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

One time customer / vendor accounts in SAP means they are account 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 account 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.

What is difference between vendor and one time vendor and what purpose to create one time vendor and what are required field to fill in vendor and one time vendor? - Navas

One time vendors are those who are not frequent vendors. Company will be using those vendors very rarely, maybe once in a life time.  SAP is giving a special category for those type of vendors. Normal vendors will have separate Master Data which will have their address, country, bank account, terms of payment, payment methods, etc. 

Whereas there will not be such records kept in Master data for those one time vendors. This way you will reduce the data base size. There will be one vendor master record named as one time vendors and will have the check box ticked while creating this record. Country field is mandatory when creating a normal vendor master (sap standard) whereas it will not be in case of one time vendor. 

When you post a document to this vendor (One time vendor), it will prompt you to fill the name address and all the required fields at the document level.
