Using Local Coordinate System for Velocity Field at Inclined Inlet

Dear all,
I am working on a CFD model to which I want to impose a velocity field at an inclined (wrt the global coordinate system) inlet. For simplicity, let's say I want this velocity field to be (0,0,x) wrt a local coordinate system attached to the inlet. Instead of having to convert (0,0,x) to the global coordinate system (with projections and so on) I would love to be able to define a local coordinate system to reference it to.
I have defined a "Base Vector System 2" relative to the Work Plane I have used to define the inlet (see image). However, when I introduce the velocity field at the inlet as (0,0,sys2.x1), it says "Unkwown variable sys2.x1". What am I missing? Is there an easier way to define this velocity field wrt to the inlet's coordinate system? Any other advice?
Thank you in advance.
Víctor
PS1: wrt = with respect to PS2: I have tried sys2.x1, sys2.x, sys2.xw, wp1.xw, wp1.x1... Nothing seems to be right haha
