When we are adding and removing the attachments from opportunity the change history is not getting updated.
But in table CDHDR changes are getting reflected but not on UI change history Assignment block.
Maybe this helps.
I have used Class 'CL_CRM_COMPONENT_CHANGE_DOCS' and method 'READ_CHANGE_DOCS'.
Its not returning values of Object class 'ATTACHMENT'.
My only suggestio is to debug "break-point".
