This field in the Purchasing and Receiving window has three available values: Blank, A, and S. The purpose of this field is to define what the Ship Date field means. If you want the vendor to ship merchandise to arrive by a certain date, set to A. If you want the vendor to hold shipping until a certain date is reached, select S. For example, you create a large seasonal purchase order in the fall, but do not want to take delivery until early in the spring, in that case you would populate the Ship Date with the date you want to have the vendor to start shipping.
A – You want the vendor to ship the merchandise to arrive by the Ship Date.
S – You want the vendor to hold the merchandise and to start shipping on the Ship Date.
Blank – No ship date is defined for the purchase order.
