Where do I start?
The level 2 classes for FI and CO is a good starting point into this area. These are AC010, AC040 and AC050. AC010 focuses purely on Financial Accounting (General Ledger, Accounts Payable, Accounts Receivable, Asset Accounting and some Cash Management). AC040 focuses purely on Management Accounting and examples are drawn from a Manufacturing Environment (Cost Centres, Internal Orders, Product Costing, Profitability Analysis and Profit Centres). AC050 is pure Management Accounting based in a Service Environment (Cost Centres, Internal Orders, Product Costing (for Services), Profitability Analysis.
What about the SAPFIN?
The SAPFIN course is a Level 1 introduction to Financials as a whole Financial and Management Accounting are only one component of this course so for many people this is not the best starting point. However it does provide a good overview to the whole of the Financials Area.
