Material Changes not getting transferred to APO

Hi All,

Whenever we use MM02 transaction and make changes to material the changes are getting reflected in APO system

But when use the FM 'MATERIAL_MAINTAIN_DARK' to update the material seems the change pointer is not getting triggered and therefore no update in APO system.

For change pointer MATMAS is checked. Do I also need to to check CIFMAT? Or is there any other issue?

Regards,
