Abhilash,
I have been working on this but I can't get the date I need. I have inserted a screen shot for you.
The date I need to get is "Previous Actual Due By Date". This date is actual date on a field and is second after last record.
I have a "presumed " date calculated, which is called "Calculated Due by Date" this date ideally should match with "Previous Actual Due by Date". If it matches, my formula shows " Normal", if it doesnt , the formula shows "Abnormal". Currenlty this formula isn't displaying correct information because my "Previous Actual Due By Date" field isn't getting the right date .
The current calculation I use is:
if Count ({Due By Date/Time}, {PPM ID})>1 then next({Due By Date}) which is obviously wrong calculation.
I hope you can bring me on correct path .
