```The exhibit shows an XML request to create a sales order via the Dynamics 365 Finance data service. The request fails with an error 'Customer account not found'. What is the most likely cause?
⚠ Common exam trap
A common mix-up: candidates confuse a data validation error (like missing customer) with a structural or connectivity error (like malformed XML or wrong URL), but the specific error message directly points to a data mismatch in the request payload.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The CustomerAccount value is incorrect or missing
The error 'Customer account not found' indicates that the value provided in the <CustomerAccount> element of the XML request does not match any existing customer record in Dynamics 365 Finance. The data service validates the customer account against the CustTable before creating the sales order, so an incorrect or missing CustomerAccount value directly triggers this error.
