Hi @Merin Mary
Thank you for reaching us!
If I understand correctly, you have a subscription in Tenant A and now I would like to access the Tenant A subscription from tenant B if this is the case it is not possible to access a subscription in Tenant A from Tenant B. Subscriptions are tied to their respective tenants, and you cannot directly access a subscription in Tenant A from Tenant B.
If my understanding is incorrect, please explain in detailed what you are trying to achieve and what steps you have taken.
