Using Essbase variables as FDMEE Period POV

Hi Experts,

Here the matter:

1. I have a location to synchronize EPM applications (HFM and Planning or two Planning applications).
2. I create a batch to run this location (to be scheduled)
3. I create a Jython script to set Period POV, script to be launched as "Before Batch Script"

My question is: There a way to get the Essbase variables (&Mounth and &Year) and set them as a Period POV like dec-16, and run the location for this period POV.

For the event script, there is the "RUNTIMESUBVARS", but for a custom script there another way?

Could you help me please.
