Calculate total cost of projects but removing duplicates

[DylanBanINT]

Hi, I am trying to calculate the total cost of all my projects, however my projects are in multiple parts but the cost at the end of each part is still the same

Project Name	Project Part	Budget
Project 1	Part 1	£123.45
Project 1	Part 2	£123.45
Project 1	Part 3	£123.45
Project 2	Part 1	£45.95
Project 2	Part 2	£45.95
Project 3	Part 1	£68.72
Project 3	Part 2	£68.72
Project 3	Part 3	£68.72
Project 3	Part 4	£68.72
Project 3	Part 5	£68.72

Example table above, I want to calculate the total amount of the budget column however I only want to do it for each project and remove any duplicates so that the total amount I should get should be ££238.12

Unfortunately I cannot do this manually as the data gets update live on Sharepoint so I will need a formula for this! Thanks in advance for anyone that can help.

@DylanBanINT ,

Create a measure like

Sumx(summarize(Table, Table[Project Name], Table[Budget]), [Budget])

Hi, what does the 'Table' parts do in this?
