On the surface this would seem like a fairly straightforward
lookup/data
extraction but in reality it's a bit complex! What makes it complex
are
the cells where there are multiple codes:
-
302+301
302+305
307+312-

CodeListA refers to B$2:B$7
CodeListB refers to B$10:B$15

Create this additional name:

LookupCodes
Refers to:

=TRANSPOSE(INDIRECT(Sheet1!$N$2))

Use the appropriate sheet name.

G2 = some code like 301

Enter this formula in N2. This will return the name of the range that
the
code number in G2 is located in.


=IF(COUNTIF(CodeListA,G2),"CodeListA",IF(COUNTIF(C odeListB,G2),"CodeListB",""))

Enter this array formula** in O2. This will return the count of
records
that meet the criteria.


=IF(N2="","",SUM(--(MMULT(--(ISNUMBER(SEARCH(LookupCodes,E2:E18))),ROW(INDIREC T(N2))^0)0)))

Enter this array formula** in N3. This will extract the dates that
meet
the criteria.


=IF(N2="","",IF(ROWS(N$3:N3)O$2,"",INDEX(D:D,SMAL L(IF(MMULT(--(ISNUMBER(SEARCH(LookupCodes,E$2:E$18))),ROW(INDIR ECT(N$2))^0)0,ROW(E$2:E$18)),ROWS(N$3:N3)))))

Format as Date. Copy down until you get blanks.

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and
the
SHIFT key then hit ENTER.

16 5/6/2010 307
17 1/10/2010 307+312

What i want to do is that when i enter a code (let's say 301) in
the
cell G2, then in cells O3:O15 appear the dates corresponding to the
codes 300,301,302,303,304,305 & 306.
And if i enter 312, then in cells O3:O15 appear the dates
corresponding
to the codes 307,308,309,310,311 & 312 ( taking into account that
"301"
that i entered in cell G2 is a part of "302+301" in cell E6)

I entered 3 formulas that have solved a part of the problem, but
the
last problem is that the date corresponding to "302+301" was not
included coz it's not exactly what I entered in G2.. So could u
please
modify my formulas or create others to solve that problem ??

Here are my formulas

In O1

=LOOKUP(9.99999999999999E+307,CHOOSE({1,2},MATCH(G 2,CodeListA,0),MATCH(G2,CodeListB,0)),CHOOSE({1,2}
,"CodeListA","CodeListB"))

In O2 (ctrl+shift+enter)
{=SUM(IF(ISNUMBER(MATCH(E2:E18,INDIRECT(O1),0)),1) )}

In Range O3:O15 (ctrl+shift+enter)

{=IF(ISNA($O$1),"",IF(ROWS($O$3:O3)<=$O$2,INDEX($D $2:$D$18,SMALL(IF(ISNUMBER(MATCH($E$2:$E$18,INDIRE
CT($O$1),0)),ROW($D$2:$D$18)-ROW($D$2)+1),ROWS($O$3:O3))),""))}

And these are the results

N O
1 Range : CodeListA Where CodeListA is the range B2:B7
2 No. of dates 7 While it has to be 9 !!
3 Dates: 17/3/2010
22/3/2010
14/5/2010
9/11/2010
28/7/2010
2/2/2010
9/2/2010

Thank you
