Hi Raf,
Thanks for the help but sadly I'd tried that. I have even deleted the transformation and recreated etc. I have even copied the DSO and tried to create a new transformation to the second DSO.
None of which seems to work.
When I create the rule for the first KF the UOM 0UNIT disappears from the list of fields in the DSO shown in the transformation. When I then try to create the second KF rule its as if it no can no longer see 0UNIT.
Thanks
Joel
