Change Pointer for EDP13 and EDP21

Hi Guys,

I got one requirement where I need to fetch the data for Create or Change in Partner Profile(WE20)  and pass it to one non SAP system at runtime. Table EDP13 and EDP21 is updated with the data when we create or change WE20.

I am trying to do it using change pointer, but for these two table I am not sure is it possible to have change pointer? None of the fields in the table EDP13 and EDP21 has the check box 'Change Document'  enabled.

Can you suggest how we can do it.

Thanks
