Activate Change Pointers for Purchase Orders

Question

I thought that change pointers would be active by default for purchase orders, but when I change a purchase order field that should be change pointer enabled, nothing is written in table BDCP.
Here's what I have done:
1) Used transaction SCDO to look at the change Documents.
2) Identified object EINKBELEG (Purchasing Document) as the likely object.
3) Verified that table EKKO is one of the tables in the object.
4) Verified that the data element of the field that I am changing in the PO - ZBD2T - is change pointer enabled (it is).
I cannot get any entry created in BDCP with these settings; change pointers are working for other documents.
I also put a breakpoint on the sebugger for the function module EINKBELEG_WRITE_DOCUMENT in the update task, and I cannot see it being triggered, so I am wondering if I am doing the correct thing here.
Can somebody please tell me what I am doing wrong?
BR,
Tony.

Hi Guys,
This issue was solved by implementing the BTE 4005 (OPEN_FI_PERFORM_00004005_E). This particular event is triggered in the update task for saving changes to business object. So In my function module (corresponding to BTE), I have explicitly called the method to write an entry in COM_SE_CPOINTER, because we just need the reference of business object for which classification data is changed.
Please refer the below code for more clarity.
BTE position: -
method called in FM to write change pointer.
Thanks anyways, for all the responses.
Cheers,
Shreya
