Use

You carry out this procedure in the PI sheet if, for some reason, you want to cancel a signature process that has been started by somebody else and withdraw the signatures executed so far.

Prerequisites

  • If you use the user signature as your signature method , you need an external security product that is linked to your SAP System using the basis component Secure Store and Forward (SSF) .

  • In Customizing for the control recipe destination, it has been specified that you must execute a digital signature when you sign a process step in the PI sheet.

  • A signature strategy has been assigned to the control recipe destination or the process instruction, that is, several individual signatures must be executed.

  • The following authorizations have been assigned to you:

  • The authorization to execute digital signatures in PI sheets (authorization object C_CRPI_BER)

  • If required, a maintenance authorization for the PI sheet, which is defined in the process instruction (authorization object C_CRPI_BER)

  • The authorization for the relevant individual signature (authorization object C_SIGN_BGR)

  • You have not yet executed a signature for the object you have selected.

Procedure

  1. Enter your user name as the signature.

In ABAP list-based PI sheets, choose the icon for the digital signature instead.

The dialog box appears in which you can execute digital signatures.

  1. In the Signatures to be executed section, select the individual signature assigned to your authorization group.

  2. ( )

    When you cancel a signature process, the system does not save any comments. For this reason, do not enter a text.

  3. If you use the user signature as your signature method , make sure that the system can access your Personal Security Environment (PSE) . How you do this depends on your security product. If you use a smart card reader, for example, insert your smart card in the reader.

  1. Enter your user ID and password and choose ( ) Signature process .

The system checks:

  • Whether you are authorized to execute the individual signature

  • Whether your entries match the data in your user master record

  • Whether your entries match the data in your PSE (if you use user signatures)

Depending on the results of these checks, processing is continued as follows:

  • If you do not have the required authorization or your entries are invalid, or if the system cannot access your PSE, the system takes you back to the dialog box where you can enter your data again (steps 2 to 4).

The function is canceled after a certain number of unsuccessful attempts that can be defined specifically for each customer. The user is locked and can no longer execute digital signatures. If a system signature was used, the user is even locked against logging on to the system again.

  • If your entries are correct, the signature process is canceled and you return to the PI sheet.

Result

All signatures executed during the signature process are withdrawn. This transaction is documented in the log for the digital signature.
