Workflow, how to link many address Postal Code to specify state?
For example:
In the Lead page is postal code and I will put there manualy postal Code 00-000 it would like system automaticly choose state number one (Enum List), In another case I will write 99-000 system assign state number three and etc.

How I can set many parameters for one State in the Workflow?

I will do it with Formula. Code is the same, but workflow runs after record saved, Formula in Entity Manager - before. But if you want, you can use the same code in Workflow action Update Target Record. Also you can add a condition if postalCode was changed

https://www.espocrm.com/documentation/administration/formula/

it has to be something like

ifThen(postalCode == "00-000", state="the key of option 1");
ifThen(postalCode == "99-000", state="the key of option 3");

postalCode and state - field names of entity, you could check it in Entity Manager or select in attributes
the key of option - check in Entity Manager as well. It has to be a key, not the translation.
