Blank is Better (For LCY)

If your Local Currency (LCY) is already configured in General Ledger Setup, don't add it again to the Currencies page.

Business Central already recognizes your local currency through the General Ledger Setup, so creating it as a currency record is unnecessary and can lead to confusion or setup issues.

What You Should Do Instead

For transactions in your local currency:

• ✅ Ensure your Local Currency is defined in General Ledger Setup.

• ✅ Leave the Currency Code field blank on sales, purchase, and journal transactions.

• ✅ Let Business Central automatically treat those transactions as LCY.

Only use the Currency Code field when you're working with a foreign currency such as USD, EUR, GBP, or another non-local currency.

Sometimes the best setup is the simplest one. Understanding how Business Central handles your local currency can save time, reduce errors, and make your finance processes more consistent.
