编码生成随机数

星空企业版和标准版没有生成随机码的功能，但是可以单据编码的编码规则可以使用文本字段，这样我们生成一个随机数放入到文本字段中，在更改编码规则拼接这个文本字段，就可以做到随机数的功能。
首先，现在对应单据上面添加一个文本字段，我放入到单据头中

上代码

# 引入clr运行库

clr.AddReference("System.Data")
clr.AddReference("Kingdee.BOS")

# 定义字符串中包含的字符集
random = Random()
chars = ["q","w","e","r","t","y","u","i","o","p","l","k","j","h","g","f","d","s","a","z","x","c","v","b","n","m","1","2","3","4","5","6",

# 获取当前单据的Fid
def gain_fid():
    fid = this.View.BillBusinessInfo.GetForm().Id
    return fid


# 根据Fid 找到表名
def Fid_tableName(fid):
    sql = (
        "/*dialect*/select FKERNELXML.query('//HeadEntity/TableName').value('(TableName)[1]','varchar(max)') as '单据头表名'from  T_META_OBJECTTYPE where FID='{0}'"
    ).format(fid)
    ds = DBUtils.ExecuteDataSet(this.Context, sql)
    tab = ds.Tables[0]
    tabName = ""
    for dr in tab.Rows:
        tabName = dr["单据头表名"]
    return tabName


# 生成指定长度的随机字符串
def generate_random_string(length):
    str1 = ""
    for i in range(length):
        XuHao = random.Next(0, 62)
        str1 = str1 + chars[XuHao]
    return str1


#  查询是否生成该随机数  现在是表名固定的，需要做到可以查询到根据不同单据类型可以查询到不同的表名
def ChaXunSql(suiJi):
    fid = gain_fid()
    tabName = Fid_tableName(fid)
    sql = ("SELECT F_XWWP_SuiJiShu from {1} where F_XWWP_SuiJiShu='{0}' ").format(
        suiJi, tabName
    )
    ds = DBUtils.ExecuteDataSet(this.Context, sql)
    tab = ds.Tables[0]
    return tab


# 在创建阶段将随机数赋值进去 做个循环，判断是否随机数生成重复
def AfterCreateNewData(e):
    billObj = this.Model.DataObject

    while 1 > 0:
        i = 1
        i = i + 1
        str2 = generate_random_string(10)
        tab = ChaXunSql(str2)
        if tab.Rows.Count <= 0:
            this.View.Model.SetValue("F_XWWP_SuiJiShu", str2)
            return
        if i > 1000:
            return

将代码放入到表单插件里面，注册python脚本，复制进去就好了，这样随机数就会生成在随机数文本框中
效果

最后到编码规则里面更改就可以了

最终效果

复制单据也不会影响随机数生成
