How can we Roll off data from data targets and to get updated data only.Let me know clear functionality that BW provides.
Thanks in advance.....
Welcome to SDN.
Rolling off data functionality is not there in BW.If you want to know the functionality then its nothing but deleting data in a rolling manner.Rather deleting all the data at one shot, we can roll off the history data at a different intervals.
Its again depends on your data target and loading process.
You can do this by placing ABAP code in infopackage level.
Please let me know if you need any further clarifications.
