 Making the Access Control List Entries on the Application ServerLocate this document in the navigation structure

Use

When configuring SNC between the AS ABAP and other server components, you must make access control list entries on the application server as indicated below.

Prerequisites

You must know the SNC name used by the communication partner.

Procedure

SNC System Access Control List

Maintain the SNC system access control list for SNC-protected connections between AS ABAP systems.

Using table maintenance, for example, transaction SM30, maintain the SNC system access control list (table SNCSYSACL, view VSNCSYSACL, type=E):

  1. Enter the communication partner's SNC name in the SNC name field. The System ID field is optional. Activate the following as necessary:

Entry for RFC activated

Entry for CPIC activated

Entry for DIAG activated

Entry for certificates activated (if users log on with X.509 client certificates)

Entry for external ID(if users log on using a different external identity)

  1. Save the data.

Extended User Access Control List

Maintain the extended user access control list for SNC-protected connections from RFC client or server programs.

Using table maintenenace, maintain the table USRACLEXT:

  1. Enter the user ID for the corresponding technical user in the User field. Enter an asterisk (*) as a wildcard if any user can log on using this SNC-protected connection.
  2. Enter the communication partner's SNC name in the SNC name field.
  3. If you create several entries for the same user, then enter the appropriate sequence number in the Seq.number field.
  4. Save the data.
Result

The communication partner is allowed access to the application when it connects using SNC.
