Deduction From and To Date in 2006 Absence Quota's

Hi Cronies,

In 2001 I have updated absence's From 24.11.2011 to 24.11.2011

In 2006 infotype I can see quota's but From Date and To Date is empty It should show from 24.11.2011 and to 24.11.2011 what would be the cause for this??

I checked all config steps still it is showing same..... In PT50 Transaction Code too Iam not able to see from and to date but i can see remaining entitlement's...
