AI_SC_REFRESH_READ_ONLY_DATA error: Error during call of SAP back end system (see long text)

Dear experts,

We get below error when run job AI_SC_REFRESH_READ_ONLY_DATA

Error during call of SAP back end system (see long text)

In SOLMAN_SETUP>System Preparation>Specify Connection Data, password and all configurations are fine

And SAP-OSS and SAP-OSS-LIST-O01 connection and authorization test are both fine

So, why I got error calling SAP back-end system: Error when opening an RFC connection (LB: Hostname or service of the message server unknown via RFC destination in AI_SC_REFRESH_READ_ONLY_DATA SM37??

Regards,

Fadzly Iqbal
