If a column name exceeds 50 characters when you write data to Salesforce Analytics, the task fails with the following error:
[ERROR]Error occured while writing data to the target native system : [java.lang.IllegalArgumentException: field name cannot be greater than 50 characters]
If you include a partitioning-enabled source and Salesforce Analytics as a target in a mapping, the mapping fails.
The Monitor may show a job as completed successfully even if the job fails or ends with a warning.
Workaround: You must download and check the session log to know the exact status of the job.
If a column name in a source contains a hyphen (-) or a double underscore (__) character, the task fails with an error.
