Dear all,
I get a warning when I try to use data from an excel file:
WARNING: Simulation starts before first time for exogenous variable - "X"
WARNING: Exogenous variable - "X" - in range at time 1
Can I avoid such warnings?
thx

Yes. Click Tools->Options->Settings and click "Suppress" for the "Show warnings" setting.

It's good to turn them back on from time to time to be sure that you're not missing anything important.

you can also target specific warnings by using control keywords in a .cin file - see the section "Constant Input Files" in Chapter 8 of the Reference Manual.

I try to avoid turning warnings off, unless I have not found some way to modify the model so as to avoid the warning.
I always declare a variable as supplementary to avoid a warning, use a dimensionless parameter with look ups. With warnings like ' the value has changed with initialisation' I try to change the structure of the model. I have always found a solution to avoid any warnings, so if I press the Ctrl u key, I expect to have no warnings at all if I have made some changes to my model. I do not understand people who leave plenty of warnings that could be easily suppressed when one runs their models. A warning warns and it is better to understand why and to make modifications if possible.
There are a multitude of possibilities to make errors in a model both conceptual or technical and turning of a possible information easy to obtain about the model is to my opinion unclever.
Regards.
