Mass change in IW37N

Hi Experts,

I understand activating LOG_EAM_CI_5 enables the "Mass change" functionality for Order Operations. When we tried doing this, it got enabled for IW37 and IW38 and not for IW37N. Although the SAP note has a reference to IW37 only, does the standard enables only for IW37 and IW38 and not for IW37N?  It would be beneficial if it gets activated for IW37N also. Do I have to get any other business function activated to enable this? Are we missing something?

Thanks in advance.
