It's a faster way of fetching if you know that you only have 1
corresponding record per parent record, such as the InventTableModule
data sources on the InventTable form. They are (each individual DS),
1:1, although that property is not exposed in the GUI -- the forms
developers chose to link child data sources differently than reports &
queries for some reason -- hopefully they'll fix it some day... So for
now, it's settable on reports and queries only, unless you build your
own through code.

Subject: [development-axapta] Fetchmode vs JoinMode
I'm a bit confuse about fetchmode and joinmode, what is exactly the
two method means ?
'cause sometimes a report can use fetch mode, but with value of
joinmode
for example :
QueryBuildDataSource1 = Query.adddatasource(tablenum(SalesTable));
QueryBuildDataSource2 = QueryBuildDataSource1.adddatasource(tablenum
(LedgerJournalTrans));
QueryBuildDataSource2.addlink(fieldnum(SalesTable, SalesId), fieldnum
(LedgerJournalTrans, SalesId));
QueryBuildDataSource2.JoinMode(JoinMode::Existjoin)
.
.
.
and then I see in some example using FetchMode, like this :
QueryBuildDataSource2.FetchMode(JoinMode::ExistJoin);
.
.
NB: the two example actually not related, but the point is, Is it
right to join table with FetchMode like example no.2 ? Example no 1
seems more logic to me....
I appreciate any kind of information :))
Thanks,
