I am getting the following error on the Account record when trying to push to NetSuite:
'EXCEEDED_MAX_FIELD_LENGTH: The field comments contained more than
the maximum number ( 999 ) of characters allowed.'
This error is being generated from Salesforce because the field value coming from NetSuite exceeds the allowed characters for the mapped field. In this case, the Comment field within NetSuite is mapped to the Description field in Salesforce. The description field is hidden in the Salesforce form. If you modify the form and add the Description field, you would see that it contains a value that contains more than the allowed characters. The value must be changed to something that contains less than 999 characters.
