Purchase Orders: Expected Ship Dates On Every Line

A purchase order used to carry one set of dates for the whole order, which forced buyers to keep partial-ship schedules in a spreadsheet on the side. Each PO line now has its own Expected Ship Date, and the PO Details tab is reworked around expected and actual milestones. Header and line dates are independent — setting the header does not push down to the lines.

Fill the lines three ways: type a date directly, copy the header date onto the selection, or calculate each line’s date from its lead time added to a base you pick at run time — issue date, confirmed date, or one you supply. Lines without a lead time come back in a Skipped list rather than failing the action, and every strategy resolves to a concrete date before it is saved, so a later rebuild does not recalculate to a date the buyer never agreed to. The header ship window is derived from the line dates, so an order with mixed dates reads as a range. PO dates now honor clear, set, and omit correctly for every date including Payment Due, and both the CSV export and import carry the Expected Ship Date columns.
