How to change email/fax number retrieval logic for output...

Question

Hi,
In my requirement, for sending the output by fax / email, for e.g. take certificate of analysis, the customer master data is checked and the data mentioned there is used to send the output. In addition, in customer master transaction XD01/XD02 I see an additional tab called contact person which has information of each contact person along with their department numbers and fax num and email ids.
In ADR3 I noticed that these are stored.
In short
In XD03,  under address tab a fax num maintained which I do not want to use. Rather,
Under contact person tab , the entry which has dept number as say A100, the associated fax num is the one to which I want the COA to be sent.
Where exactly is the code that reads these entries and determines the fax number and email ids to which the output needs to be sent ? May be there I need to change the logic to include a check such that entries that have dept as A100 will be checked and those fax and email ids will be selected and set.
Or if there is any other way this can be achieved, pl advise.
thnks

Senthil,
The COA trigerring works fine. The delivery for  which PGI will be done and then COA will be sent that has the output configured such that Fax will be sent. In SOST I can see the entry which shows the fax num as say 787878.
But this was the number found in the ADDRESS tab in XD03 for that ship to partner. I do not want that fax num to be used. I want the fax number that I enter in an additional tab and which is stored in KNVK and ADR3 tables.
So once SAP determines it has to fax the COA , SAP shoud be reading the ship to pary fax num, right ? Where is that code in standard SAP ? Bcos I need to change the logic to read somwhere else !! Hope you are able to follow me now ?
