Maintain Basis Settings for the Digital Signature

To execute a

digital signature in the PI sheet, you must first make a couple of settings.

The basis application component Secure Store and Forward (SSF) is used to realize digital signatures in the SAP System. This section tells you how to make the following settings:

Which settings you make here depends on the signature method you use (see Specify Signature Method for Approval Using Simple Signature and Define Signature Strategies)
When a signature is executed, the system copies the signatory name together with the local time according to the signatory's personal time zone to the signed document.

Caution

All users can maintain their address data and defaults by choosing System -> User profile -> Own data. The general user settings along with the SSF settings for the user are part of this data. Therefore if you use digital signatures, do not assign the authorization to maintain own data to all users.

Requirements

If you use the user signature as your signature method, you need an external security product that islinked to your SAP System by way of SSF.
Note that you should not store the users' Personal Security Environment (PSE) in a file system but rather, for example, on a smart card. The PSE software does not comply with legal requirements for digital signatures.

Standard Settings

The SSF settings for the system signature are contained in the standard system.
