TI-API: About COW (Change Order Window)

Part Number: TI-API

Tool/software:

Dears,

According to the Backlog API business guidebook:

d. API order change requirements

ii. Period for order changes or cancellations

Change Order Window (COW) is defined as the period during which changes or cancellations are no longer authorized for processing.

STD (Standard) COW: 30 days
Non-STD (Non-Standard) COW: 90 days

Additionally, in the backlog-order-management-api.yaml document, we can see:


responses: '200': description: Request processed successfully.

cancellationWindowWeeks: 5
rescheduleWindowWeeks: 5

My questions are:

1. Does Non-STD (Non-Standard) include Custom (CST) or is it the same as Custom (CST)?

2. How many days are cancellationWindowWeeks: 5 and rescheduleWindowWeeks: 5?

    Do they refer to the 30 days of STD (Standard) COW, or do they mean 7 days * 5 weeks = 35 days?

My users hope for precise information on the last allowable modification date. Therefore, I plan to calculate it using

    estimatedShipDate – COW days = LastAllowedModificationDate.

However, I am unsure whether the COW days should be based on the product category (STD: 30 days or Non-STD (or CST): 90 days)
or if it should be derived from cancellationWindowWeeks: 5 = ? days and rescheduleWindowWeeks: 5 = ? days. 
How many days are these exactly?

I appreciate your guidance on this matter.
