 Business to Administration with the B2A Manager


You use this component to enable electronic data exchange between employers and authorities.

Until now you have exchanged application data from the areas of tax, social insurance, statements, and so on with the responsible authorities on paper or disc. You can use the B2A Manager (Business to Administration Manager) to send and receive data quickly and simply over the Internet.

To do so, you create data records in the relevant area (tax, social insurance, statements, and so on) for the corresponding authority. You can then use the B2A Manager to send and manage these data records.

Or you use the B2A Manager to request certain information from the relevant authority and then subsequently send your data.

The exact process flow for communication with authorities depends on both the area and the country. For more information, see the country-specific documentation.


In order to be able to send data using the B2A Manager, you must first have created the corresponding data records in the relevant area (for example, tax, social insurance).

Implementation Considerations


To see whether specific Customizing settings have to be made for your country for communication with the authorities with the B2A Manager, refer to the country-specific documentation.

If Customizing settings have to be made for your country, refer to the Customizing for Payroll <Country> in the section Communication with Authorities (B2A).


Depending on the authority, the data may have to be encrypted before it is transferred with the B2A Manager. If this is the case, you will require the encryption software of a third-party administrator that is linked to the SAP system using an open interface.

For more information, see Customizing for Payroll <Country> under Start of the navigation path Communication with Authorities (B2A) Next navigation stepSet up Encryption End of the navigation path.


Depending on the country, you can send data from various areas electronically. This includes, for example, the following areas:

  • Tax

  • Social Insurance

  • Statements

You can send the data in various different formats, for example:

  • String

  • XML (eXtensible Markup Language)

Depending on the recipient, the B2A Manager supports various methods of communication and encryption:

  • Methods of communication:

    • E-mail with file attachments

    • HTTPS (Hyper Text Transfer Protocol Secure Sockets)

  • Encryption methods:

    • PEM (Privacy Enhanced Mail)

    • PKCS#7 (Public-Key Cryptography Standards No.7).

As a rule, the method of communication and, if required, the encryption method are determined by the responsible authority and implemented correspondingly by the B2A Manager.

For example, for the data exchange with the receiving offices of health insurers in Germany, data is exchanged per e-mail with the standard PEM encryption.

Transfer per e-mail (e-mail procedure)

The relevant data is sent with the e-mail as a file attachment and is exchanged with the relevant authority.

The advantage of this process is that it is widely used.

Transfer per HTTPS in XML format

The relevant application data is exported to XML and exchanged directly with HTTPS.

Not all authorities support the XML procedure.
