纷享逍客根据发货单产品数量自动生成产品编码并逐一更新

已知：7个产品编码字段：【"cpxlh01__c", "cpxlh02__c", "cpxlh03__c", "cpxlh04__c", "cpxlh05__c", "cpxlh06__c", "cpxlh07__c"】
需求：当产品数量小于等于7时，依次按照产品数量逐一更新至第一个，第二个，，，第N个字段。当产品数量大于7时，第七个字段存储：{ 第七个到第N个数据 } 一个用英文分号【;】进行分隔的拼接字符串。
Groovy代码：

import java.util.List;
String generateProductSerialNumber(String productSn, String deliverySn, int index) {
	// 格式化数字,整数前自动补零
    String serialNumber = String.format("%02d", index);
    return productSn + deliverySn.substring(deliverySn.lastIndexOf("_") + 1) + serialNumber;
}

String generateExtraFields(String productSn, String deliverySn, int startIdx, int endIdx, List<String> extraFields) {
    if (startIdx <= endIdx) {
        extraFields.add(generateProductSerialNumber(productSn, deliverySn, startIdx));
        generateExtraFields(productSn, deliverySn, startIdx + 1, endIdx, extraFields);
    }
    return String.join(';', extraFields);
}

void updateFieldsBasedOnProductDataCount(int productDataCount) {
    String fieldPrefix = "cpxlh";
    String deliverySn = context.data['name'];
    List productList = context.details['DeliveryNoteProductObj'] as List;
    updateFields(productDataCount, fieldPrefix, deliverySn, 1, 1, productList, 1);
}

void updateFields(int productDataCount, String fieldPrefix, String deliverySn, int i, int j, List productList, int updateCounter) {
    if (i <= productDataCount) {
        def product = productList.get(i - 1) as Map
        String productSn = product['field_0641A__c'] as String;
        int quantity = product['delivery_num'] as int;

                if (fieldName != "${fieldPrefix}07__c") {
                    product[fieldName] = generateProductSerialNumber(productSn, deliverySn, j);

                }
                j++;
