BIMLとSSISは独自のデータ型を使用しているためです。正しいデータ型のために、このリンクを参照してください:あなたはスニペットにあなたのコードでこれを入れて、それを呼び出すことができ
https://www.cathrinewilhelmsen.net/2014/05/27/sql-server-ssis-and-biml-data-types/
。また、自動的にSQL Selectを記述できるように、ソースをExternalTableInputから直接入力に変更する必要があります。これは古いコードです - DLL Libarayに入れるのがはるかに簡単です。
は何私が行っていることは、このようなものです:あなたが見ることができるように

問題はバイパスできるValidateExternalMetadataをfalseに設定してsedしてください - とにかくこのエラーの理由を知っておくといいでしょう... – Tyron78
ソースと宛先はどちらもSQL Serverですか?また、すべてのパッケージが 'dbo.DWH_SalesHeader'をソースとして使用する必要がありますか? – billinkc
いいえ、ソースも変わります - コードを変更しました – Tyron78
