If you are holding a grandfathered certificate with the code C_THR81_1405 or/and C_THR88_1408 then you are eligible to take the delta exams D_THR81_1505, D_THR88_1508.
The certificates C_THR81_1405, C_THR88_1408 are valid prerequisite certificates for the related delta exams.
All grandfathered certificates are available in our Certification Hub with the S-User ID (Person ID) you provided when you registered for the data transfer.
If you cannot book the delta exam the problem might be that your Certification Hub subscription is bound to a different Person ID than the one the prerequisite exam is related to.
In this case please write an email with the subject text “[CertHub booking issue]” to Credential-Manager@sap.com. Please provide your current Person ID and the exam you’d like to book.
Please note: If you changed jobs and now work for a different company since you subscribed to the Certification Hub you cannot use the remaining contingent of your cloud subscription. This is because your cloud subscription is linked to your company’s S-User.
