CST No. Field Missing in Company Details Form!

Dear All,

While I was trying to add CST No. in the "General Data" tab under "Accounting" tab in Company Details Form (India Localization), I found that there is no such field available for input. I am using SAP B1 9.0 PL05 version. I have attached the screen shot for reference.

Can anyone please help me out as to whether this is a kind of bug in the system or am I missing something?

Thanks in advance for your help!!!

Regards,

Khushbu
