How do I organize data and rank it?

[jvelasqu3]

Hello everyone
User
I have the table that contains the following fields:
LLAVECP,
CENTRO,
PLU_SAP,
NumeroSemana,
Venta_UND
I need the data to be ranked according to the Venta_UND field value for each LLAVECP

[hic]

Make a chart with LLAVECP as dimension, and Rank(Sum(Venta_UND)) as measure.
