Hi,
I believe, you should have basic Accounting knowledge to understand any ERP system.
This would help you to learn new system in much simpler & faster way.
Typically, you should have clear idea about financial terms like Chart of Accounts, Credit / Debit, Profit & Loss, Balance Sheet, Taxations, Basic Accounting (Like Invoicing, Bank, FA, Cash Expenses) etc.
Once you are aware about this, it would be really easy for your to configure the NAV ERP system.
Basically, Finance is the most important module in any ERP system, as all the modules are moreover integrated with finance and hence need to be very careful about all the required set-ups like Accounting Period, General Ledger Setups, Posting Setups (G/L, Vendor, Customer, Inventory, FA, Bank etc.) , Currencies, Taxation related setups etc. to be configured in the system.
Apart from Financial setups, you have few important screens to work with, as follow.
1. General Journal
2. Payment Journal
3. Bank Reconciliation
4. VAT Settlement (if applicable)
5. Invoicing & Credit Memo (Purchase & Sales)
6. Fixed Assets (Depreciation)
7. Analysis by dimensions & Account Schedules (for reporting)
8. Periodic jobs like Adjust Cost Item Entries, Post Inventory to G/L etc. (as applicable)
Once you are through with the above, you can go ahead and learn advance finance modules like Budgeting, Intercompany accounting, XBRL reporting, Cost Accounting, Cash Flow, Inventory Costing etc.
You can go through various videos on YouTube to get more details. Also, refer following link on MSDN to get the complete understanding of NAV financials.
