Unless you are very new to Microsoft Dynamics NAV I am sure you know of the General Ledger Setup.
This is where we setup most General Ledger related settings such as Check G/L Account usage, the local Currency Unit (LCY) ,if VAT is in use or if we are using Unrealized Tax.
Many might not be aware that this also has a few hidden settings.
If you run table 98 General Ledger Setup from the Object designer you will see a few more fields then what the users sees in the standard page in your client.
A few that I have found very use full from time to time are:
| Field | What the helps say |
| Mark Cr. Memos as Corrections | Specifies whether to automatically mark a new credit memo as a corrective entry.
You can use the field if you need to post a corrective entry to a customer account.
If you place a check mark in this field when posting a corrective entry, the program will post a negative debit instead of a credit or a negative credit instead of a debit. The Debit Amount field (or Credit Amount field) on the relevant account will then include both the original entry and the corrective entry, which will have no effect on the debit (or credit) balance. |
| Amount Decima Places | Determines the number of decimal places the program will display (for example, on invoices and in reports) for amounts in $. The default setting, 2:2, specifies that amounts in $ will be shown with two decimal places. |
| Unit-Amount Decimal Places | Determines the number of decimal places the program will display (for example, on invoices and in reports) for sales and purchase prices for items, and for sales prices for resources in $. The default setting, 2:5, specifies that sales and purchase prices in $ will be shown with a minimum of two decimal places and a maximum of five decimal places. |
| Amount Rounding Precision | Specifies the size of the interval to be used when rounding amounts in $.
Amounts will be rounded to the nearest digit. |
| Unit-Amount Rounding Precision | Specifies the size of the interval to be used when rounding unit amounts (that is, item or resource prices per unit) in $.
Use this field to have the program round item prices on invoice lines when you sell to a customer or buy from a vendor in $. The program rounds the amount in the Unit Price field for customers and the Direct Unit Cost field for vendors, on the invoice line. Amounts will be rounded to the nearest digit. |
Especially the “Unit-Amount Rounding Precision” have come in great use many times where customers have special rounding requirements on their unit amounts (things like Item Costs, Prices with more).
One setting to rule them all.

Very usefull, indeed. Do you know of any other settings in the system, where with such check mark as “Mark Cr. Memos as Corrections” we can have entries posted with negative sign?
for example when running Adjust Cost, or the Adjuct Exchange Rate, or for Advance payments?
