JAMAシートの『入力データのチェック』機能。
コレを使用してエラーも警告も出なければ、そのデータは承認されるデータと言えるのか？んなワケねぇ。
データの精度とかまぁいろいろとあるとは思いますが、結局のところ『依頼者が欲しい情報が網羅されている』ということが重要です。
『入力データのチェック』は、JAMAシートの入力ルールに則って入力されているかをチェックするだけで、内容については全くのザルです。

試しに、

を、メモ帳（.txt）にでも貼り付けてみてください。"C"or"H"or"D"で始まる9行になるように調整してくださいね。
で、その拡張子を『.csv』に変更してください。
コレでJAMAシートで読み込みできるファイルになります。

で、読み込んで『入力データのチェック』をかけてみると、エラーの一つも出ません。
部品構成としては、1-1-2の三層で、Cは材料が4つ（全て1g）付いています。

製品情報としては品番、部品名称ともに入力があります。
構成部品名称、一切入っていません。JAMAシート上でユニークを取っているのが品番であることがわかります。

材料名称は外部リストからの参照になるので、基本的には自動入力になります。
1つめの材料：『JAMAA4444』の『Iron/Other Iron alloy (Unalloyed, low alloyed)』は、材料コードが『FE@』となり『@』の置換えを要求されます。……消すだけでokです。そんなバカな。
2つめの材料：『ISO1043』の『Plastics PTFE (Filled)』は、材料記号が『PTFE-$』となり『$』の置換えを要求されます。……0でokです。文字さえ入ってれば良いみたい。何の冗談ですか？
3つめと4つめの材料は特にコレといったネタもないのでスルーしますが、エラーや警告の回避自体は簡単なんです。
そういえばPTFEやNBR入ってるのに材質表示も警告出ないな。

あ、材料的には『その材料を構成する主成分が入っていれば警告も出ない』です。つまり、『鉄系』のVDAコードに属する材料であれば、鉄が入ってさえいれば（含有率の問題はありますが）特に問題無いってことです。
※※※2010/03/24:追記※※※
実験してみたら、何でも良いから物質が入っていれば良いみたい。
例えばVDAコードが1.1.1だったら鉄系なワケだけど、アルミ100でも何も言われない。鉄が入っていなくてもお咎めなし。
ザルにも程がある。

ちなみに、『エラー』は消滅させないといけませんが、『警告』は残っていても問題が無い場合があります。これも報告先の要求スタイルによりますが、回避方法はいくらでもあります。


JAMAシートは情報を収集するツールにすぎません。
報告先の要求に合わせた入力内容の把握と、サプライヤーからの成分情報収集方法の構築を推進しましょう。
