Maximum attached file size in PI

[Former Member]

Hi guys!

I have a question regarding the max size of an attached file in PI. We have an interface proxy to proxy, where we would like to attach a file. What is the recommended maximum size in PI? I have read that SAP recommends 1-5 MB messages to avoid performance issues but I guess it is about the payload not to attachments.

Thanks and regards.

Peter,

     Max SAP PI file size depends on hardware, java heap memory and complexity of mapping (no official file size limit). In your case, it is proxy with attachment and there is no processing of attachment. So mapping complexity is not an issue. I guess you can have 50 MB - 100 MB attachment (or more, depending on java/abap heap memory available when this interface is running).

     To reduce attachment size source system can send proxy with zip attachment.
