BDCP_BEFORE_WRITE Change Pointers

Dear All,  

Currently in our system ,

change pointers are configured in such a way that when ever their is change  / removing / adding a new manager BDCP2 table is getting update with change pointer. Further,  that entry is getting picked by program RBDMIDOC program for IDOC generation.

New Requirement :

Along with Manger they need pick the people sharing the same manager to be updated in change pointers.

For this :

BADI : BDCP_BEFORE_WRITE is proposed for this requirement.  For this we are planning to add the people below the manager to the changing parameter : CHANGE_POINTERS. Can we do this or not ?

if not so kindly please suggest me another option.

Thanks

Arpita.
