HI tim,

Thanks for that reply. Then again what I needed is maybe a VBS code so that
I wont need to copy and past as values the whole data everytime. Nontheless I
tried the formula you had given but it seems there was an error in column f2
which I cant figure out. Thanks anyways! :)

Assuming your data below is in cols A-E and the first row of data is
row 2

Add 2 helper columns in F and G as follows:
in F2 put: =+B2&"_"&REPT("0",2-LEN(MONTH(C2)))&MONTH(C2)&REPT("0",3-LEN
(DAY(C2)))&DAY(C2)&YEAR(C2)&"_"
In G2 put: =COUNTIF($F$2:F2,F2)

The sequence # will be in col. H as follows:
in H2 put: =+F2&REPT("0",4-LEN(G2))&G2

just copy the formulas down.

The spreadsheet will start to slow down if it gets large so you may
want to copy / paste values over these formulas every so often.

Hi all,

I have a project to make in my office. I need to automatically create a
sequential reference number for a set of data. Please see below table.

Cust No. TA No SI date Amount Rate
008-018970 01 0500247 22-Sep-08 12,000,000.00 0.25%
008-018970 01 0500247 22-Sep-08 11,000,000.00 0.25%
050-101393 01 0500324 20-Oct-08 5,000,000.00 0.25%

I have 4 columns (column a-e). What I need to do is to generate a unique
reference code for each item in the row in this format (TA No._MMDDDYY_####)
#-representing the sequential number. Is this doable? thanks!
