Hi,

Can you provide a screenshot a of the logon & security tab please?

The user mentioned there must be a technical user on the SAP PO side.

Make sure role SAP_XI_APPL_SERV_USER is assigned.

Kind regards,

Dimitri

Is your SAP_PROXY_ESR is working?Please check SPORXY.

Can you try to delete and recreate the destination pointing to AEX

Thanks

I see an N in the proxy user field in your screenshot. Please remove it.

On your SAP PO system, I assume you have a Business System representing your ECC system.

Also, do you have an active sender SOAP adapter configured?

ok problem solved I think caused by "xiadapter.version.minor" parameter  set value 0 and CPA cache refresh.

thank you for all your support...
