I can't believe I'm asking such a rookie type question but it has me really perplexed!

I am trying to create a period movement consolidation in a dimension, which will be the sum of one period less another. eg 201502 MVMT = 201502 less 201501.
The children already exist, so I am simply editing the dimension, inserting the consolidated element and then copying and pasting the children into it. I then try to edit the weighting on 201501 by right clicking and selecting Element Properties only to find that the weighting is greyed out. ( The element type is editable but not the weighting )
If I added a new element to the consolidation by selecting insert child, then I can edit the weighting but not if I copy and paste and of course I can't use insert child if the child already exists
A colleague of mine tried exactly the same thing, but he is able to edit the element properties. The only difference between us is that he is running on a desktop installation whereas I am using a citrix client (both running 9.5.2) . I can only assume that it is some kind of ini settings but I've looked through his ini file and can't see anything. My ini file is not available to me to view

I do know that I can do this using TI and will probably do that (or use his machine) but I wondered if anyone knew why the weighting was greyed out
Help much appreciated!
