Query filtering compare two values

Hi all,

I have a form on AX 2012 R3 CU9 where I'd like to filter comparing two fields on the line. For example, where integer in value SalesLine.FieldA is more than integer in value SalesLine.FieldB

(I should state in advance that these fields are from a view, I don't know if that changes anything)

Is this possible? The only thing I can find is comparing date values

Thanks very much in advance

Luke
