Hope someone can solve this problem because it's kept me up for several
nights.
My daughter needs an Excel formula that matches a list of several hundred
dates against a table of sixty dates (which will grow as time passes) and
reports the correct match in each case.
Column A holds dates that documents were received in the office.The dates
are in random order and will be added to continuously.
Column B needs to calculate when each document should have been despatched
from the office. This 'deadline' is the 2nd working day of each month. So
if A7 is 8 June 2006 B7 should be 4 July 2006. If A8 is 3 August B8
should be 4 Sept 20006, etc.
Column C holds the actual date of despatch.
Column D calculates whether the document went on time (e.g the date in
column B is less than the date in column C) or was late. Everything
depends on the date in Column B being correct in each case.
I created a table listing the '2nd working day' for each month. What I
can't work out is how to match all the receipt date in column A (e.g. 8
June 2006) against this table and put the correct date in column B for
each document.
The 'month' formula will not work because the deadline for documents
arriving on 1st or 2nd working day of any month will be that same month.
Only if the document arrives from 3rd working day onward does the
deadline become the 2nd working day of the following month.
I tried using a 'Look Up' table. This only works if the receipt date is an
exact match for one of the dates in the table. Any other date gets
'rounded down' (e.g. documents received on 8 June were 'matched' to 2 June
instead of 4 July.
I tried a nested 'IF' approach. (e.g. IF the date in A3 is higher than the
first date in the month table but lower than the second B3 shows the
second date, IF A3 is higher than the second but lower than the third
date, etc.) but cannot work out how to do this for every date in column A
without changing the formula for every single entry in column A.
If anyone has a solution I would be delighted to hear it. If your proposal
involves Visual Basic please put it in full because I have never used VBA
and won't understand general references to "just add the following. . . ."
Appreciate your help in this
Kind regards
