CLONE 2020R4 - SO Processing time forecast adjustments are not skipping Sunday 0 forecasts

Example store 04012

Order 3730208 for , 8/26, has low forecasts for all of the items on the processing time pilot. Their forecasts are quite consistent and they receive daily trucks, but their forecasts yesterday were about 2/3 of their "normal" forecasts for all of these items

it appears that Sunday is being included as a forecast day instead of being "skipped

Sunday 0 forecasts are not being 'skipped' when forecast window is adjusted due to the "processing time" feature.

Note: Skipping Sundays was implemented under: CFAMX-9245
If my memory is still working, I did test and demo this, and it all worked

Problem?!?

• processing time = 48 hours
• order placed on Thursday, for Delivery on Friday, Cover Until Saturday
• in this instance, the forecast that we should be using is:
  • Start = Saturday
  • End = Tuesday
  • Where do these days come from?
    • Start = Order day + 48 = Thursday + 48 = Saturday
    • End = Cover Until + 48 + 24 (if the 48 spans Sunday) = Saturday + 48 = Monday, but Sunday is in the range, so add another 24 = Tuesday
• But we are not accounting for Sunday correctly
• So we are giving Monday as the End
• Resulting in the forecast range being Saturday - Monday
  • which really only includes the forecast for Saturday
• Stores trusted the suggested order, and are now running out of product

Example from Staging:

• Order placed Thursday, for Delivery Friday, Cover Until Saturday
• Processing time = 48 hours
• Forecast range should be Sat Aug 29 - Tues Sep 01
• What we see:
