Release 1634 is another modification of PPP520, but -not- for PostDocs
this time.  Instead it addresses an occasional aberration in the way
benefits are charged.  Here are some remarks from the release letter:

     ...occasionally, when vacation usage (DOS "VAC") is reported, an
     inordinately high Health benefit is assigned to the PPP5302 VAC
     distribution entry.  This results in an excess amount being charged
     to the Leave Reserve Account and credited back to the departmental FAU.

     ...when a normal pay (e.g., "REG") entry Gross amount was greater
     than the total current Monthly Gross, then, if a VAC entry is subsequently
     processed for this individual, the VAC entry was improperly assigned
     the full Monthly Health benefit charge (rather than a portion of the
     Monthly Benefit based on the relative amount of the VAC Gross and
     the total current Monthly Gross).

     The probability of this error occurring was exacerbated with the
     implementation of the START program.  It is most likely to occur when
     an employee receives only one positive amount pay distribution in
     the month along with one or more negative pay distributions followed
     by VAC usage entries.

     Program PPP520 has been modified so that the processing exceptions
     for VAC entries will test the VAC separately for a Proration Percent
     in excess of 100% and only then, limit the benefit assignment to the
     full Monthly Benefit amount.

It amounts to only a few lines of code in PPP520 and there are
no table updates.  May we have your ok to install?
