SAP BODS join (issue with joining 2 varchar fields)

Hi,

  I am trying to join output of two queries and joining on a varchar(255) field. Field Eg: 20150706C-4555510240-LA300007201500

For some reason the fields are not joining though I know there are records with matching fields. I tried ltrim(rtrim()) for both the inputs, did not work.
I tried a cast( varchar255) just to make sure dint work either.

Any suggestion is appreciated, having a hard time to do the join

Am using version 14.2.2.446

Cheers!
