Hi All, I'm hoping someone can help me as have an issue with duplicate data. I have attached a file where you can see my data and have shown the data BEFORE I have added a 'arrange' tool and the data AFTER the arrange tool. This is necessary due to the different versions of my data and something I need to keep. This issue I have is that after the arrange tool it's duplicating the data and I want to keep the line that has data in the last two columns (STATUSVALIDFROM & STATUSCHANGEDTO). Hopefully the attached will make sense of it and show you want I'm trying to achieve! Thank you in advance
