If your package version is not appearing in security scanning tools, here are the common reasons and troubleshooting steps:
**Common Reasons:**
1. The package must be either managed-beta or managed-released. For second-generation packages (2GP), the version must be promoted to "Released."
2. Only the last 10 versions of a given package are displayed in the portal.
3. You must use the same Dev Hub or Developer Edition org that was used to create the package.
4. If the package was created declaratively without custom code (e.g., containing only custom objects, fields, reports, etc.), there may not be any scannable content, and it might not appear in the portal.
5. The package version must be visible in the Partner Community under the Publishing → Technologies → Partner Security Portal Solutions tab.
**Troubleshooting Steps:**
1. Ensure the package is either managed-beta or managed-released. For 2GP packages, verify the version has been promoted to "Released."
2. Use the same Dev Hub or Developer Edition org that was used to create the package.
3. Verify that the package is connected to the Partner Community and listed under the appropriate tab in the Partner Security Portal.
4. Remember that only the last 10 versions of a package will appear in the portal.
If these conditions are met and the issue persists, you may need to contact support for further assistance. For more details, you can check the AppExchange Security Review documentation.
