Use

The digital signature ensures that only those users with the appropriate authorization can make any changes. If you use the digital signature, you can fulfil the security requirements that are mentioned in Good Manufacturing Practices (GMP).

Integration

In the SAP System, the digital signature is supported by SSF (Secure Store and Forward). If you use the user signature as a signature method, then you require an external security product that is connected to your SAP System by means of SSF.

Prerequisites

So that you can work with the digital signature, you have to fulfill the prerequisites for the SAP System, as described in Approval with a Digital Signature.

In Customizing Engineering Change Management you make the settings for the digital signature in the section Change type → Approval.

Furthermore, you have to define the processing situations for the digital signature. This is done in the section Change type in the work steps Define change types for the master records and Define change types for the objects.

You can find further information on each individual work step in the IMG for Engineering Change Management, under Approval.

Features

You use the change type of the ECR/ECO to decide which processing situations the digital signature should be checked in.

You can define a signature network for digital signature entry. This signature network is a ssign ed to a chosen change type. When a system status is set for the ECR/ECO or the object management record, the approval process is started according to the chosen signature strategy.

You assign the authorization for the digital signature in the authorization object C_AENR_BGR (change master record - authorization group), activity 73 (Making a digital signature).
