Hi Mr. Rao,
Please check in T-Code OB90 that whether rounding digit 100 is assigned to the company code and currency which you are using or not?
Also in T-code OBQ1, select the appropriate condition type (Consult with FI Consultant) & double click, for which you want to maintain rounding value. Go to Group condition
Select round difference.
Indicator that controls whether rounding difference is settled for group
Conditions with a group key routine.
If the indicator is set, the system compares the condition value at Header level with the total of the condition values at item level. The difference is then added to the largest item. So it will rounded off to the nearest value of condition.
Regards,
Siddharth
