Create Attachment showing in Dev client but unavailable in Quality client

Hi,

In Development Client, in Change Travel Expense Report, I can create Attachment and attach expense receipts scan copies. But when I try attaching the receipts in Quality client, the create Attachment option is not available.

I thought this will be authorization issue, but even when I use Super User authorization, it does not work.

Attaching the screen shots.

In Development Client

In Quality Client

Please suggest, what may be the reason.
