Go to transaction code SE01 and now you can filter the requests by “Request Type” like shown below

Customizing Requests;

Change of customizing settings are recorded in “Customizing Requests”.

Customizing requests contain changes to “Client Depending Tables”.

When we release the requests , the current status of the recorded settings are
exported and can be transport to other SAP systems.

When we create a customizing request, the transport target system automatically
assigned by the transport layer configuration of SAP STMS system.

Workbench Requests ;

If going to change “ABAP workbench objects” then “Workbench Requests” recorded
by the SAP system.

Workbench requests contain changes to “Client Independent Tables” and related to the
Development tasks.
