TDS Standard Invoice Not generating

Hi,

We have two operating Units A and B. We created supplier  TDS Tax Authority and Site Chennai for both the operating units A and B.

TDS Standard invoice and Credit Memo is generating for OU A. No issue in OU A.

Credit Memo only generating for OU B. TDS Invoice stuck in Payable open Interface with error message Invalid Supplier Site.

We attached same supplier site Chennai at two OUs of First Party Registrations setup.

Can't we use same TDS supplier site for two OU's?

Thanks,

Hari.
