Is the following an incorrect use of a!save(): a!save(save!value, if(local!variable, "yes", "no"))?

The statement regarding the use of a!save() is indeed true. The a!save() function is used to create a context-specific saving mechanism in Appian, allowing you to save the value of a variable conditionally based on a certain rule or condition.

In this case, the syntax of the a!save() function is not being incorrectly used. The way it's structured here, with save!value as the target for saving and the if() function determining the value to save based on the condition of local!variable, is entirely appropriate. The if() function will return "yes" if local!variable is true, and "no" if it is false, both of which are valid outputs that can be saved to save!value.

Therefore, stating that this is an incorrect use of a!save() is true. The expression is syntactically correct and will function properly as intended per Appian's design capabilities.
