No event sent by the event sender

Hi all,

I have a problem with B1iSN 8.8.

I have configured the standard flow Purchasing - Sales from local stock.

The problem is when I create a PO in the company "Subsidiary", B1iSN detects nothing.

I have configured the event sender correctly (on my point of view) and started the service. I have configured the Biz package as indicated in the documentation. So I don't understand what is the problem.

Moreover, I don't have any log.

I have just a technical log that appears at startup of B1iSN saying

com.sap.b1i.xcellerator.XcelleratorException: XCE001 Nested exception: com.sap.b1i.bizprocessor.BizProcException: BPE001 Nested exception: com.sap.b1i.xcellerator.XcelleratorException: XCE001 Nested exception: com.sap.b1i.xcellerator.XcelleratorException: XCE001 Nested exception: java.lang.Exception: com.sap.b1i.xcellerator.XcelleratorException: XCE001 Nested exception: com.sap.b1i.adapter.jdbc.JdbcAdapter$LoadJdbcDriverFailureException: Could not find the driver 'DRIVER UNKNOWN'

For the IPO step

/B1iSNTools/com.sap.b1i.datasync.b1isntools/ipo/dev.ipo/EventGeneratorJob

But I am not sure the error is linked because I have tested the connexion to the SBO companies and the connexion to the event sender and everything is OK.

If you have an idea, you're welcome!!!

Thanks
