Settings for Plan
To make the plan work properly, we need to set the following settings:
1. Settings on Fields
In Agricultural - Field we have to set date Valid from and Valid To.

2. Creating EM - Expert model:
If we want to plan crop on crop area we, have to create also Expert model (EM), because the EM is the key to plan our work. How to create new EM or new version of EM we can read user manual for Expert model.
By creating EM it is also important, that we have on Item set data about secondary classification also.

If we need new secondary classification,we can create them in module Items Categories.
