I have been looking into this a bit further and have managed to find a solution. Don't really understand how it was wrong in the first place.
I exported the Social Network User to XML then had to edit the configuration directly. What I found was on a number of the views there were references to msa_snid even though this field is not anywhere on the views in CRM. After creating a new version on
of the entity in new organization and compared the XML I found that this should have been msa_snuserid.
I replaced every where msa_snid with msa_snuserid in the savedquery second of the xml file and re-imported. This appears to have resolved the problem. I wonder if something had been changed in the entity in the past which did not apply fully. I
just hope there a now further problems resulting from this change I have made.
General on most view I had to make to changes for each view. These were in the fetchxml of the view it was returning msa_snid attribute and I changed it to msa_snuserid and also on the layoutxml change the row from <row name="result" id="msa_snid">
to <row name="result" id="msa_snuserid">
Hope this may be of some help to someone else.
