Error message - Contract not active / Pending creation.
This error occurs when the contract linked to the customer is not currently active and cannot be updated through a file upload.
Check the customer's status on the Contracts tab. If the contract has been cancelled, you can view the cancellation date and reason on the Contract Updates tab.
If the contract shows as Pending, it is still being set up and is not yet available for updates. Wait until the contract becomes active before attempting the upload again.
Once the contract is active, re-upload the file to apply the changes.
