Logistic Applications


As of Release 4.0A, you can specify that a user must execute a digital signature to be able to carry out particular business transactions in the R/3 System.

The digital signature enables you to meet the security requirements stipulated in the Good Manufacturing Practices (GMP) with regard to the execution of these transactions. The digital signature ensures that:

In Release 4.0A, the digital signature has been implemented for the following transactions:

(Converting an engineering change request into an engineering change order and changing the status from "Order incomplete" to "Order complete")

Technical Prerequisites

The digital signature has been implemented in the R/3 System using Secure Store and Forward (SSF). SSF enables the linking of various security products supporting different identification procedures. In Release 4.0A however, the above mentioned applications only support the identification using chip cards. For more information on SSF as well as on how to install it, see release note Using External Security Products.

Activating the "Digital signature" function

To specify that a digital signature is required for the above mentioned transactions, you must activate the function in the relevant application. Proceed as follows:

Authorizations for digital signatures

For users to be able to execute a digital signature, you must assign them the authorizations listed in the table below:

Electronic signature for AuthObject Field Value
Worksteps in PI sheet C_CRPI_BER Activity 73
Invalid values in the PI sheet C_CRPI_BER Activity 73
Approving batch records M_MATE_CHP Activity 73
Insp.results recording for insp. lot Q_MATERIAL QMATMODUS M
Usage decision for inspection lot Q_MATERIAL QMATMODUS L
Processing change orders C_AENR_BGR Activity 73
Releasing change orders C_AENR_BGR Activity 73

Processing digital signatures

The procedure for executing a digital signature is identical for all above mentioned transactions:

1. You choose the function that is used to carry out the corresponding transaction in the R/3 System.
2. Based on the settings you have made, the system recognizes that a digital signature is required and branches to the dialog box for signature execution.
3. You insert your chip card in the card reader and enter your user name and password in the dialog box if required.
4. If you want to enter a comment for your signature, choose Create comment. If not, choose Continue.
A comment must be entered for some transactions (see the Comment req. indicator in the dialog box). If this is the case, the system takes you to the text editor irrespective of the function you choose.
5. The system checks:
6. Depending on the results of these checks, processing is continued as follows:
The function is canceled after the third unsuccessful attempt.
7. If the signature requires a comment or if you have chosen Create comment in step 4, you now enter your comment. The text is saved when you leave the editor.
8. You can now continue the function you have called in step 1. When you save the processed object, the signature is also saved.

Displaying digital signatures

You can display the signatures that have been executed for an inspection lot, engineering change order, PI sheet, or batch record, from within the corresponding object. You can find the display function in the following menus:

Finding electronic signatures

For evaluation purposes, you can find digital signatures for the following search criteria:

The system generates a list of objects for which digital signatures have been executed. From this list, you can jump to the objects and display all signatures executed for it.

You can find the search function in the following menus:

Notes on archiving

Note that at present digital signatures are not included when you archive inspection lots, engineering change orders, and PI sheets.

Change system parameters in customizing

To specify that a digital signature is required for the above mentioned transactions, you must activate it in the following Customizing settings (see Activating the digital signature above):

Set up control recipe destinations
Material authorization groups in QM
Define change types for change master records
