Add BR Trigger conditions properly something like - impact changes || priority changes

Refer sample logic below:

//sample logic
var grST = new GlideRecord('child table') // childtablename
grST.addQuery('parent',current.sys_id); // add your related list condition, added parent as example.
grST.query();
while(grST.next())
{
grST.priority = current.priority // map directly if backend values are same else do an if check and map it.
grST.impact = current.impact //map directly if backend values are same else do an if check and map it.
grST.update();
