Populate subject person field in the description of HR task template

[ArpitaVK]

I have a requirement to autopopulate the {subject person} in the description of HR task template. The subject person refers to another table. The description is like '<some text {subject person} some text>'. I have to only change the subject person dynamically for that particular HR task template. How to write BR for the same?

This works too: ${parent.ref_sn_hr_core_case.subject_person.name}

Hi @ArpitaVK 

Create a Before Insert Business Rule on the HR Task (sn_hr_core_task) table.
In the script, check if the record uses your specific HR Task Template.
If yes, replace {subject person} in the description with the actual subject_person.getDisplayValue().

Example snippet:

if (current.template.name == 'Onboarding Checklist' && current.description) {
   var person = current.subject_person.getDisplayValue();
   current.description = current.description.replace(/\{subject person\}/gi, person);
}

✅ Runs only for that template
✅ Dynamically inserts the subject person’s name in the description before saving
