How do I get the active field of DateEditor in JSpinner?

Question

Hi Everybody,
I have a JSpinner which uses a DateEditor and displayes the date in "dd/MM/yyyy" format in it. I have over ridden the default behaviour of Up and Down arrow button components of it as per my requirements. Now I want to extend the functionality to change the value of the date on the basis of what is the highlighted field.
ie if the month is highlighted then the day and year need to
remain the same but month should increase.and if day is higlited it
shud follow the normal pattern and if year is highlighted the year should
move forward keeping the month and date same (no doubt after 12 months increment it is supposed to go to next year). Here is my code:

Simmi,
    you need to check in SE11(data dictionary) with the specified tachnical names.
comming to selective deletion...
divide the data into segments based on the organizational values.
take the material group. check with any consultant. ask simple qustion how many material group we have?
take the case 5 mat1, mat2, mat3, mat4, mat5. Delete the values based on that. Menas that... entire infocube defined into 5 segments.
Before deleting make sure u have taken correct charecterstic. if you can give us the scenario we can let you know how can we delete the data with out effecting existing business process.
alll the best.
