Deleting Profit Centres and removing them from Profit Centre Groups

Hi,

I have recently deleted some 3000+ unused profit centres from our system. However the problem I'm having is that these existed in a number of profit centre groups and the values are still

displaying with the text "no valid master record".

Is there a quick way to remove these from the profit centre groups as I don't relish the prospect of removing them all manually. The standard hierarchy is not a problem they have autoatically been removed from there.

thanks in advance.

Paul.
