Introduction for WO Traveler Setup
The Work Order Traveler Setup module is used to define the details of the Production Work Order Traveler Setup for a product.   Certain work centers are “hard-coded” into the ManEx program. These are Material Staging, Finished Goods, MRB and Scrap. These work centers may not be modified by the user, or omitted from a Work Order Traveler Setup, because they are associated with special codes that are essential to our system.
 
For example:  "STAG"  is the first step so when a Work Order is created the material can go into Staging.  

"FGI"  when material is moved into finished goods a number of thing happen within the system, (1. Receiving into the inventory; 2. accounting transaction WIP to inventory, etc.)  

"SCRP"  and "MRB"  - if material is moved into scrap or MRB some GL transactions are associated with the move. 

They are the gateways to and from the Work Order Traveler Setup for WIP management.
