Hi @danilo_inovacao, you can use the attribute manager to copy the date into a new attribute, format it using de s setting and sorting + sampling twice once for the min and secondly for the max.

Hope this helps

To add to Itay's answer, use a DateFormatter to format the dates as YYYYMMDD and either use the Sorter/Sampler pattern or use the StatisticsCalculator to get the min/max values.

Thanks @itay and @david_r by suggestions of transformers.

I have a register that is not works perfect:

Attached my template.

Thanks in Advance,

Hi @danilo_inovacao I think it has to do with the fact that you are grouping via the statisticscalculator, and possibly missing out on the " symbol in the date formatter had something to do with it too, but not sure...have a look at my take of it (with a little help from @takashi 's transformer)3

Hope this helps
