If it is an incremental file, can we rely on the maximum timestamp value being the last line of the input?
Does every line in you input always contain IN PROGRESS in the next to the last field? Or, is the real problem to find the last line in the input file that contains IN PROGRESS and change that text on that line to COMPLETED?
If you're really trying to find a maximum value in a field when the input is not in increasing or decreasing mathematical order, neither sed nor vi have that ability (unless you want to use the vi command that replaces text with the output of a shell command to sort the file).

DLASRT sorts numbers in increasing or decreasing order.
Function/Subroutine Documentation
subroutine dlasrt (characterID, integerN, double precision, dimension( * )D, integerINFO)
DLASRT sorts numbers in increasing or decreasing order.
Purpose:
Sort the numbers in D in increasing order (if ID = 'I') or
in decreasing order (if ID = 'D' ).
Use Quick Sort, reverting to Insertion sort on arrays of
size <= 20. Dimension of STACK limits N to about 2**32.
Parameters:
ID
ID is CHARACTER*1
= 'I': sort D in increasing order;
= 'D': sort D in decreasing order.
N
N is INTEGER
The length of the array D.
D
D is DOUBLE PRECISION array, dimension (N)
On entry, the array to be sorted.
On exit, D has been sorted into increasing order
(D(1) <= ... <= D(N) ) or into decreasing order
(D(1) >= ... >= D(N) ), depending on ID.
INFO
INFO is INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
