I need to derive “Target” line based on the actual data. The data is displayed in quarters and the first quarter value is considered as the base value for Target from there on for each quarter there should be 2.5% decrease(in a year 10% decrease).
For example if the Q1 Actual data is 10159 then the start for “Target” is 10159 for Q2 the Target should be 9897, Q3-9638, and Q4-9377
I hope the requirement is clear and makes sense. Thank you,
