Hi REPORTES_WILSON ,

 

The results of the unified column can be achieved by creating metric values, refer to the following test results:

M1 = 
SWITCH (
    MAX ( Category[Categoy] ),
    "a", SUM ( Table1[subtotal] ),
    "b", SUM ( Table2[subtotal] ),
    "c", SUM ( Table3[subtotal] ),
    "d", SUM ( Table4[subtotal] )
)

M2 = 
SWITCH (
    MAX ( Category[Categoy] ),
    "a", SUM ( Table1[IVA] ),
    "b", SUM ( Table2[IVA] ),
    "c", SUM ( Table3[IVA] ),
    "d", SUM ( Table4[IVA] )
)

 

If the problem is still not resolved, please provide detailed error information and test data. Looking forward to your reply.

Best Regards,
Henry
