Excise year for TDS certificate

Hello,

When I try to post vendor invoice with withholding tax I am getting the following error message ..

"Could not determine the year for TDS certificate number range"

Message no. 8I017

Diagnosis: The excise year could not be determined for generating the numbers for TDS Certificates.

Procedure: Maintain the start month for the excise year correctly .

I have already maintained the numebr ranges for challan and WHT certificates.

Can someone please tell me where can I maintain the excise year and resolve this issue

Thank you

Anil
