Forgive me that on Kettle forum but PRD oneis dead - I never got there any answer. Maybe someone will tell you how to solve:

I use PDI where in transformation I have Pentaho Reporting Output step.
In report I use PDI transformation as data source. Path to this transformation is static path, for instance "c:\pdi\workspace\some_job\transformation1.ktr"

Problem is that when I move tranformation to another directory I have to redefine path. How to make it dynamic directory variable? Someting like ${Internal.Entry.Current.Directory} in PDI?
