Lock opportunity

[rslemer]

Is possible lock any new changes when opportunity sales stage is closed win, or close lost ?

I need restrict new modification only a admin user.

Yes, you should be able to do this easily. There are at least four ways:

1.- Freeze procedure
Which more or less goes like this:

• make the module private, so all users can see only their records
• create one user in his own hierarchy/role
• add an exception so that all users can share their opportunities except this one user
• add an exception so that special user shares his opportunities in read only mode
• add a workflow that assigns all closed opportunities to this special user
  

2.- Record Access Control Business Rule

3.- Special Permission Hooks

4.- Direct Code manipulation
