Scenario refers to the type of the data in your application. Actual, Budget, Plan, Forecast
In general terms, version refers to the changes / revisions. It doesn't generally applies to your Actual but if you look at a Planing cycle, you would keep revising and then reach to a final / approved version. you would rather preserve the multiple versions till it gets approved as it will give you a clear picture of what changes you have done.
If it comes to security, depends on what type of data is there in your application. Accordingly, in the above scenario you might have to provide write capability to only current working version and keep rest of all read only.
I worked for a large automotive organization where they have 7 scenarios & 9 versions (including Approved, Final) and we used to have a script that we run to make a particular scenario read-only.
Hope this information helps
Thanks Amarnath for your reply.
Meaning, they dont go hand in hand in terms of security/access right?
I am not considering the Process Management / Workflow process here
Well it depends as I said.
Case #1: If you have multiple versions for each scenario, you would probably don't want users to have write access on all the versions (That would overwrite any version that is finalized).
If it's just 1 - 1 then both will have the same security. It all depends on what you have in scenario & version
in My case, I have my users across region & across Business functions. So, I have to categorize my security as Business Functions (Not all business functions will have access to All scenarios) & then Region wise security within each business function
It all depends on your security design and application design
I got it.
