File Upload option not showing in SAP RAP Application

[Ram9066]

Hi,

I am working on a File upload Scenario using RAP and I could not see Upload button for the Attachment field, instead it is showing as an Input field in object page when clicked on create.  I have followed implementation referring to the below link.

https://help.sap.com/docs/abap-cloud/abap-rap/working-with-large-objects 

Attachment table

define table zlist_att {

  key client : abap.clnt not null;
  key uuid   : char32 not null;
  listno     : abap.char(6) not null;
  attachment : zattachement_inv;
  mimetype   : abap.char(128);
  filename   : abap.char(128);
  comments   : abap.char(200);

}

DTEL - ZATTACHEMENT_INV

Interface view code

define view entity ZI_LIST_ATT
  as select from zlist_att
  association to parent ZI_LIST_TABLE as _list on $projection.listno = _list.Listno
{
  key uuid,
      listno,

      @Semantics.largeObject:{
        contentDispositionPreference: #INLINE,
        fileName: 'Filename',
        acceptableMimeTypes: [ 'text/csv','application/vnd.openxmlformats-officedocument.spreadsheetml.sheet' ],
        mimeType: 'MimeType'
      }
      attachment,
      @Semantics.mimeType: true
      mimetype as MimeType,
      filename as Filename,
      comments,
      
     _list.Lastchangedat as Lastchangedat,
     
      _list

What about the User Interface (@UI) annotation in the CDS View?

Could you check this blog post? Especially "With the latest SAP BTP ABAP 2208 release the RAP framework now supports OData streams.". https://community.sap.com/t5/technology-blogs-by-sap/streams-in-rap-uploading-pdf-excel-and-other-fi...

Found out the issue, Annotation - @Metadata.ignorePropagatedAnnotations: true added to both Interface and projection CDS views causing this issue.

When removed this annotation, the attachment field type changed to EDM.Stream and now field is enabled for file upload.

Closing the Post as answer found.
