Ya Okie Sander, As guided I will do that. But this is fairly strange when I remove the customer exit & replace it with a manual input variable(on Calyear) , everything works good to me. Only concern is, It would be pretty difficult to explain to client why this is happening & then ask them to open OSS.
Apart from the LOV(list of values) in 'Select report Filter', strangely when I used Customer Exit , & remove the Employee(Drill Out from the report), report collapse stating no applicable data found. However when I used manual input variable , then when I drill our Employee column behave normal by aggregation key figures next to employee column .
No explanation why this happening.
Kind Regards,
Fox
