I have a problem with this simple model (look at the picture attached), one of the dimensions has configurations, and has this 3 configs. of this one dimension. But for some reason it is locked, and i am not sure how to unlock it. i tried checking this dimension, but it doesn't say that it is driven. and i don't know how to see is it locked or protected by the design table.
SW 2013 SP5.0
Again as always, thanks to all,
