Batch Upsert operation using webmethods SFDC adapter 8.2

I am able to insert a single record into Salesforce. However, when I try inserted bulk data using the batch adapter, i get communication error. It’s the same data and same object that worked for a single entity. Any help is much appreciated.

I checked error logs. No information.

Are you using Salesforce Adapter?

What is the IS/JDBC Adapter version and I assume that you are doing batch insertSQL template via JDBC Adapter or SF adapter correct?

HTH,

Yes, I am using Salesforce adapter. The SF adapter version is 8.2
