Hi All,
i need to add a free table to form DE at run time (load event ) event and remove it at destroy event

yes you may ask you can load it at load event instead of add to DE but this is a special issue and
working from DE so ;

i have tried to add a free table to DE at run time like below but unsuccessful :(

how would be your suggestions ?
TIA

this.Dataenvironment.addObject('MyCursor','Cursor')
this.Dataenvironment.MyCursor.cursorsource='mytable'
this.Dataenvironment.MyCursor.alias='mytable'
