Exit/Enhancement for External Send

Question

Hi all,
I have a requirement that needs to retrieve the correct email recipient of vendor(this is for PO). A custom output type for External Send is maintained in NACE. The vendor has two email address maintained (one with a note that it is for PO), I can check which email address is correct through tables ADR6 and ADRT. Buts there any exit/enhancement where I can add the logic for this?
Thanks,
Eo

Check enhancement 'LMEDR001' this is the customer exit that would be used for enhancement of the print program check the changing parameter CX_DOC which is of the type MEEIN_PURCHASE_DOC_PRINT which has structure 'MSGPA' which should have address numbers information.
How does that help though?  There's no access to the e-mail address - what he's trying to do is set the correct address when multiple ones exist on the vendor.
As I remember, with the PO external send processing, you could only use the default address on the vendor (because of a hard-coded READ in the code), so we use the default e-mail address for PO sends and for other objects such as payment advices (where you can actually pick the e-mail address), we tag the notes with an identifier.  I have not revisited this code in ECC 6.0 though.
You can see where the e-mail address is set in function CONVERT_COMM_TYPE_DATA; it uses the old macro calls to set the e-mail recipient which is derived from a simple ADDR_GET call (using the address number).  There aren't any exits here but you could use an implicit enhancement to change the values.
