I don't have mine configured to ignore errors, but as you have a bunch of these, I would beat that it IS ignoring the errors in the sense that it continues. But there's still a problem and it's letting you know.

You don't provide enough information for me to know for sure, but you are probably either trying to process the cubes and dimensions in the same same or you are not processing the dimension at all. It would be nice if you could use a single step to process both the dimensions and the cubes. These need to be two steps, however, with the dimensions that could have changed processed first, followed with another processing step with that processes the cubes.

This would be nice fix in a future version as I can't think for the life of me why it would ever be better to process the cubes ahead of the dimensions.
