$$ Variables

A structure is assigned!

If you do not want to store exactly one (text) value in a variable, we recommend using the variable instantiated with $$. The difference to the $$ variable is that whole (tree) structures can be stored in the $$ variable.

In the following example, the first position is stored in a variable and then assigned the DeliveryDate on the variable.

Note: $$ variables are also called after instantiating with only one $!
Note: Variables can only be reset using the ClearVariable mapping function, since a rule with an empty string is not executed.!
