Anaplan List Import Error - "Property-based hierarchy import has disallowed duplicate properties..."

billydix95

Hi there,

 

I have spent a significant amount of time now attempting to get a simple import to work between 2 existing lists for the 299 case study. 

 

I keep receiving the error "Property-based hierarchy import has disallowed duplicate properties for given key in target data - cannot proceed". I have attached below an image of the simple load I am trying to do here, but I have tried to import the same data (product names) from other lists too, with different unique key combinations, and have received the same error.

 

It looks like the import is trying to create new rows, rather than identifying the existing rows that match the unique key (Code > Product Code) and supplementing those records with the additional info.

 

Any help on this would be greatly appreciated!

 

Thanks,

Billy
