Opciones de Programación

Buenas. No puedo establecer fechas ni duraciones. Tengo bloqueado ese icono. Agradecería ayuda. Gracias.

We don’t speak Spanish, sorry. Your message translated with Google Translate looks as follows:

Hello good. I cannot set dates or durations. I have that icon blocked. I would appreciate help. Thank you.

Please consider using English for better understanding.

You may want to read the FAQ to learn about the cases when dates can’t be changed. In your case it is likely to be a summary task.
