Hi,

pointers - as the name says - point. They point to change documents. So you've got to create change documents first:

1) Define Chenge Document Object (tcode SCDO)

2) Generate function

3) Check that all dataelements you want to trace are checked as relevant for cahnge documents

4) build in function wherever you change DB

6) define an ALE Message type (WE-81 you don't have to use ALE)

5) acticate change pointer creation (BD50)

6) define tables/fields for change pointers (BD52)

7) filter CP unwanted CP (at least duplicates for the same object) with BADI BDCP_BEFORE_WRITE

If 3) is not fullfiled for some tables or you want to skip some points you may use FM CHANGE_POINTERS_CREATE_DIRECT.

Have fun,

Hi,

call FM CHANGE_POINTES_READ fo find pointers (They may be either in BDCP2 or BDCP/BDCPS).

You may also check creation of pointers in DEBUG at the and of FM CHANGEDOCUMENTS_CLOSE (activate DEGUG for update).

Kind regards,

1) Creation fith CHANGE_POINTERS_CREATE_DIRECT is inly neccessary when you do NOT write change documents (or the flag at certain dataelements are missing)

2) Filtering: BADI name is BDCP_BEFORE_WRITE. To look at definition use tcode SE18 for implementation use SE19. Note: activate implementation. For debug activate update debugging.
