Issue: I tried to setup a workflow configuration based on the Project field on the purchase requisition. For some reason the Project field was looking up the dimensions. I had a look at what dimensions I had in the system and I found the 4th dimension was called Project too. Because the workflow class builds a list on the field names. It only adds 1 field called Project. In other words, only allowing you to select 1 of the two fields labelled Project. Solution: I renamed the dimension to "Project No". Something different.
