Hi Experts,

Kindly let me know how to get the Transport request details which were not yet imported.

For example:

We have two client in development system 300 and 400, The transports which are created in 300 and imported to 400 (in SCC1).

I need to know the details of transport requests related to 300 which are yet be to moved to 400.

Where can i get these details.
