Attaching Non-ABAP Objects from a File System 
You have created a transport request.
The transport request has the request status Modifiable.
You have exported the file and saved it to the appropriate file system.
Procedure in Transport Organizer Web UI
In the top half of the Transport Organizer Web UI screen, select the transport request to which you want to attach an object. Then choose the Object List tab page in the lower half of the screen. You can see all objects that have already been attached.
To attach an object to the selected request, choose Attach File Object.
Use the F4 help in the Attach File Object dialog box to select an appropriate application type.
Use the radio buttons to select a file system.
The file you are looking for is either in the file system on your desktop (Client) or in the file system of the CTS server (Server):
Client: Search for the file on your desktop and confirm by choosing OK.
Server: Search the directory defined in the parameter NON_ABAP_WBO_INBOX for the appropriate source system. Select the file in this directory and confirm by choosing OK.
The attached object appears in the object list.

Procedure in Transport Organizer Classic UI (for ABAP systems and dual-stack systems)
Call transaction SE09.
Select Workbench Requests.
Choose Display.
The Transport Organizer: Requests screen is displayed.
Position the cursor on a transport request.
Choose Attach File Object.
The Include File Object in Request <name of request> is displayed.
Select Non-ABAP Object and choose Continue to confirm.
Enter the directory, file name, and attributes of the object and choose Continue to confirm.
Note
You can add any file format to transport requests, including Word and Excel files. You can document your transport requests in this way. This makes sense if you use quality assurance procedures in TMS which you have to provide documents for. You can now use TMS to access these documents at any time and download them to your desktop.
