Power BI incremental refresh in Microst Fabric

‎03-04-2024 04:42 AM

 

 

I have implemented Incremental refresh on a Power BI report by using Parameterized Filtering on dates, after publishing the report it get refreshed fine first time but when ever I am trying refresh it again its showing me following duplication error with different tables, even though  there no duplication present in Actual tables. This is the error I get: 

Column '<"Column Name">' in Table '>"Table Name">' contains a duplicate value '<Value>' 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.

can someone help me out.

Hi @DataAnalyst7 

 

This generally happens due to cardinality issues, try to fix that and see what table or column error refers to? This generally guides you to the right direction.

Remember that RangeStart must be inclusive and RangeEnd must be exclusive

 

RangeStart   <=   <"Column Name">   <   RangeEnd
