Hello @Ram Kumar Cheekoti Thank you for reaching out to us on Microsoft Q&A platform. Sorry for the inconvenience this must have caused you!
Answering this from Cost Management perspective:
I see that the cost data is not showing up for the disks, it is likely because the disks are not currently being billed.Azure Cost Management only shows cost details for resources that are currently being billed. If the disks are not attached to a VM and are not being used, they may not be incurring any charges and therefore will not show up in the cost details.
To confirm whether the disks are being billed or not, you can check the Azure portal. Go to the "Disks" section and look for the disks that are not attached to a VM. Check the "Status" column to see if the disks are "Unattached" or "Attached". If the disks are "Unattached", they are not currently being billed.
If you want to remove the disks to avoid future charges, you can delete them from the Azure portal. However, please note that deleting a disk will permanently remove all data stored on the disk, so be sure to back up any important data before deleting the disk.
From Azure Advisor lens: The issue needs to be investigated further to understand why it came as an Advisor cost recommendation and failing to show the data.
FYI: Azure Advisor support is included in the Basic Support Plan without any charge.
