I gave up of Celigo support. After three weeks waiting, only I got is tests from one of support agent 😭
I foumd the root of problem. The SharePoint export form doesn't provide option to include custom columns. According the SharePoint tutorials, url required a explicit list of columns needed to be returned. It is not NetSuite related, but I would like to know if someone succeeded to exchange data between NetSuite and SharePoint list with Celigo.
