one thing i want to ask here..
after i tried i get solution what i want but there is another problem that
here i apply condition on P No that whatever the value before " -1 " it should minus "-1" and paste value in P_No_1
if(Right([P No.],2)='-1',SubField( [P No.],'-',1)) as P_No_1
but here is incremental load thing apply on P NO that when polices increases with same P NO then increment apply in data e.g. "P/03/Me/2018/00003-1" when another polices then this will be P/03/Me/2018/00003-2 when 3rd time assigen then this will be P/03/Me/2018/00003-3
so here i want whatever the number after dash " - " this would be minus and before " - " sign whole value will paste in P_No_1 column
how i do that..
