;
      PrintMgmtSettings printMgmtSettings;
 
      select firstonly DocumentType, RecId from printMgmtDocInstance
      where printMgmtDocInstance.DocumentType == _printMgmtDocumentType
      join ParentId, ReportFormat from printMgmtSettings
          where printMgmtSettings.ParentId == printMgmtDocInstance.RecId
      join RecId, DocumentType, Name from printMgmtReportFormat
          where printMgmtReportFormat.RecId == printMgmtSettings.ReportFormat
          && printMgmtReportFormat.DocumentType == _printMgmtDocumentType;
 
      return printMgmtReportFormat.Name;
  }
}

添加一个新的Document type

通过以下步骤可以添加一个新的Document type

创建PrintMgmtDocumentType的Coc扩展，添加一个新的节点

创建Node class ( 例如PrintMgmtNode_Purch)中方法getDocumentTypes的Coc扩展 

[ExtensionOf(classStr(PrintMgmtNode_Purch))]
public final class PrintMgmtNode_Purch_Demo_Extension
{
    /// 
 
    /// Gets a list of valid document types for the node.
    /// 
 
    /// 
    ///    A list of valid document types for the node.
    /// 
    /// 
    /// The results can vary based on what is configured in the application because configuration keys are
    ///    used to determine this list.
    /// 
    public List getDocumentTypes()
    {
        List ret = next getDocumentTypes();
 
        ret.addEnd(PrintMgmtDocumentType::customPurchPromptLetter);
 
        return ret;
    }
 
}

之后就可以在Print management 中看到我们新加的节点了

创建新的Form letter类

这个类用来返回 hierarchy 和前面创建的document type

[PrintMgmtDocumentTypeFactoryAttribute(PrintMgmtDocumentType::customPurchPromptLetter)]
public class customPurchFormLetterReport_PromptLetter extends PurchFormLetterReport
{
    /// 
 
    /// Returns the default printer settings for the specified PrintSetupOriginalCopy enumeration value.
    /// 
 
    /// 
    /// The PrintSetupOriginalCopy enumeration value that specifies whether the Original
    /// or Copy destinations should be retrieved.
    /// 
    /// 
    /// The default printer settings for the specified PrintSetupOriginalCopy enumeration value.
    /// 
    /// 
    /// The general pattern for implementing this method is to use the printer destinations from the appropriate
    /// FormLetter class.  These printer destinations will be used if no Print Management destinations are
    /// found or used.
    /// 
    protected container getDefaultPrintJobSettings(PrintSetupOriginalCopy _printCopyOriginal)
    {
        if (_printCopyOriginal == PrintSetupOriginalCopy::Original)
        {
            return PurchFormLetter::getPrinterSettingsFormletter(DocumentStatus::None,PrintSetupOriginalCopy::Original);
        }
        else
        {
            return PurchFormLetter::getPrinterSettingsFormletter(DocumentStatus::None,PrintSetupOriginalCopy::Copy);
        }
    }
 
    /// 
 
    /// Returns the PrintMgmtDocumentType enumeration value that specifies what document this FormLetterReport class controls.
    /// 
 
    /// 
    /// The PrintMgmtDocumentType enumeration value that specifies what document this FormLetterReport class controls.
    /// 
    /// 
    /// This value is used to retrieve the appropriate Print Management settings for the report.
    /// 
    public PrintMgmtDocumentType getPrintMgmtDocumentType()
    {
        return PrintMgmtDocumentType::customPurchPromptLetter;
    }
 
    /// 
 
    /// Returns the PrintMgmtHierarchyType enumeration value that specifies what hierarchy this FormLetterReport class uses.
    /// 
 
    /// 
    /// The PrintMgmtHierarchyType enumeration value that specifies what hierarchy this FormLetterReport class uses.
    /// 
    /// 
    /// This value is used to retrieve the appropriate Print Management settings for the report.
    /// 
    protected PrintMgmtHierarchyType getPrintMgmtHierarchyType()
    {
        return PrintMgmtHierarchyType::Purch;
    }
 
    /// 
 
    /// Returns the PrintMgmtNodeType enumeration value that specifies what node this FormLetterReport class uses.
    /// 
 
    /// 
    /// The PrintMgmtNodeType enumeration value that specifies what node this FormLetterReport class uses.
    /// 
    /// 
    /// This value is used to retrieve the appropriate Print Management settings for the report.
    /// 
    protected PrintMgmtNodeType getPrintMgmtNodeType()
    {
        return PrintMgmtNodeType::PurchTable;
    }
}

最后Coc扩展populator类

这个类的作用可以参考前文“添加一个新的Report format”

/// 
 
/// Populates the PrintMgmtReportFormat table used for print management with the MyProject documents.
/// 
 
[ExtensionOf(classStr(PrintMgmtReportFormatPopulator))]
public final class PrintMgmtReportFormatPopulatorAppSuite_custom_Extension
{
    #ISOCountryRegionCodes
    #PrintMgmtSetup
 
    protected void addDocuments()
    {
        // Purchasing documents
        this.customAddPurchaseDocuments();
 
        next addDocuments();
    }
 
    /// 
 
    /// Adds purchase records to the PrintMgmtReportFormat table.
    /// 
 
    protected void customAddPurchaseDocuments()
    {
        this.addOther(PrintMgmtDocumentType::customPurchPromptLetter, ssrsReportStr(customPurchPromptLetterReport, Report), ssrsReportStr(customPurchPromptLetterReport, Report), #NoCountryRegionId);
    }
 
}

完成！
