Changing Key Field to Data Field in DSO

[kumbasarm]

Hi experts,

in BW 7.5 PS-Reporting we have different DSOs for which several key fields are defined. Because of these multiple key fields, some key figures exist duplicates.Now I would like to reduce the key fields and define the unnecessary fields as data fields. I know that I have to delete all data, but how and where can I determine which correct key fields I need?

Thanks for your guidance.

Regards

MK
