Change message for passing a business key in a Call activity

[ingorichtsmeier]

What should we do?

If a Camunda 7 process model with a call activity passes the business key to the called process, we display this message:

WARNING: Element 'in' cannot be transformed. Business key is not supported in Zeebe.

It's not correct.

The message should be adjusted on different contexts:

• Passing all variables
• Passing some variables
• Passing no variables, but only the businessKey

Why should we do it?

If you already have a process variable called businessKey and propagate all variables, you are fine.

If you pass some variable to your called process, you should take care to include the process variable businessKey as well. In the best case, automatically add the in mapping for the businessKey

Same if you don't map any variables, but pass the businessKey.
