How to link Worker Assignment and Work Employment Contract in autocomplete?

Summary:

Hi everybody,

We are trying to make an autocomplete rule that links these two business objects.

For example: Is it possible to set null values in different fields in Worker Assignment section based on the contract type of the worker which is in Employment Contracts?

From which business object should I create the rule and what kind of business rule type should I choose in order to avoid null pointers?

is it possible to do these autocomplete? Is it feasible with autocomplete rules?

Thank you in advance.
