Last year the curriculum development team decided to change several of our CO courses to a new structure. AC405 was replaced by 2 seperate classes, AC410 Cost Center Accounting, and AC415 Internal Orders. They did the same thing with AC505 and comverted it to AC506 and AC507. The North America FICO team felt the combined format better met our students needs.
We made the decision to go back to the previous format. The problem is, we could not use the old course codes. This has caused much confusion about which classes to enroll. The North America region now has class WNA505. It replaces AC506, and AC507. WNA505 is a five day course using the original format and subject matter. It covers product cost planning, extended functions in product costing, and other topics. We made a similar change with WNA405. It is a five day class as well, replacing AC410 and AC415. It covers the Cost Center Functionality and Internal Order information.
The class materials are available for the WNA versions and the courses in the schedule should reflect this format in the North America Scheule. The classes scheduled past May, 2013 should reflect the WNA numbers. If you search other regions or the Global Library you will see the split AC course format.
