Hello,
I am new here and new to BI.
I have a table with postcodes and locations, e.g.
AL10 0AB Hatfield
AL10 0AB Hatfield
DN4 0QN Doncaster
DN4 0QN Sheffield
DN4 0QN Leeds
where postcode is in one column and a location is in another.
I want to create a new column which will tell me where I have duplicate (repeating) postcodes that are allocatied to a different location. In above list, AL10 0AB would return a NO or FALSE becuase it's a duplicate at the same location. However, DN4 0QN would return YES or TRUE.
Many thanks for your help in advance.
Nena
