No macro's! Just sort your input on InvoiceNo and insert subtotals on every
change of InvoiceNo. You can find the function under Data/Subtotals

But my problem is slightly different.
Let me explain it.
See there is a Macro already written which is connecting to the
Database to run a function returning a Recordset. Using this
RecordSet the excel  is populated with columns  as Headings and some
columns has some formulas written.
Now after all this is done I want to call a function which will add
a column called total and display the records as shown in my earlier
post. I will have to select the columns name , range and create a
formula for TotAmount.

Whilst a macro  could certainly be written to do this, there are 3 other
techniques, none of them needing VBA, which you ought to consider first,
particularly since these will do what the VBA you seek will not, which
is react to additional data  input.

The first and potentially most flexible and quickest is to create a
pivot table and there are many web guides to doing this if you've never
done it.

The second and third are to use array formulae or D-functions; if you
have a lot of data I'd recommend the latter. I have articles on how to
use these here:

http://www.grbps.com/Excel5.pdf (array formulae)
http://www.grbps.com/Excel3.pdf (D-functions)

But my problem is slightly different.

a column called total and display the records as shown in my earlier

formula for TotAmount.

For Example : Present Macro has some code which looks like the
following.

oRPT = WorkSheet

ThisName = RNAMECumRRBilled
oRPT.Range(oRPT.Cells(Range(ThisName).Row, Range
(ThisName).Column), oRPT.Cells(Range(ThisName).Row + RowsIn, Range
(ThisName).Column)).Select

Selection.FillDown

I don't understand what formula is it creating for this column and
how is it creating.

Yes, I am getting you, but the pivot table, array formulae, D-function
and subtotal methods will all give you the totals you seem to need. Have
you tried them?

Bearing in mind you seem to be getting new data  straight from a
recordset, I'd use either subtotals or the pivot table, since either can
be set up in just a few seconds.

That is the big problem as I said am completely new to writing  a VBA
macro I was hoping for a code snippet which wich would give me some
tips on how can I do it with the existing macro. I will paste a code
snippet which is there pls advice me how to proceed. It does not
have a pivot table?

The following function (PrepareTheReport) is called from the mail
function. I need to add an extra column at the last row for evry
similar BillingDocumentNbr. There are lots of repeating
BillingDocumentNbr's with corresponding value for CumRRBilled. I
need to total up CumRRBilled for all similar BillingDocumentNbr's.

Please do me a favour and help me.

I have directed you to the
solutions to your problems; you really don't need VBA to do this.
Particularly since - as you say - you are not experienced in VBA, an
inflexible VBA solution won't be the best way to help you.

I've given you links to investigate Dfunction and array formulae
solutions. Here is an introduction to pivot tables in Excel - THIS IS AN
EASY WAY TO ACHIEVE YOUR REQUIREMENT; most of us in here believe you
should only use VBA if you can't achieve your aims without it and this
is not such a case.
