Thank you!  I ended up adding the following script to a BR on the source table:

 

(function executeRule(current, previous /*null when async*/) {

    // Assuming 'u_source_table_field' is the field in the current table that triggers the update
    // And 'target_variable_name' is the variable in the RITM to be updated
    if (current.u_package_description.changes() || current.u_requested_item.changes()) {
        var grRITM = new GlideRecord('sc_req_item');
           grRITM.addQuery('sys_id', current.u_requested_item);
        grRITM.query();
        if (grRITM.next()) {
            grRITM.variables.package_description = current.u_package_description
            grRITM.update();
        }
    }

})(current, previous);
