Sensitivity Data

I am running a sensitivity analysis with PLE Pluse. I am trying to export the variable data (input and output) for each scenario. For example, I have four input variables that vary randomly from 1-10. I am tracking two output variables. I want to export each multivariate combination and the corresponding outputs for 200 simulations.
I am able to export the output variables, but I can't figure out how to get the corresponding multivariate combinations.
Thanks in advance for your help

Do you have the variables in the save list that you want to export?

Thanks for your reply. Yes. All four input variables are in the Savelist.

Do you have a sample, or can you .zip up the model and supporting files?
The default export should include both the output variables and the input parameters from the .vsc file.

Here is the model. Thanks for giving it a look. If you run the Sensitivity function all of the variables are already selected.

The .zip seems to be missing the .vsc and .lst files?

Sorry about that. Attached are:
1) I4.0_5.0_Experiments.vsc
2) TechFactorExperiment_Input_Output.lst
3) I4.0_Ship Repair_S&F_02152021F-5_Experiment Data.mdl

One problem is that you have a colon in your run name. Colons are illegal file system characters, so that breaks naming the dataset. We'll have to disallow those and a few other characters I guess.
After deleting the colon, I can run and export the sensitivity results to yield:

How do you create that report? That looks like exactly what I am trying to do!

I think I have it! Under the Model tab, Export Dataset. Thank you very much for your assistance. I really appreciate it.
v/r,

Sorry - should have mentioned that explicitly! Glad it's working. We're hoping to roll some capability for visualizing this into native Vensim soon.
