Dynamics AX Intelligent Data Management Framework

currently assessing whether the IDMF tool for Dynamics AX is worth
implementing at my current workplace.

if you don't know what it is, go here (you'll need your

here is a document i created which may help out, if you happen to be
doing the same thing.

OnlyFetchActive on Form Datasource

this property on the datasource can speed things up especially if you
have one field that has lots of data stored in it and you still want
to show it on the form

if you need to show it on the form (on another tab preferably), you
can use a display method instead.

on the display method

display Memo memoDisplay(TableDS _tableDS)
{
;
if (formTableDS.RecId != _tableDS.RecId)
{
select firstonly log from formTableDS where
formTableDS.RecId == _tableDS.RecId;
}
return formTableDS.memo;
}

formTableDS is declared in the Class declaration of the form
