Data source error: Column '0-30%' in Table 'vw_TargetTool_Hist_2021' contains a duplicate value '<pii>68</pii>' 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. Table: vw_TargetTool_Hist_2021.

Only 7 rows in this view (7 fiscal weeks) so far this year. There are no duplicates. The value '68' only occurs a single time, so it's not even a duplicate value within the column.

Hi duncfair,

Could you check if the relationship cardinality between this table and other tables is set correctly? If these are not set correctly it could also cause a duplicate error, so perhaps that's the culprit.

Hi Tim,

Thanks! I was not the original creator of this report (I'm the backend data guy) and the issue was an auto-created relationship that didn't make any sense. Changing that resolved the error.
