Export data entity through code Dynamics 365 Finance and Operations X++

Fellows, In this blog I will let you know about how to execute data entity export job through code.

 #DMF
 SharedServiceUnitFileID fileId;
 DMFDefinitionGroupName definitionGroupName = "MyUniqueDefinitionGroupName";

 try
 {   
     EntityName           entityName = DMFEntity::findFirstByTableId(tableNum(BankPositivePayExportEntity)).EntityName;

     // Start:Optional if you want to filter data while exporting
     Query                query = new Query(DMFUtil::getDefaultQueryForEntity(entityName));
     QueryBuildDataSource qbds = query.dataSourceTable(tableNum(BankPositivePayExportEntity));
     SysQuery::findOrCreateRange(qbds, fieldNum(BankPositivePayExportEntity, PositivePayNumber)).value(bankPositivePayTable.PositivePayNum);   
     // End

     DMFEntityExporter exporter = new DMFEntityExporter();
     fileId = exporter.exportToFile(entityName,
                                    definitionGroupName,
                                    '1234567890', //Optional: ExecutionID
                                    "XML-Attribute", //Optional::SourceName
                                    #FieldGroupName_AllFields, //Optional field selection
                                    query.pack(), //Optional: Filtered Query
                                    curExt() //Optional: DataAReaId
                                    );

     if (fileId != '')
     {         
         str downloadUrl = DMFDataPopulation::getAzureBlobReadUrl(str2Guid(fileId)); 

         System.Uri uri = new System.Uri(_sourcefile);
         str fileExt;

         if (uri != null)
         {
             fileExt = System.IO.Path::GetExtension(uri.LocalPath);
         }

         Filename filename = strFmt('MyFirstExport%1',fileExt);
         System.IO.Stream stream = File::UseFileFromURL(downloadUrl);
         File::SendFileToUser(stream, filename);         
     }
     else
     {
         throw error("DMF execution failed and details were written to the execution log"); 
     }
 }
 catch
 {
     error("error occurred while exporting");
 }

That's it,
Hope it helps.
