Question:

The source Word document contains some equations and it can be rendered successfully if the merge field is disabled. But why is the Word document can not be rendered in Vault when the merge field is enabled?

Answer:

The source Word document has some equations/formulas in the content and the equations/formulas have an unexpected field code in Word which results in a Word corruption during processing.

The problematic code is hidden and users can follow the steps below to delete it:

1. Open the Word locally and press ALT+F9 on the keyboard to enable the field code view
2. Delete the associated field code
3. Save the file and re-upload it for rendering
