TDS for payee having different branches but single PAN

Dear Income Tax experts,

I am S.Ravichandran who is working as commercial manager in a private concern. Regarding deducting

TDS, if a deductee has different locational branches but has only one centralised PAN number in his corporte office,

what should the TDS deductor do while disbursing the payment. Should all  the branches payments aggregated or not ?

Pl. clarify.

Thanks in advance and rgs.

S.Ravichandran
