Hi GT SAP,
The Vendor mail ID is picked up from vendor master- address tab itself.
In Other communication, you just have the option to mention whether OR NOT to use a particular mail ID.
Sometimes, it may so happen that the user has given a strict instruction not to use a particular mail ID, then you can mark that for "DO NOT USE"
But the Vendor E-mail ID is same..
Hope this helps.
Regards,
Kavita
