Hello @Astleitner-Kaiser, Christian
Thank you for reaching out to the Microsoft Q&A platform.
The reason you are not able to select Red Hat for SAP in the Azure free account is that Red Hat for SAP is a premium image that requires a paid subscription. The free Azure account is intended for testing and development purposes only and does not include access to premium images like Red Hat for SAP.
To use Red Hat for SAP in Azure, you will need to sign up for a paid Azure subscription and then purchase the Red Hat for SAP image from the Azure Marketplace. Once you have purchased the image, you can deploy it to your Azure environment and start using it for your SAP workloads.
Alternatively, you can use one of the other supported operating systems for SAP in the Azure free account, such as SUSE Linux Enterprise Server or Ubuntu Server. These operating systems are available for free in the Azure Marketplace and can be used for testing and development purposes in the Azure free account.
