E-mail Guidelines

SAP helps protect your sensitive company information and ensures compliance to the pertinent data protection regulations that may apply to all our customers and partners (e.g. GDPR). However, it is your responsibility to ensure only the right people have permission to transact on behalf of your company, and only with the authorizations required to complete their tasks.

valid e-mail address is mandatory for SAP Universal ID and all S-user IDs.

SAP is assisting customers and partners in their responsibility for users administration by introducing compliance checks on e-mail addresses.

Every existing and newly created S-user will be checked for compliance with the following rules:

Important Information:

SAP will neither disable, deactivate nor delete any of these highlighted users.

SAP will only highlight users with non-compliant e-mail addresses in the User Management application. 

Technical Communication Users are explicitly excluded from these rules. 

Maintain Allowed Company Domains

Super and Cloud Administrators are required to maintain an official list of their company's e-mail domains, ensuring that S-users match their corporate e-mail address.

  • Cloud and Super Administrators can access the application via the direct link Maintain E-mail Domain application, or from the User Management application (Manage Services >> Maintain E-mail Domain application). 
  • Cloud and Super Administrators can add, and regularly maintain, all official e-mail domains that represent a company, subsidiaries, and/or CCoE. 
  • User creation is not possible if no domain or an incorrect domain is stored in the Maintain E-mail Domain application.
  • Only e-mail domains used for corporations (e.g. are compliant with the Identity and User Management Policy.
  • Public or free e-mail sites (e.g. are still allowed and are highlighted and treated as a non-compliant domain.

A minimum of one domain is required.  For your own security, please do not add domains that are not associated with your company.

The information will be used to validate S-users' e-mail addresses - those that do not comply will be highlighted in the User List, User Profile and Contact Detail Page of the User Management application.

In future, if a new S-user ID is requested or an existing S-user changes their e-mail address, only those that successfully match corporate domains will be allowed, while others will be rejected. Super and Cloud Administrators may choose to override if necessary. Nevertheless, Super and Cloud Administrators will still be allowed to use public or free e-mail sites after entering an acceptable reason in the note field either in the user creation form or in the users contact detail page.

One example of improved compliance is that SAP ONE Support Launchpad notifications will then only be sent to corporate e-mail domains.

Blocking of Shared E-mail Addresses

To enhance security and improve data quality, we have introduced governance for e-mail addresses used by all new SAP Universal IDs and S-users.

SAP Universal IDs are owned by a person with a unique e-mail address (1 person = 1 user). Therefore, we are now blocking e-mail addresses commonly shared by groups.

For example, is not a personal, unique e-mail address and cannot be used to create an SAP Universal ID. This restriction has also been added to the User Management application in the SAP ONE Support Launchpad.

E-mail Duplicate Check

We have introduced a duplicate check for every newly created S-user, within the same customer number, based on a unique and individual e-mail address.

S-user account creation with duplicate e-mail addresses is no longer supported for data quality, security, and compliance reasons. Additionally, cleansing of e-mail duplicates has already led to significantly faster S-user creation.
