Dates in PMS Templates

Hi all,

When we assign template through Appcreate and write the validity & execution date from 01.04.2013 to 31.03.2014. All the functionalities are running fine.

Now, if suppose we change the validity date or execution date during Appcreate from 01.01.2014 to 31.12.2014 and assigning the template. We are not able to see our template in portal.

Please Advice.

Thanks & Regards
