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, RWRK, RWRKQC 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.) 

RWRK and RWRKQC are used to move material directly to Rework Work center and rework Quality Control Work center. Would be used for RMA's ect... 

"SCRP" - 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.
