When attempting to add an Attribute to an Organization in a Constituent Update Batch, the exception 'The INSERT statement conflicted with the CHECK constraint "CK_NAMEFORMAT_VALIDCONSTITUENT". The conflict occurred in database "33433_EC_294"/ table "dbo.NAMEFORMAT". column 'CONSTITUENTID' is received. Adding the same Attribute to an Individual does not have the same issue.
We are currently evaluating this issue and will update this article when we have more information.
