API Error

We tried to send the ‘Job’ UID object as part of each ‘Transaction’ line item, but the API returns an error:

(

            [Name] => ValidationError

            [Message] => BusinessLine_JobHeaderNotAllowed

            [AdditionalDetails] => JobId:(SaleOrderLine)

            [ErrorCode] => 4244

            [Severity] => Error

            [LearnMore] =>

Can you please advise what this is and how we can fix it.
