if you only want the ones that are in Process chains that are actually running: you can go through ST13 'BW-TOOLS'. choose Process Chain Analysis, execute. choose process types. take a big time frame (eg last 4 years). as process type take DTP_LOAD and LOADING.
this will give you a list of all dtp's and IP that have been executed within process chains.
