The DFF Additional Absence Detail Information Doesn't Work For China Legislation

Hello Gurus,

I encountered the following problems：

The DFF  can not display on the Absence Attendance Type Form,but The  Add'l Absence Type Details DFF does work.

What is the difference between  Additional Absence Detail Information and Add'l Absence Type Details?

I need Additional Absence Detail Information to work, How can I do ?

Any suggestions

Thanks a lot
