SLC shape in promo effect
Hello dear experts!
Has a business task to build promotion forecast where promo has a shape similar to SLC item.
For example let have 2 promo in 2010 and 2011 years, both last 7 weeks:
The 1st starts at w13_2010 and ends till w19_2010
The 2nd starts at w17_2011 and ends till w23_2011
Need to receive same shape in 2012 starting from w16.
If I use base forecast I cant point to system where to start that event, but if I use promo forecast it just puts avarage for all promoted weeks
Is there any way to receive same shape for promo using only GA configuration?
