Hello,
I prepared query for vendor inforecord. Is there any table where you can see when and with whom was inforecord changed (last change). There is a table where you can see when inforecord was created (EINA-ERNAM / EINA-ERDAT => General data and EINE-ERNAM / EINE-ERDAT => Purchasing Organization).
I know there is a option to see history of changes of inforecord (Tr. ME14).
