[Aggart9]

Hi

I want to subrtact the values of these two freight vendors. So I want value difference for

2019-07 ~151-87=64, 

2019-08 ~ 141-88= 53

But Cost per Tonne is a measure based on the formula (Total cost/ total tonnes) on below table

Please advise how to do value difference.

Hi,

The next time please share your data in a format that can be pasted in MS Excel.  You may download my PBI file from here.

Hope this helps.

Thank you, It is working!

I tried to post the data from Excel, but I was not not able to, not sure it was only me or there is other way to copy/paste data from Excel.

Hi @Aggart9 

You might consider creating pbix file that will contain some sample data, upload the pbix to onedrive or dropbox and share the link to the file. Please do not forget to describe the expected results based on this sample data.
