Hi @victor_palacios,

I had a similar problem some time back [Find frist date with non zero value in a time series](https://forum.knime.com/t/find-frist-date-with-non-zero-value-in-a-time-series/29936) and there where a KNIME solution and a python script solution. Maybe you want to check this out. You can easily modify the scripting solution to also remove the tail.

Best Regards,

Paul
