You can change only one record with additional data for each businesspartner.
A preprocessing run takes place before the data is changed:

available for processing.

• A simple exclusive lock is activated.

or TransactionRollback for the Business ObjectBapiService is executed. The authorized user can access the samebusiness partner repeatedly.
The additional data is not written to the database until the methodTransactionCommit for the Business Object BapiService hasbeen called.
