Get customer or prospects in Dynamics AX 2012

问题

I am trying to get customer or prospect using X++ and use it on a lookup. There is a method in the DirPartyTable that returns what I want.

DirPartyTable::isCustomerOrRelation

while select * from dirPartyTable
{
       if(DirPartyTable::isCustomerOrRelation(dirPartyTable.RecId))
       {

                //Get the Name
                //info(dirPartyTable.Name);
       }
}

But when I build a query to the lookup I am trying to pass the DirPartyTable::isCustomerOrRelation(dirPartyTable.RecId) on the addRange of the query somehow. Is there a way to do it or is it impossible ?

回答1:

If you go to the source of isCustomerOrRelation (and isCustomer and isRelation) you see, that the method returns true if a customer or prospect exists in the current company.

Your while select, while correct, is inefficient, because it may have to scan a million parties to select on thousand customers or prospects present in you current company.

A more efficient, but syntactical illegal, while select would be:

while select * from dirPartyTable
   exists join custTable
   where custTable.Party == dirPartyTable.RecId
   union 
   select * from dirPartyTable
   exists join smmBusRelTable
   where smmBusRelTable.Party == dirPartyTable.RecId;
{
     info(dirPartyTable.Name);
}

While illegal in X++ it is possible using queries and views.

Make two queries (translate to appropriate properties yourself):

Query1:

select * from dirPartyTable
    exists join custTable
    where custTable.Party == dirPartyTable.RecId

Query2:

select * from dirPartyTable
    exists join smmBusRelTable
    where smmBusRelTable.Party == dirPartyTable.RecId;

Make two views (View1 and View2) based on the queries.
Make a union query (Query3), see how to Combine Data Sources in a Union Query, remember to specify the UnionType (Union or UnianAll).
Make a view based on the Query3, see how to Create a View Based on a Query.

Result, select all records using X++:

while select * from dirPartyCustOrRelationTable
{
     info(dirPartyCustOrRelationTable.Name);
}

Or you can use the Query3 directly to retrieve the records.
