The cumulation classes 01 and 10 are active in standard SAP ..i.e i am able to tick or untick the fields of cumulation class 1 and 10 in t512w_O.
I am not able to tick or untick the feilds in any other cumulation class . I am planning to tick the cumulation class 11 , but this has been greyed out . I am unable to make the feild active .
Could anyone please help me to make any config changes to activate the feild in the cumulation class especially 11 .
