Dear Matthew,

  Thanks for the suggestion. Also tried different options. They worked.

Result = [goodsinfo(101, "laptop", "tablet", "iPad"), goodsinfo(102, "notebook",
 "pendrive", "tab")],
 
 findall([X,Y],(member(X,Result),X=goodsinfo{goodsid:101,goodsname:"laptop"},member(Y,Result),Y=goodsinfo{goodsid:102}),Sols).

Thanks and Regards,
Shrirang Edgaonkar

The first argument of findall should be a variable that is given a value
by the success of the second argument.  If, as above, the first argument
does not occur in the second argument, it's almost certainly an error;
you're going to get a list of variables not bound to results.  Try this:

findall(X,(member(X,Result),X=goodsinfo{goodsid:101}),Sols).
