Reporting Requirement based on Key Date

Hello Team,

My Requirement is , User is giving a key date & I have to find the Fiscal year corresponding the date keyed in , calculating all the fiscal periods last date & then restricting a key figure with every fiscal year period last date.

To achieve this , I have created a 1 Manual input variable on 0Calday & then 12 Customer exit variables each for last date of each fiscal year period.

Now my issue is as 0CalDay is not mapped from anything from Source.

So how should I prompt user to key in date .

Please suggest .

Thanks in advance.

Regards,

Pankaj
