Linking of Applications to Digital Signature

Use

This process describes which steps you need to perform to link an application to the digital signature.

Process

You define a log structure.

The log structure is required to log the signature data for your application and to evaluate the logged data.

The structure must be created in the database for the application that is to be linked to the signature tool.

Example

Structure DSIG_EXAMPLE_SIGN_LOG: Log Structure for Example Implementation
Note
- The structure SIGN_PROT_STRUC must be contained in your log structure as an include. Only the fields in the corresponding metadata tables that are not key fields can be used as additional fields.
- If you need to change a log structure, you must do the following:
  - Retain the existing structure
  - Create and register a new structure
  Otherwise, the system cannot interpret logs correctly that have already been saved.
- A maximum of 250 characters are permitted in a log structure.
You define the following database tables in the Data Dictionary:
- Table for application data, for example, DSIG_BOOKING_EX (Sample Database Table with Application Data)
- Table for metadata for the implementation of your digital signature, for example, DSIG_META_EX
  
  The metadata table is required to store the application-specific information for the signature provided. The metadata table also serves as the basis for the selection of signatures and signature actions (see also Information About Metadata Table).
In the Customizing client in the transaction SIGNA ( Register Application Grouping Element for Dig. Signature), you enter the application to which you want to link the digital signature.

Example

Application: DS_EXAMP

Application description: Signature Tool: Sample Application
You define the signature object for your application using the transaction SIGNO (see also Maintenance of Signature Object for Application (SIGNO)).

Note

You require a transport request for the entries in SIGNA and SIGNO.
You create an entry for your application object in the transaction SLG0 (see also Registering Subobjects for Application Log).
You integrate the programming interface of the signature tool into the program for the application.
You make the Customizing settings for the digital signature. You will find the Customizing settings for the digital signature in the Implementation Guide (IMG) under Cross-Application Components General Application Functions Digital Signature.
You implement the BAdI interfaces IF_EX_DS_AUTHORITY and IF_EX_DS_CONTEXT if required.
You enter the authorization group in the authorization profile (user maintenance).
