Change negative to positive value

[marsclone]

Hi,

I have a table with invoices (positive values) and bank receivings (negative values).

I want the bank receivings to show positive values, but also calculate the difference what we have billed and what we have received on the bank. 

how do i apply that in a measure?

Thank you in advance!

Hi,

Just Mutiple the value with -1. I mean create a Column as given below.

Column= -1*TableName[ColumnName]

Hi, But that means that the positive values will change to negative?
