Help to know the error with Calculate

[Anonymous]

I am following this example.

http://www.daxpatterns.com/abc-classification/

When I compare the result I have difference and I don't know why?

When I go to check it the source and I find this, I have a Column FDCODIGO with the same line two times, My problem is I don't understand why duplicate the result in the measure TotalProductos

I hope somebody can help me to understand the error.

Sorry my English is bad.

Do have relationship with any other table?

How about data in the source system?

It is a only table, I want cumulative the column "ventas netas", When I used a Measure I don't have problem, it is when I create a column.

Same syntax with a Measure or a Column have different result

Is the Context where the  Dax Formula is evaluated.

In a Column if you have duplicates this consider all in the sum process.

One question for newbies, what is the difference between Measure and column, I am sorry but I don't have the clear concept

[Vvelarde · Accepted solution]

A calculated column is added to the data model

A measure is calculated when is add to a visual or when you use in a dax Formula.

A better explanation of his difference you can visit this:
