FM or BAPI for VF03, FB03 attachment list download

[ando1692]

Hello!

Which BAPIs or FM shall I use to download GOS attachments (VF03 transaction with billing document number, attachment list)? The attachments are downloaded via http (files are in a web server). Same for FB03 transaction (with supplier invoices).

I mean the “export” functionality that it’s within the attachment list tab. When doing manually (if I double click on attachment itself) my browser is opened and pdf file is shown. I have inspected this and an http request is made to some server, which returns the pdf itself. I have looked some FM such as BDS_GOS_CONNECTIONS_GET (which returns the metadata of the attachments, but cannot download the attachment with that one) and BDS_BUSINESSDOCUMENT_GET_TAB which does not help.

Thanks a lot

It has been asked so many times, and there are many possible solutions. As you are asking about BAPI, there's only one which is BAPI_REL_GETRELATIONS to read the list of attachments. For reading the IDs of attachments, and for reading each attachment you may search the Web: "GOS" "attachment" "github" site:sap.com (one ABAP GitHub project)

Note that GOS attachments may not always be stored in BDS.

Hello Sandra,

After investigating and following your advice I've found the github repo that you were talking (I think it's https://github.com/keremkoseoglu/ABAP-Library/blob/master/document/zcl_bc_gos_toolkit.abap). This is more than enough for investigation and start testing it. Really appreciate your help, gracias 😊
