I created one WHT Code (I7) and WHT type (I1) for Section 195 (foreign parties). I created these WHT type and WHT code like indian WHT type and codes. I went through SDN posts and did following things:
I maintained entries in SM30 in J_1IEWTECESS as
Country: IN, WHT Type: I7, WHT code: I1, Sec Cess: X.
and i also maintained in SM30 in J_1IEWT_ECESS1 as
Co.Code: 1000, WHT Type: I7, WHT code: I1, Rec: CO, Ecess Rate: 3%
Also i ticked in the check box for company code 1000 in SPRO --> Financial Accounting Global Settings (New) --> Withholding Tax --> Extended Withholding Tax --> Calculation --> India --> Surcharges --> Maintain Surcharge Calculation Methods.
Then i posted one Vendor Entry in FB60. Entry is posted to WHT GL account with total amount (basic TDS amount + 3% ECess).
But in certificate, there is no bifurcation for basic TDS amount and Cess amount. Cess field is comming blank in WHT certificate.
