有些客户的销售不是长期性的，是临时性的，没必要为他们创建主数据，则共用一个**，这种隶属于one-time account组 这种**组会设定为只需要输入帐户共同性的数据，比如区域，统御科目，币种，而类似银行数据则会隐藏掉。

看看SAP notes描述：

What is the treatment of one time customer / vendor accounts in SAP?

 One time customer / vendor accounts in SAP means they are ac__count groups for customer/vendor and where in only the general data of the customer / vendor are stored instead of maintaining the bank data and other company code data that are relevant for other ac__count groups which are useful for long run purposes.

 As you know everything that is entered in SAP is saved in some TABLE. Now the customer & vendor__ master is such a table which holds vast amount of data.

The business secenario where the vendor or customer which are being in system only for 1 transaction, it is not advisable to have all the data maintained in main__ master.

Therefore SAP has provided with the feature of One time vendor / customer wherein in the document entry stage only you have to enter the name, addres and other details of the vendor/customer.

The data, as far as I know” remains at doc level and does not goes to__ master tables.
