Default Customer Address Relationship for Forecast Consumption by Customer in R3483

Hi,

In R3483 processing option in Forecasting tab there is option to set Ship to or sold to in Default Customer Address Relationship for Forecast Consumption by Customer field. What is the implication of setting this? And also what is the implication of setting value in P3406

Example:

on 26/8/2022 Forecast is for 1000

on 26/8/2022 sales order sold to is 900

on 26/8/2022 ship to order is 800

If PO value is set to sold to will system ignores the 800 in forecast consumption by customer calculation?
