Batchsync Class Statuses are not updating when push from integrated system to SalesForce error message received 'You are receiving this email because you are a member of the Public Group 311 Lucity Failure Notifications.\n\r Unable to update the cases given below due to errors. Please Find the Error Details Below\n';   The only thing that I can think that may be going on in the code is that the batch id identifier  changes when push back to Salesforce, meaning no match is found in Salesforce to update the statues. Another developer wrote the below code, and I am still new to apex code.  So I am not able to interpret everything that is going on in the code. Does anyone have an idea of what could be stopping the update of statues between the integrated app (Lucity) and SalesForce.. Code is attached. Thanking you in advance for any assistance that you may be able to give me.  Frances
