Hi Diana Bookwerx ,

Thanks for reaching out. Did you ever find an answer for this issue?

Based on the information provided and the specific error message you mentioned, it appears this issue might be related to the setup of sales taxes within the application. An article from our Knowledgebase addresses a similar error when creating a purchase invoice, suggesting that improperly set up tax codes could be the cause. The resolution involves verifying that the tax codes are correctly set up. If you're not using sales taxes, another recommendation is to go to the Taxes tab in the Vendor record and switch the tax code to "No Tax" for all vendors before trying to save the purchase invoice again.

For detailed guidance, including how to manually update sales tax codes, please refer to our Knowledgebase article here: How to address "Unhandled Exception" errors related to purchase invoices and sales taxes.

If these steps do not resolve the issue, or if you need further assistance, please don't hesitate to get back in touch. 

Warm Regards,

Erzsi

Hello, I haven't found a resolution yet. Thank you for the suggestion.  My sales taxes are set up properly.  The error comes randomly, sometimes when I've posted a tax, sometimes when I haven't.  Sometimes shortly after I've opened a company, sometimes after several hours of work.  There's no consistency other than the frustration I feel.
