+# SAP Open Source Security Policy
+
+SAP takes the security of our software products and services seriously, which includes all source code repositories managed through our GitHub organizations, including our primary [SAP](https://github.com/SAP),[SAP-samples](https://github.com/SAP-samples) ,[SAP-docs](https://github.com/SAP-docs) organizations as well as [our other GitHub organizations and projects](https://opensource.sap.com).
+
+If you believe you have found a security vulnerability in any SAP-owned repository, please report it to us as described below.
+
+## Reporting Security Issues
+
+**Please do not report security vulnerabilities through public GitHub issues.**
+
+Instead, please report them via the SAP Trust Center at [https://www.sap.com/about/trust-center/security/incident-management.html](https://www.sap.com/about/trust-center/security/incident-management.html).
+
+If you prefer to submit via email, please send an email to [secure@sap.com](mailto:secure@sap.com). If possible, encrypt your message with our PGP key; please download it from the [SAP Trust Center](https://www.sap.com/keyblock).
+
+Please include the requested information listed below (as much as you can provide) to help us better understand the nature and scope of the possible issue:
+
+  - The repository name or URL
+  - Type of issue (buffer overflow, SQL injection, cross-site scripting, etc.)
+  - Full paths of the source file(s) related to the manifestation of the issue
+  - The location of the affected source code (tag/branch/commit or direct URL)
+  - Any particular configuration required to reproduce the issue
+  - Step-by-step instructions to reproduce the issue
+  - Proof-of-concept or exploit code (if possible)
+  - Impact of the issue, including how an attacker might exploit the issue
+
+This information will help us triage your report more quickly.
+
+## Preferred Languages
+
+We prefer all communications to be in English.
+
+## Disclosure Guidelines
+
+We like to ask you to follow the [Disclosure Guidelines for SAP Security Advisories](https://wiki.scn.sap.com/wiki/display/PSR/Disclosure+Guidelines+for+SAP+Security+Advisories).
+
+## SAP Internal Response Process
+
+As an SAP employee, please check our internal open source security response process ([go/oss-security-response](https://go.sap.corp/oss-security-response)) for further details on how to handle security incidents.

+> **Heads-up on a screenshot typo in the upstream tutorial.** A couple of screenshots in the tutorial show the artifact name as `V_INTERATION` (missing the second **C**). The correct name — used in the surrounding text, your CDS file, and every later step — is **`V_INTERACTION`**. When you create the Calculation View artifact, type `V_INTERACTION` regardless of what the screenshot shows. (Tracked upstream; this note will be removed once the screenshots are refreshed.)
