We have an requirement. I have a table having Some fields.Two fields are of Date fields Date1 & Date2. In respect of Date1 field there is a Value1 field. We need to derive the Value2 with respect to date2.
Value2 is depend on 3 fields Customer, Date1 and Value1.
Example in Excel Sheet::
For C1 ,Date1 is 01/01/2016 and Value is 100.Therefore for Date2 we need to derive the value2.
Logic is that if for Same Customer Date1 <=Date2 then Value1 will be the value2.
For Column 1 Value of Value2 will be 100 because Date1=Date2.
Other case Column2 ::Date1 > Date2 ,In this case we will see the upper value of Date1 if this Date <= Date2 then Value of Value1 for that will be the Value of Value2.
For Column2 Value2 will be 100.
Same for column3 Value2 will be 100 because Date1> date2.
So we are always assuming the value of value2 ,according to date2 where Date1<=Date2.
If not then we assuming previous value. If the previous Date is also large then we will check upper of the previous value.
