Signature Methods

Use

You can specify whether you want to execute the signature with a system signature (with user and password) or with an additional security product.

Prerequisites

You specify which signature method you use in Customizing for each signature object type, that is, for all simple signatures for objects of each type, and for each signature strategy.

Features

The SAP system distinguishes between the following signature methods:

• System signature with authorization by user ID and password

  Here, you do not require an external security product. The signatory identifies himself or herself with his or her user ID and password, just as when logging on to a system. The SAP system then provides the digital signature, whereby the name and user ID are part of the signed document.

• User signature with verification

  Here, you do require an external security product. The user provides the digital signature using his or her own private key and the signature provided is checked immediately to verify its authenticity.

• User signature without verification

  Here, you do require an external security product. You can use this signature method for test purposes only and not in a production system. The user provides his or her signature as described in the previous method, however, the automatic verification is deactivated.
