Retrieve employee first, last name, middle name X++ / D365FO

There have been many occasion where, we need to split and return employee FirstName, LastName or MiddleName.

This could either be on a form or most times on a report. The below code should help.

DirPersonName dirPersonName;
DirPerson dirPerson;

dirPerson = DirPerson::find(HcmWorker::findByPersonnelNumber(this.PersonnelNumber).Person); // Get the HcmWorker record.
dirPersonName = DirPersonName::find(dirPerson.RecId);

this.FirstName = dirPersonName.FirstName;
this.LastName = dirPersonName.LastName;

Merci
