hi thanks for ur help,
I tried the same formula but it not bring the correct result.
in formula field A, B and C, im using different calculation to fetch the data, and finally im applying it in D formula field to bring the final reult.
In A in fetchng the current yr quantity
B im fetching previous year quantity
C im fetching the rate
and final result D needs to fetch the result in the formula (A-B) * C.
when i written this formula it either fetched the value of A or B quantity not the right result.
