Just a hint here, when you use the AGGR function in a table/chart you will get unpredictable results if you do not aggregate over the existing dimensions as well as the additional ones you want. This is because the AGGR function ignores any dimensions currently in the table.
In your example it means that the AGGR function should aggregate over Ano, Vendedor & MES as well as Emis_Month so your expression should look like:
=AGGR ( SUM (SALES.tot_neto ) , ANO , VENDEDOR , MES , SALES.Emis_Month ) Of course, I'm guessing at your dimension names and just using the labels you have in your pivot, so you should replace those above with the actual field names in use. Hope it helps,</body>
