Hi Shiva,
The earnings may not be coming because of the payslip design.
The wage types coming under Earnings say from IT0008 (Basic Pay etc) and IT0015 (Additional payments) will need to be maintained with evaluation class (check Table V_512W_D)
Now we have the PE51, where we have 'Windows' 'W1' (double click on it) and select '01' for earnings and add the earnings wage types.
similarly for 'W2' for deductions window.
also, we have 'cumulation IDs' where the Earnings will be added to the respective cumulation IDs.
Are the wage types are reflecting in 'RT' table? Please check the payroll results.
Thanks,
Madhav.
