Hi @Anonymous 

Please create relationships among these tables,

https://docs.microsoft.com/en-us/power-bi/desktop-create-and-manage-relationships

Then you can sum for mutiple columns using DAX

Or use lookup function.

Some similar threads you could refer to;

Hi @Anonymous ,

Try:

M1 =  Sum (Table1[ColumnA])

M2 =  Sum (Table2[ColumnX])

M3 =  Sum (Table3[ColumnZ])

MFinal = M1+M2+M3

If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos are nice too.
