Question
Just throw a new Exception("Xxx")? That gives me Unexpected type: java.lang.Exception. Is there some exception class I can use for this?
Answer
Use throwException(String errorMessage)
For details see: https://qa.pricefx.eu/pricefx-api/groovy/develop/net/pricefx/formulaengine/scripting/PublicGroovyAPI.html#throwException-java.lang.String-
A calculation logic can stop its execution and fail by throwing an exception, for example:
if (api.userEntry("margin") <0)
then api.throwException("I won't let you go bankrupt")
else price=cost+margin
