Steps
Note that the Format Version record is added automatically to every file returned by DownloadCampaignsByAccountIds or DownloadCampaignsByCampaignIds
Confirm the file's Format Version Name field equals 6.0, currently the only supported bulk format version
Remember the bulk format version is independent of the Bing Ads/Microsoft Advertising API version being called
When constructing an upload file by hand, include a Format Version 6.0 record and ensure it precedes all other record types in the file
Order parent-entity records (e.g. campaign) before dependent child records (e.g. ad group) in the same upload file
Known gotchas
The Format Version record itself is read-only for Add/Update/Delete — you can't change what version a downloaded file reports, only what version you declare when uploading
Omitting or misplacing the Format Version record in a hand-built upload file breaks parsing since it must come first
