ABAP Proxy attachment

[DG]

Hi,

I need to send a flat file (a file which has been encrypted) from ERP via PI to a partner.

Is it possible to create an attachment with the flatfile in a proxy interface or even better can I just have the flat file as payload to my proxy.

regards

Daniel

Hi Sarvesh,

It seems to work. It only seems to work with the file as an attachment and not as a main documenent.

Hello,

Yes, it is very well possible. Here is the link for coding proxies:

And here is some example code:

• Attachment objects implement the IF_AI_ATTACHMENT interface. This interface specifies a

• selection of constants, for example IF_AI_ATTACHMENT=>C_MIMETYPE_TEXT_HTML to help specify

• the attachment type. You must specify this constant when you want to create an attachment object.

*

• Methods of Interface IF_AI_ATTACHMENT
