Volitile Parameter Map

[stevenbl]

I am looking at using parameter maps to control the row level access to my data.  I want to base the parameter map on a security table I have in the model.  It contains the userid and access level.  I am having some interesting results and am not sure how these function.  If I make a change to the underlying do I have to republish the package to pick that change up?  I would hope that if the table changes that would automatically be picked up.  Seems that sometimes I can get the change without publishing the package but sometimes not.
Any help would be appreciated.
