Picking VN address email instead of ordering address OA

Hi All,

We have scenario where user created PO with vendor for example A00001 with Partner function VN which is main vendor and has partner order address OA ex A000011 and PI A00022.

Now when user creating a PO email is triggering to main vendor not to the OA address. I tried to replicate to replicate the scenario in quality system but it working fine there and email is triggering to OA address.

Request to you  all to suggest what are the other things I need check.

I have checked Partner functions in customization condition records.

Thanks&Regards,

Chand.
