Hello All,

Please answer the following questions. This is a big customer.

1. When and how does the promise date, requested scheduled date get updated in Order Header and Order Lines?
2. Is that value editable or updatable using Post transformation Rules or Order Management Extensions.
3. Which is the correct place to code the logic for calculating the promise date and requested scheduled ship date? The customer would like to use som business rules to calculate the Promise date and Requested Scheduled Ship date.

For example, Promise date = Max (initial scheduled ship date from GOP+ Intransit LT, Scheduled ship date form GOP+Post processing lead time)+ Fixed Lead time
