For a few weeks both published report and in desktop were refreshing correctly (scheduled in web). Two days ago I started to get failed refresh on the three reports that I had created based on the same data set.
Error being returned in all three reports:
Column '_mcs_commonlocationid_value' in Table 'incidents' contains blank values and this is not allowed for columns on the one side of a many-to-one relationship or for columns that are used as the primary key of a table.
I've checked this column in the Data view and there are no blank records. I checked the relationships in the Model view and this column is not in a relationship with any other table in the model.
Any thoughts would be welcomed.
