Delete DTP OL request for Master data

Question

i have a data source which only allows ful infopackages, once loaded in the PSA  use dtp to load in fullload in the master data attributes .... a request shows up green.
now i need to delete the previous request from PSA9 not a problem)
the 2nd run happens psa is reloaded again dtp loads the request but now i got double records in the attributes.
q1, how do i delete over lapping request using process chains, i can delete them manually but i am lazy i rather have a process chain do it for me at 3:0  am in the morning.
2nd ) does it matter to have 2 or 20 same data requests in the master data texts or attributes, instead of table space does it effect roducitivity?

Answer 1

See , I will give an example to understand how delta dtp works
Case 1 : If you run thru delta dtp
Run IP .....req1.....8 reocrds
Run Delta DTP..... 8 records
Run Delta DTP..... 0 records
Run IP.......REQ2......10records
Run Delta DTP..........10 records
case 2 : If you run Full DTP
Run IP .....req1.....8 reocrds
Run Full DTP....... 8 records
Run IP.......REQ2......10records
Run Full DTP.......... 8+10 records = 18 (since it's full it extarcts all the requests from PSA)
If you load 10 times using delt/full dtp obviously you will have 10 requests in attribues/texts of md
but it will add only new / changed record to the MD tables ..
load 10 times you will see requests - goto SE16 - /BIC/PMDNAME - execute - will show only unique entries
Hope it's clear!
