Things like this are available in SAP Help Files. Please refere them first for basic understanding. I'm quoting the necessary information from help files itself. The path is SAP Library > SAP R/3 Enterprise Application Components > Logisitcs > Sales & Distribution > Billing > Rebate AgreementsRebate AgreementA rebate is a special discount which is paid retroactively to a customer. This discount is based on the customer's sales volume over a specified time period. You define the details of the rebate in a rebate agreement. In the agreement you specify, for examplewho receives the rebate payment on what criteria the rebate is based (customer, customer and material, and so on).how long the rebate agreement is validWithin the rebate agreement you create separate condition records for each product the customer buys. These records specify the rebate amount or percentage for each product. You can also specify a pricing scale so that the customer can earn a better rebate by ordering more. Because rebates are always paid retroactively, the system keeps track of all billing documents (invoices, credit and debit memos) that are relevant for rebate processing. The system can, if you wish, automatically post accruals so that the accumulated value of a rebate is recorded for accounting purposes. A rebate agreement is finally settled when you issue a credit memo to the customer for the accumulated rebate total. You can set up rebates at any level just like pricing. The following rebates have been set up in the standard version of the SAP R/3 system:Rebate based on a material Rebate based on a customer Rebate based on a customer hierarchy Rebate based on a group of materialsPrerequisites for Processing RebatesYou can process rebate agreements when the following prerequisite conditions are met:The sales organization in which you are processing sales orders must be relevant for rebate processing. Your system administrator sets this indicator in Customizing for Sales. The payer must be relevant for rebate processing. In many cases, the payer is the same as the customer. You indicate whether a customer can receive rebates by marking the Rebates field in the Billing view of the customer master record. The billing type (invoice, credit memo, and so on) you are using must be relevant for rebate processing. Your system administrator sets this indicator when defining billing types in Customizing for Sales. 查看原帖>>

Rebate中的accural是什么意思国外交易所给做市商（流动性提供者）的rebate机制主要有哪些？

做市商注入的流动性对交易所的生存往往有决定性的作用。

现代做市商多数是纯量化的高频交易商，在一些竞争不太激烈的地区也会有一些是半自动的交易商。

做市商的利润来源于价差。

如果市场上知情交易者的比例小于一定程度，做市商都是可以稳定获利的，交易所避免手续费则更能提供做市商的吸引力，这样交易所会更倾向于提供而不是消耗流动性，从而有利于整个交易市场。

很多交易所都有专门的“做市商项目”或其他等价的规划用来增强交易所合约（尤其交易量较小）的流动性。

做市商需要满足一系列的做市条件，诸如保证以足够的比例回应交易所客户询价的请求、保证询价的买价和卖价的价差小于某个定值、覆盖足够比例的合约等。

在一段时间后，就可以获得交易所的做市商激励。

不同的交易所做市商激烈通常会有所区别，但多数采用交易和结算手续费折扣形式。

交易所一般给做市商的激励是首先免除交易费用，因为做市商的任何一笔交易都有极大的风险；其次，交易所会给做市商一笔固定的佣金，用来补偿做市商的运营成本和潜在的交易风险。

一般来说，这种佣金的限定条件是做市商要在规定的时间内，提供规定质量的流动性。

这种做市项目目前是国外各家交易所都在开展的，各个交易所都会各尽所能改善包括流动性在内的自身的各种服务。

由于我们仍然是一个脱胎于高度监管缺乏灵活性的市场，这种机制在我国尚未建立。
