Hi All,
I have a requirement from the client to remove the data for a field A in a BW DSO which contains data for last 7 years.
This field A is key field in the DSO and the data for this field is considered to be sensitive, due to which client wants this data to be removed from BW completely and populate a new field B in the place of A in that DSO.
This data for the last 7 years, is not available in the source system for me to reload , if I delete from DSO.
Similarly, I have to delete couple of fields from master data attributes of 3 to 4 objects and their data completely out of BW.
The field A mentioned above is being looked up in the Transformations/transfer rules to derive certain other attributes in some of the other objects and similarly field A is used for checking integrity in generating data for some custon built ABAP reports in BW.
Given this scenario, please suggest me the best methods to solve this request.
Thanks
DM
