* Match and merge performance and features - with more data volume the performance level goes severely down. Also the transformations cannot be mass downloaded or mass uploaded, as this leads to painfully pasting them one by one. No de-merge feature is also a point which will help going back to previous state after a wrong merge is done. * Change tracking - This is one tool which lacks and ease of use details which SAP ECC users are really used to.It is not user friendly,performance really goes down sharply as data growth happens. I would like to see improvement in the match and merge performance and I would also appreciate it if SAP can suggest certain ready to use usage and maintenance guides on change tracking. Currently there's only SAP notes and other documents are available but they are suggestive and leave plenty to be said.
