Can the selectbox variable map to reference field in incident

[DSV22]

HI

I have choice variable (Application Affected) in my Record producer, and I need to map the field to Category and Service Fields in the Incident form 

The incident form Service should be reference field, and a user should be able to search for the application if reporting from the native view.

I have tried with script in RP

current.category = producer.application_affected.getDisplayValue();

current.subcategory = producer.issue_type.getDisplayValue();

current.cmdb_ci_service.setDisplayValue(producer.application_affected);

Is this possible can anyone help me to achieve this

Try using the Map to field option on the variable first to map Application Affected to Service on the incident form.  Application Affected should be a reference variable.  If this must be a choice variable, set the value of each choice (not the label) to the sys_id of a record on the cmdb_ci_service table, then if it doesn't map due to the type mismatch, in your script you can use

current.cmdb_ci_serivce = producer.application_affected;

I'm not sure what you're trying to do with category and subcategory in the script.  You can just have 2 select box variables that map to these fields.
