Как реализовать GROUP BY?

[TarasNBV]

Table.SETCURRENTKEY(Field1, Field2);

IF Table.FIND('-') THEN REPEAT

...//some code for group processing//...

Table.SETRANGE(Field1, Table.Field1);
Table.SETRANGE(Field2, Table.Field2);
IF Table.FIND('+') THEN;

Table.SETRANGE(Field1);
Table.SETRANGE(Field2);
UNTIL Table.NEXT = 0;
