We want to re-vamp the work centers and departments to where they make sense.  (this was first setup by others).  If we make these changes will the system automatically change everywhere?   I'm assuming on anything already printed, (work orders) that those would not update, correct?
 

Work Centers or Departments don't have GL information attach to them.
Classes do. SM-C.
 
General Ledger accounts have Departments. If you change a department you will have to change each GL Account that has that Dept.
 
 
 

I am trying to remember, we did it many, many years ago
I think what we did is to duplicate our GL accounts with a SQL script then
then use AM-H utility. It will transfer everything from account A to account B.
 
Ask Lynn, she will know.

Routing Departments CAN be associated with GL Departments.  They are different but there is a default setting (Evo Work Order Defaults, Processing II or DBA SD-Q) for "Link Work Center Dept to GL Dept".   If this is set to Y then the Absorbed Labor and Overhead postings made in  WO-F  Enter Labor or using Data Collection will post to the default GL Account and the Department based on the Work Center Department.  If it is set to N or Blank, then there is no correlation between the two.
