This error can occur when attempting to accept contracts:
To bypass contract demo validations, click the “Ignore Demo Validation” checkbox.
Ignoring demo validation means that if a contract demo is not on the Product/Estimate demo list, you will not receive the error message stating that “Contract demos do not match Product/Estimate demos” and you will not have to add/remove any demos to allow the upload.
Click the Demos button to view the Contract Demos and Estimate/Product Demos:
Note: Only the Estimate/Product Demos will be uploaded to the Network buy when the contact is accepted.
