Hi Sergio,
Don't you have Obsolete change pointers checkbox in DB22 ?
This check box is intended for changed pointers regardless they have been processed or not.
If you look at the program RBDCPCLR (DB22) you will see it executes direct delete on BDCP, BDCPS or BSCP2 and nothing more. So it should be easy to develop a small Z pgm to do it (if your BD22 has not the Obsolete change pointers checkbox of course...).
Cheers
