D365 FO - How to trigger electronic reporting using X++ to export the file

 Scenario: On clicking the button, electronic reporting should be triggered to export the data based on the input parameter (Journal number) and attach the file against the journal header

ERFormatMappingId      formatMappingId;        

ERFormatMappingTable      mappingTable; 

ERIFormatMappingRun formatMappingRun;

const str erParmJournalNum = 'parameters.JournalNum’;

FileName   downloadfileName = paymentProcessingSetup.fileName + today();

// Add the input parameter – journal num so that it export the lines only for that journal

ERModelDefinitionInputParametersAction modelDefinitionInputParametersAction = new ERModelDefinitionInputParametersAction();

modelDefinitionInputParametersAction. addParameter(erParmJournalNum, _journalNum)

// export the data in the file based on the input parameters by setting electronic reporting ID and file name 

formatMappingRun = ERObjectsFactory::createFormatMappingRunByFormatMappingId(paymentProcessingJournalSetup.ERID,  paymentProcessingSetup.fileName).withParameter(modelDefinitionInputParametersAction);

 // attach the file to attachments in journal header

Var  fileDestination = ERObjectsFactory::createFileDestinationAttachmentWithDocuType(directDebitHeader, ‘File’);

formatMappingRun.withFileDestination(fileDestination);

formatMappingRun.parmShowPromptDialog(false);

formatMappingRun.run();
