• ADvendio now displays errors in the UI and sends you email when transferring AdServer IDs, Keys, Values.
• Administrators only: More specific information to the error messages can be found in Environment → Jobs → Bulk Data Load Jobs. Then select the Job by clicking on the id and scroll to the batches list and view the results

• If you are getting an "Import Inventory raise Error when AdUnit Name is longer then 80 digits" Please update to the newest ADvendio version. The name will then get automatically truncated 80 characters and imported fully into the field ADvendio_AdServer_Name_c.
• If you keep getting an "Transfer is still in progress. Please try later again." error, but are sure that there is no more transfer in progress, please manually edit your AdServer Login and set the Checkbox "Transfer in Progress" to false. Attention: Only do this, if you are sure no transfer is running (depending on the size of your inventory and targeting criteria, the transfer can take a long time). Otherwise the import might be interrupted and has to be started again. 

One thing that could happen after the process is successfully completed, you could see that on the results page after trying to transfer Adserver Login Data that "0 Ad Server Ids to ADvendio transferred successfully". this is because for the profile of the user trying to transfer the data  you would need to have the AppNexus record type for the Adserver ID's. To make sure this is done, go to setup, profiles, (your profile), Object Settings, AdServer ID's and assign the Adserver you're trying to transfer record type to the profile and test again
