在做银行支付单审批时的FIORI功能时，当用户选择一行时，用户点击“审批”来作审批操作，并且在选择需审批的行时，“审批”按钮使能可依据行的审批状态设置，不能操作，或者不能操作。
标准文档，可参考这里。
1.创建BOPF
先需要用CDS创建一人BOPF，可参看这里。这里可依据需要生成对应的BOPF对象，
2.创建一个Actions
打开BOPF后，增加一人动作，比如我这里的SET_APPROVE，我在创建时在HANA STUDIO，及ECLIPS中发现都不能创建成功，我是在SAP GUI中创建的，可能是与我SAP的版本有关，可能是需要ECC752及以上版本才成，
3.创建Determinations
我同样在Eclips里不能创建，我是在SAP GUI里使用事务码BOBX创建的，并且发现ECLIPS里的功能好像没有SAP GUI里的全，所以当发现有不一样时，还是使用SAP GUI查看一下。
创建完成后，有两点要特别注意，不然可能不会触发定义的Determinations.以一是我测试成功的设置以供参考。
- Determinations Cat 需要选择为：Ｔ Transient
- Trigger Conditions 需要选择Request Nodes for Determination，下的带根节点一的****_PROPERTY这项目的Determine这项，
- Evaluation Timepoints,需要选择Before Retrieve .
4.代码
实现Actions的代码，代码在类ZCL_PAYMENT_A_SET_APPROVE-》/BOBF/IF_FRW_ACTION~EXECUTE中实现

5.最后
到这，用这人BOPF对应的CDS创建一个新的消费CDS后，并用之生成FIORI后，就能自动控制审批按钮的可能性，并进行审批了。
