Functionality
You use this method to change aliases for thebusiness partner.

Notes
This method processes data for each business partner.
A preprocessing run takes place before the data is changed:

• A check is performed to determine whether the business partner with a
valid business partner number is available for processing.

• A simple exclusive lock is activated.

This prevents other users from changing the business partner that iscurrently being processed until either the method TransactionCommitor TransactionRollback for the Business Object BapiServiceis executed. The authorized user can access the same business partnerrepeatedly.
The alias is not written to the database until the methodTransactionCommit for the Business Object BapiService hasbeen called.

Authorizations
You can make settings for business partner authorization objects to bechecked in Customizing for the SAP Business Partner under BusinessPartner-> Basic Settings-> Authorization Management.

Customer Enhancements

For more information on customer enhancements, see the SAP Library underCross-Application Components -> Business Framework Architecture(CA-BFA) -> Further Development, Modifications -> Customer Enhancementand Modification of BAPIs -> Customer Enhancement of BAPIs.

This parameter serves as a data container. In the parameter you cantransfer additional data to the method that was not considered at theinterface.
The data is transferred in a table. The format for the individual datarecords for this table is determined by the structure BAPIPAREX. Thiscontains several data record fields (VALUEPART1, VALUEPART2, ...) aswell as a field for the name of an internal structure created by thecustomer (STRUCTURE). As the data for each data record is writtenpiecewise, one after the other, in the available data record fields, aninternal structure is required in order to interpret the data.
In the event that a customer wants to add additional fields to an SAPdatabase table, BAPI table extensions are particularly well suited asinternal structures.
You will find more detailed information on the various customerenhancement options, and the internal structures to be used in eachcase, in the document Customer Enhancement and Modification of BAPIs
in the SAP Library under Enhancements, Modifications ...(CA-BFA).
The data for the parameter is transferred to the methods Validateand Transferextensionin for the Business Add-Ins (BAdIs).
