Two plugins in one day! wow!
This one was, in fact, developed a couple of months ago.
One of my colleague was using a solution from my fellow MVP Andrii Butenko which allows to import/export NN relationships in a silverlight web resource. This was nice but my colleague was using other attributes than primary key to do the mapping and Andrii’s solution does not support this.
So he asked me to develop a XrmToolBox’s plugin that could do this.
And, here it is! You can select entities and relationships and moreover, choose mapping attributes on both enitities. I only let text and number attributes selectable as other does not really make sense for mapping purposes.
Then you can import or export NN relationships!
Here is a preview
As usual, this plugin, among other, is available with XrmToolBox on CodePlex
