信贷额度的组成：假如某客户信用限额1万；开出销售订单时锁定1万；一旦发货1万，销售订单1万限额释放，变成发货锁定限额1万。一旦开票，发货1万限额释放，应收锁定1万限额。清帐成功，应收释放1万。信用限额又回到1万了，如此循环。
未清订单价值：未清订单价值是所有未交货的订单条目的价值；未清订单的价值是基于已确认数量的（已
确认数量乘以信用价格=订单的未清订单价值）；因信用检查已经被锁住的订单不包含已确认的数量；
只要锁还在，未清订单价值就不会增加
未清交货价值：未清交货价值是所有尚未出具发票的交货条目的价值；做了交货装载未做交货确认（客
户收货）。
未清出具发票价值：未清出具发票价值是所有尚未传输到会计的出具发票条目的价值
来自特殊总账事务的预收款：如果它们与信用限额相关（例如，付款），则会从特殊承付款转移到总承
付款；系统基于付款者更新价值；

以上部分为标准信贷管理的配置和说明，下面就说说临时信贷的东西，临时信贷不在SAP标准范围了，这是根据业务需要整出来为一些信用超额的用户实行的特殊管理。
一张临时授信表，对应到客户级别，订单级别，信贷范围级别，且每条授信数据都是有有效期。
逻辑说明：在信用检查的出口中计算客户的临时授信等数据，并参与到标准的信用计算中，最终对于结果给出标准的信贷返回值。
