The function of life science fields in production parameter setup

Dear All,

I have tried to download AX 4.0 helps from MSDN or microsoft download center website but it said there is no available file to know the fields named life science on tab general of production parameter set up in production parameter set up window. Could you let me know the useful and what type of manfuacturing companies will need the fields ? I can’t find the definitions of fields in life science section . The fields are mandatory date, block removal of approval and block editing.
Any helps from you about the fields explanation I appreciate so much.tks
