I have tried adding the file upload feature to my CDS i'm using Odata V2 like you and i can't even choose the file that i can upload it's like my field where i can upload the file is disabled when it is not.

I have checked everything and tried everything i even went so far by disabling the virus scan but always the same issue.
I started to wonder if it is even possible to implement the file upload feature for an Odata V2.

Hello again i was able to use the file upload feature only on Odata v4 and i did it by following the below links

Start by following this blog for implemting the file upload feature

https://community.sap.com/t5/technology-blogs-by-sap/streams-in-rap-uploading-pdf-excel-and-other-fi...

In OData V4 we have to enable the draft or we will not be able to view the create button, so enable the draft by following this blog

https://community.sap.com/t5/application-development-and-automation-blog-posts/understanding-and-usi...

After applying everything try and check if it work, if it doesn't and you face this error 
Virus scan profile /IWBEP/V4/ODATA_UPLOAD is not active
Refer to this Note 3010735 - F4111 - Virus scan profile /IWBEP/V4/ODATA_UPLOAD is not active

Best of luck everyone.

I'm facing the same problem, did you manage to solve it?

Try spelling the value of annotation @Semantics.largeObject.mimeType to 'Mimetype'. Exactly like the field name.

See if that helps.

Cheers!

Still the same error .

Its possible to create this method by another way ?

[dhegde]

at least it is not requried as per the help documentation. Adding these annotations should suffice.

I tried it on BTP Trial ABAP Environment and it works. Here is the example
