Field help (WIPSTA2) 

This field displays as a 3-character code, the type of order that is currently work in progress plus the current status of the order.

The first two characters = the order type; the third character (S (Suggested), P (Planned) or F (Firm)) = the status of the order. For example, POP means ‘Purchase Order Planned’, SOF means ‘Sales Order Firm’.

'In progress' events display a greater than ('>') symbol after the code; Intersite events display '~' after the code. For example, a firm purchase order (POF) that has been partially received is shown as: 'POF>'.
