Can this SAP-Note be imported?

Hi Gurus,

I'm face a problem with IDoc_AAE for sending IDoc Extension.

From all symptom I'm sure, that this is the error descripted in the SAP-Note 180511.

But my basis team told me they cannot import it because the current PI is already PI7.31 SP 7 Patch 4.

Here is the screenshot:

But, after longtime reserching, I cannot find other reasons.

Please help me to check whether this note is really not importable?

Thank you for your prompt reply!

Regards

Rene
