Hello Expert,

I tried to use the API com.sap.odp.api.common.types.AttachmentIfc for  uploading the attachment to any document Type.

please correct me if I could use this.

The method under this API setFileData(attachmentName,sfile,iBean,session) .

When I am using the above method I am getting exception like.

I think I am not able to call the setFileData() corectly.

Could some one please help me.
