Short text

Digital Signature (extended)

Use

Since release 4.0A, the SAP system has provided digital signatures, to secure digital documents and business processes. Previously, such digital signatures were only available for selected positions in the SAP system. If a function was to be connected to further applications, the program code had to be extended according to the application. This is very time consuming.

As of release 6.20, a standardized and flexible programming interface is available, with which the digital signature can be connected to any areas in both R/3 systems and other systems, such as APO, CRM, etc. In principle, no changes are made to the existing functions, and the following functions are added:

• The document to be signed is called up by the relevant application and forwarded to the signature tool. When the signature function is called up, the default values in the application decide if the document to be signed should be managed by the application itself or by the signature function.

• For signature strategies with several individual signatures, it is possible to run a verification on executed signatures to check their validity. The verification is independent of whether or not the document is managed by the signature function or the application.

• The user has the option of displaying the document before the signature operation. (However, this is currently only available for .txt type files.)

Effects on Customizing

To implement the digital signature for the required applications, you must perform the following activities in the Customizing, after the upgrade:

• Create the general user settings (see Defining Basis Settings for Digital Signature).

• If you want to use the signatures without a signature strategy, create the corresponding settings (see Specify Signature Method for Approval using Simple Signature).

• If you want to work with signature strategies, you must define authorization groups, individual signatures and a signature strategy.

Further notes

• Digital Signature (for Release 4.0A)

• Digital Signatures (for Release 4.5A)

• Changes to the Digital Signature (for Release 4.6C)
