SLP Integration with SAP EHP4 through webservices

[javiergc]

Hello,

We are having some issues trying to implement Ariba SLP with our SAP System. Ariba SLP demands a SAP ECC EHP6 as minimum and currently we have EHP4 and the upgrade is not possible.

We thought about possible alternatives to communicate ECC and Ariba through PO and some Ariba webservice, should this one work?.

Im trying a communication test from SOAP UI and im receiving this error message, which i dont know what it means:

Message: An exception occured when validating the message: System is unable to process your request at this time.. Error Reference Number 2669010671662

Any help possible will be more than welcome,

Thank you in advance,

Best regards
