EPMMemberProperty not refreshing the Property value

Dear BPC Friends,

I am creating a BUDGET input template in EPM 10NW and I have created a flag (i.e property) in Category dimension. This flag/property is BUDGET_YEAR  and the value of this will be year i.e 2014,2015.

I am using this property in the template  to define time columns range  i.e 2015.Jan.---2015 .Dec. When I pull this value using EPMMemberProperty it only pull the value in template for the first time. After this if I change the value in Category dimension, it does not get refreshed/changed in template. I have done following

1. 1-      Refreshed Metadata for current connection
2. 2-      Refreshed the report many time
3. 3-      Logout and log in back
4. 4-      Category dimension  has been processed well as the status  shows green signal.

Kindly advice as what could be the reason for this problem.

Thanks,

Rahul
