Trigger oldMap

Hi,

I have an after update trigger on opportunity.
I wanted to know what fields are available on an object when I retrieve it from the Trigger.oldMap ?

What I observed is that all fields are not available on the object retrieved from the oldMap and wanted to understand the logic.

Thanks,
Rohit

Rohit, what fields are missing? There is a list of documented fields that have this behavior in the Apex developer guide section called "Invoking Apex > Triggers > Fields that Cannot Be Updated by Triggers".
