Failed to resolve name

[Dianica6]

Hi 

Im trying to refresh my power report .All data set comes from Sharepoint. and i get the following message . can you explain what should i do? 

Failed to resolve name 'ift'. It is not a valid table, variable, or function name. Column 'AuditAuditDetail_LookupId' in Table 'Audit Recommendation Action Details' contains a duplicate value '5484' 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.

Thanks

You will need to remove the duplicate values in Power Query from: 

Column 'AuditAuditDetail_LookupId' in Table 'Audit Recommendation Action Details'

For the reference to 'ift' we need more details.  Please add your scripts so we can see where this is referenced.
