What are the causes of an unexpected error when trying to create a new transaction, such as a sales order or invoice?

AI generated answer (using internal Slack threads):

The causes of an unexpected error when trying to create a new transaction, such as a sales order or invoice, can be due to several reasons: 1. Custom Form Issues: If you are using a custom form to create the transaction, there might be some issues with the form itself. This could be due to incorrect field mappings, missing mandatory fields, or other form-specific settings. In such cases, creating a new custom form might resolve the issue. 2. Inactive or Missing Tax Codes/Accounts: If there are any missing tax codes or if any item/tax code accounts are inactive in the backend, it could lead to an unexpected error. Ensure that all tax codes and accounts associated with the transaction are active and correctly set up. 3. Incorrect Field References: If you have added a field that references another field which does not exist in the transaction, it could lead to an error. For example, adding a sales order field that pulls from the shipdate by default might cause an error if the transaction does not have a ship date field. 4. Scripts or Workflows: Sometimes, scripts or workflows deployed on the record could cause unexpected errors. These could be due to bugs in the script or workflow, or due to conflicts with other scripts or workflows. 5. Web Services Issues: If you are creating transactions using web services, there might be issues with the web service itself. This could be due to incorrect API calls, missing or incorrect data in the API request, or other web service-specific issues. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
