「何か月前に利用したか」と「再度の利用の可能性」という言葉から、消費動向分析のようなものだと推測します。 が、何のデータから、何が知りたいかをもう少し具体的に書くともう少しアドバイスが集まるかもしれません。 再度の利用可能性という表現だけでも、いろいろな可能性が考えられます。 ・将来、再度利用する可能性がどれくらいなのか（特定の期間内での予測値を月ごとに0-100%で得たい）、 ・次はいつ頃利用するのか（利用する月自体を予測したい） ・特定のユーザに対しての行動の分析なのか、全体的な傾向の分析なのか   （具体的な分析手法については私はわからないのでアドバイスできません）   ...

Go back to Oracle Virtual Box and add the folder again, then restart your virtual machine and browser and test it again.  ... View more

Libname statements are not issued automatically unless issued from an autoexec used when starting your SAS session. Not clear what the issue you are facing, perhaps if you have log the share? ... View more

Hi Kokodenden52,   While I never encountered this error before, I can try to help. Would you have the actual log of the run?   Also, seeing the metadata definition for this library may be useful.   I see you use "METAOUT=DATA", are you sure this is what you wanted?
