How to export data from table to excel through x++ in D365 FO

 Exporting data to excel might be required in most of the scenarios where Data Integration is involved.

Excel can be proved as one of the most significant applications for Data Transformation and manipulations.

Let us see how can achieve the data export using x++ coding standards :-

DocuFileSaveResult           saveResult;

Table1                       table1details , table1datasource , table1update;

PurchAgreementHeader         purchAgreementHeader;

TransDate                    delDate;

FormDataSource               fdsTable1det = sender.formRun().dataSource('Table1');


table1datasource = fdsTable1det.cursor();

select firstonly purchAgreementHeader where purchAgreementHeader.RecId ==                                                                                                            table1datasource.AgreementHeaderRefRecId;

while select forupdate table1update where                                                                                                                         table1update.AgreementHeaderRefRecId ==                                                                                                                table1datasource.AgreementHeaderRefRecId
