We have a created a sample Any To Any (A2A) transformation "XmlToRelational" with 3 output customer. Please refer the attached sample .car file containing the sample transformation. 



To access the A2A with multiple output parameters in a script, basically just call it like any other procedure that produces multiple outputs. For example:
 

 PROCEDURE p_UseThreeOutputsFromA2A(OUT c3 cursor(i integer, i1 integer))     BEGIN         declare c1 cursor(i integer, v varchar(1024));         declare c2 cursor(i integer, i1 integer);         --declare c3 cursor(i integer, i1 integer); 		call print('c1 cursor');         call /shared/Transformation/"Transform Use Cases"/XmlToRelational(c1, c2, c3);         for r as c1 do             call print(cast(r.i as varchar) || ' ' || r.v);         end for; 		call print('c2 cursor');         for r as c2 do             call print(cast(r.i as varchar) || ' ' || cast(r.i1 as varchar));         end for;     END
