Enhancement doubts-- Ajay Das or anybody

Hi all,

i was following a discussion about enhancement in which they mentioned about ALE Delta and change pointer tables

message types which i am giving below.

message type RS*nnn, MATMAS

TABLES: TBD62, BD52, BDCP

I think that when we say ALE delta it refers to master data delta...am i right

and what are these CHANGE POINTERS and the tables i mentioned.

Can somebody please explain me their role in delta and how and where are they associated and in which type of delta they play their role for eg: in master data or transaction delta if yes for transaction delta is it for all the application areas.

thanks and regards

Sreedhar
