After balancing among current PLANSALE & PLANPVC, I found the impact on 258RB. I would propose to extend the
current campaign 258RB until Oct 21, 2015 and transition to 261RZ on Oct 22, 2015. (see more detail in below table)
It is very appreciate if we can get 258RB more than 120 mt during 14-21 Oct 2015. (let say plus 7-8%)
