/ACTIVITY=code | CONSTANT=integer

    Specifies a license unit code that corresponds to a License Unit
    Requirement Table (LURT) or to a constant value. If your PAK
    supplies an activity code, you must enter the code exactly as
    it appears. The current codes are A, B, C, D, E, F, G, H, and I.
    If your PAK specifies the keyword CONSTANT, then you must also
    specify the integer value. This denotes a constant requirement
    for all System Marketing Models (SMMs) equal to the value given.
    If your PAK specifies the decimal value 0, then the license has
    no requirement for that license type. PAK issuers determine the
    value for this element.
