Which way is usable replacing with the the WorkInProgress and TimeInSystem Tracked Variables in 22up1?

Use a Content chart (Composite WIP) or a Staytime chart (Composite Staytime) in the dashboard.

Alternatively, you can add your own tracked variables and set them however you like to track whatever you want.

The way the existing WorkInProgress and TimeInSystem tracked variables worked was often not what the user expected. Especially if the user was using combiners, separators, or Process Flow.

Here are a couple examples of confusion caused by these default tracked variables:

@Phil BoBo Thanks for your detail and kind explanation. I had used two variables but I have not experienced the issue like the linked. Anyway I found your reply lately. Thanks again.

I´ve mentioned that the "OnSimulationStart" event is part of the objects (e.g. Fixed Resources). Wouldn´t it make sense to add this also to the Model Triggers?

The release notes mention "coroutines" several times, but I couldn't find anything about them in the documentation. Is there documentation somewhere about what coroutines are and how to use them?

@Jeremy R See Coroutines and the Await Statement. I'll update the release notes to point at this section.

@Matthew Gillespie and @Phil BoBo

I have felt some things whenever the upgraded version released and we read the manual. We can't understand all things to be upgraded like you developers. And me not to use English have some difficulties to understand them and make them for our customers to find them when they use.

We need some more detail explanation like above linked and added examples about upgraded and newly added features.

That is what we understand more your efforts to have developed them and will use them more powerfully.

Anyway thanks again.
