[SalesForce] Retrieve a list of all JobID done in Marketing cloud

I just figured out this seems to be another feature/setting that isn't activated by default and has to be requested as a support case. So even if you see this feature in Email Studio when configuring triggered sends, you need separate activation for use within Journey Builder.

Error Threshold

A configurable limit that stops a send job when a designated number of errors occur.
This option helps prevent a single error from stopping the entire job. Contact your Salesforce Marketing Cloud relationship manager for more information.

(Source: Configure the Send Email Activity)

If the feature is activated there is a global threshold setting defined by support, that can be activated or deactivated in the send email activity via a checkbox. To be more flexible a user defined threshold on a per activity basis would make sense. Therefore I posted this on IdeaExchange. If you like the idea, please vote for it: User defineable Error Threshold in Journey Builder send email activity.

The same way you cause emails to be sent when you create a Case through any other Apex, by setting DMLOptions.

There is documentation on setting DMLOptions, but the highlights of that page are...

Database.DMLOptions dml = new Database.DMLOptions();
// For sending emails to the person designated as the Contact for the case
dml.EmailHeader.triggerAutoResponseEmail = true;
// For sending emails to salesforce users of your org
dml.EmailHeader.triggerUserEmail = true;
// For sending emails to addresses outside of your org
dml.EmailHeader.triggerOtherEmail = true;

If you also have auto-assignment rules for cases that are created, you may need to set another DML option AssignmentRuleHeader.useDefaultRule.

If you're only working with a single case, you can use the setOptions() method of the SObject class to actually set the dml options.

Case c = new Case();
Database.DMLOptions dml = new Database.DMLOptions();
c.setOptions(dml);
insert case;

For lists of SObjects, you'd need to use the database.<dml method>() method instead of just [insert|update] <list of SObject>;. That method only exists for insert and update (not delete, undelete, or upsert)

Database.DMLOptions dml = new Database.DMLOptions();
Database.insert(myCaseList, dml);
