 This is the code for exporting data entity using X++

Note: Export is done using batch job, consider it in case of used that on a performance requirement implementation

try

{

EntityName entityName = DMFEntity::findFirstByTableId(tableNum(VendVendorV2Entity)).EntityName;

Query query = new Query(DMFUtil::getDefaultQueryForEntity(entityName));

QueryBuildDataSource qbds = query.dataSourceTable(tableNum(BankPositivePayExportEntity));

DMFEntityExporter exporter = new DMFEntityExporter();

fileId = exporter.exportToFile(entityName,

definitionGroupName,

'', //Optional: ExecutionID

"CSV", //Optional::SourceName

#FieldGroupName_AllFields, //Optional field selection

query.pack(), //Optional: Filtered Query

curExt() //Optional: DataAReaId

);

if (fileId != '')

{

str downloadUrl = DMFDataPopulation::getAzureBlobReadUrl(str2Guid(fileId));

Filename filename = strFmt('export.csv');

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");
