Error Messages after changing resource calendar

[Matze]

Hello,

I have some plans with tasks an resources.
After insert of holidays in the resource calendar there come a lot of error
messages:
"Ressource ist außerhalb der ursprünglichen Termine von Vorgang ......".

If a want to change later the duration of a task there comes the message
again.

Can someone help me?

Hi Matze,

You selected fixed uration as the task type.
The holidays of the resources now cause this "fixed" duration to change.
Don't you agree that is is normal for MS Project to warn you?
If you select Fixed units or fixed work as task type this message will not
appear.

Gruesse,

Hi Jan,

thanks for your help.

Dependent to our environment (special planing tool) is it no possible for us
to change the task type from "fixed duration" to an other. We have to find a
solution without changing the type.

Greeting Matze

Hi Matze,

But what is the solution you want?
Do you want to avoid the changing of the duration of do you want the
messages to not appear?
I can think of solutions for both but they are different.
