Start Dates for Planned Builds can be shown on the Adjustments list as a new column.
Planned Builds defer changes to inventory until they are Completed and instead change Allocated so you can see what you need to buy or have available as you do for Orders.
Like the Ship Date on Orders, the Start Date on Planned Builds estimates when you will need the components. With reliable entries you can work from Adjustments list.
To see Ship Dates, go to Adjustments and click Add(+) to show Status and Start Date.
