Cell type is consolidated error -- when it is NOT

[donap]

We are running a TI process using the }Cubes dimension as source --- to update the }Cube Security cube cells via TI Process...
We are getting a Cell type is consolidated  error -- and it lists the cubes  (3 of them)
They are DEFINITELY NOT "C" types ( I put a Debug on and output Cubename and Dtype of element.... Output says "S"

What else can I look at ?
Thanks
