Dear All,

I wrote below query and it's working fine. I have one question when to make it datasource.relations(True) OR datasource.relations(false) ?

static void TM_AS_Query(Args _args)
{
Query query;

QueryBuildDatasource datasource;
;
query = new Query();// Add SalesTable main datasource

datasource = query.addDataSource(tableNum(SalesTable));
datasource = datasource.addDataSource(tableNum(SalesLine));
datasource.joinMode(JoinMode::InnerJoin);
datasource.relations(false);

datasource.addLink(fieldNum(SalesTable, SalesId), fieldNum(SalesLine, SalesId));

}

Please give me more shed on this.

Thanks!

Arpan Sen

Thanks Vilmos,

As i understood means if i am going to create a relation between SalesTable and SalesLine with Sales Id filed ( Which is already there in SalesLine table) so, i need to make it

QueryBuildDatasource qbdsSalesTable, qbdsSalesLine;

qbdsSalesTable.relations(false); // False

If i want to do some other relation which is not exist in SalesLine table then i need to put

qbdsSalesTable.relations(True); // True

Please verify.

Thanks!

It is quite obvious. If there is relations defined between the tables or their EDTs are linked to tables, AX would know what the relation is, in which case setting relations(true) would establish the connection between them for you automagically.

If there are no relations defined or you want to change how they are linked, you can override that with relations(false), and define how to link, based on what record context.
