Hi Brijesh:
I followed up with Todd Parker from the SAP Cloud Partner Solutions team. He noted that the content you are trying to access requires a learning hub subscription. This content is not paid for through the partner program fees. Partners do have access to all content on sappartneredge.com at no addiotional cost.
If you need help establishing a subscription to the learning hub, please let me know and I will share your contact details with Todd so that he can provide further assistance.
Debbie.
