Strange Issue in Oracle scheduling.

Yearly schedule is executing on monthly basis.

Yearly schedule is exepected to run at start of the year and policy is specified in script as 

varaible defined 1st....

NB_ORA_POLICY=policyname

main clause is (vaule of variable assgined in main clause.)

RUN {
ALLOCATE CHANNEL ch00 TYPE 'SBT_TAPE';
ALLOCATE CHANNEL ch01 TYPE 'SBT_TAPE';
ALLOCATE CHANNEL ch02 TYPE 'SBT_TAPE';
ALLOCATE CHANNEL ch03 TYPE 'SBT_TAPE';
   send 'NB_ORA_POLICY=${NB_ORA_POLICY}';

Yearly and monthly policies are different.

I have taken a llok at http://www.symantec.com/business/support/index?page=content&id=TECH31742 but dont find it related to me.
