建workflow的时候提示Prefix …

输入事务“SWDD”进入工作流编辑界面

点击保存的时候，提示：

Prefix number: entry missing for system DSE client 800

然后点进去查看具体信息时：

Prefix number: entry missing for system DSE client 800

Message no. 5W023

Diagnosis

Tasks, rules, and workflow definitions require an ID that is unique throughout all systems and clients. In this way, you can ensure that you can transport these objects from one system into another at any time (without restrictions). From a technical point of view, the uniqueness of the ID is ensured by what is known as a "prefix number". You can define a separate prefix number for every system and every client in table T78NR.

System Response

If a prefix number is not defined in the client in which you are currently working, it is not possible to maintain (maintenance terminates).

Procedure

Maintain table T78NR in Customizing, and create an entry for the system in question and the current client.

最主要的一句是：

You can define a separate prefix number for every system and every client in table T78NR.

那就输入se16n

在打开库表 T78NR前输入&sap_edit并回车，激活编辑状态

然后在里面把你的client添加进去就行了

其中227是随便输入的，反正系统目前还没有227，DSE是系统标识

800是我目前的client，

保存之后，再创建workflow的时候就不提示了。

这种事仅限于在自己的练习系统中，到项目里了，这么干……要么没权限，要么得卷铺盖走人了……
