Probability & Preventive Maintenance

Dear All,
I want to implement service management in the company I work for and I have pdf file
and also can open service module in the database.
In the service contract quote and service contract, there is a field confusing me
ow to calculate, or it is only assumption or can be left blank and links to
what tables. The field is probability.
I also want to know how to use field Last Preventive Maintenance Date in the service contract line.
I know it means for preventive maintenance date. The Field set to non editable, but how to
generate date in the field. Also, I want to know if Navision can be used for preventive maintenance.
What table, form or report, or fields in Navision relate to preventive maintenance.

Any answers from you are awaited. tku.
