May be a customization issue.

Do you have a screenshot or call stack of the error?

Namaste @Nhyiraba

System will allow to post even though currency code is blank in Sales invoice . It considers the invoice as local currency transaction as in below image

Seems its customization on currency Code field , Kindly verify the same .

If you feel it helped , please verify the answer

Agreed with previous comments. It must be some customisation. You can try to debug the same in Sandbox environment and fix the cause.

Thanks for the responses.

Got the customization response from a similar thread in the community, but was hoping there were other causes, since other companies on the system work fine.

We will debug on the Sandbox and revert.

You’re seeing: “The Currency does not exist. Identification fields and values: Code=''”
That means the system is trying to use a currency, but the code is blank. Purchases work, sales don’t—so something on the sales side is pointing to an empty or missing currency.
Try these quick fixes:

Check your company’s default currency

Open General Ledger Setup → look at LCY Code.

It should be something like GBP, USD, etc.

If it’s empty, fill it in—that alone often fixes this.

Look at the Sales Invoice header

Check Currency Code.

If you’re billing in your local currency, it’s normal for this field to be blank in the UI. That’s fine—as long as LCY Code (step 1) is set.

If it’s a foreign currency, pick the actual code (e.g., EUR) from the list.

Check the Customer card

Open the customer on the invoice and make sure Currency Code is either blank (use LCY) or a real code that exists.

If someone deleted or renamed that currency, posting will fail.

Make sure the currency exists (for non-LCY invoices)

Go to Currencies and confirm the code is there.

If you use exchange rates, make sure there’s at least one valid Exchange Rate.

If this has help you please mark it as verified

Technically if you don't have the currency then you will get the error message on the currency column it self.

Seems something is on top of base BC. Try uninstalling added extensions and see if it works.

The system doesn't throw an error at purchase Invoice and that’s exactly why this feels confusing.
Here’s why it happens:
> Purchase Invoices in Business Central don’t require a currency code if your vendor uses LCY — BC just assumes LCY automatically, even if the currency master record is missing.
> Sales Invoices, on the other hand, validate the currency more strictly. If the LCY Code is missing from General Ledger Setup or the corresponding Currency record is missing, it throws the error.
> So the difference is not in what you did, but in how BC treats Sales vs Purchase documents — Sales posting enforces LCY validation, while Purchase posting is more permissive.

This error usually occurs when the Currency Code on the Sales Invoice is blank, but the system expects a currency record to exist (even for local currency).
Steps to resolve:
> Open the Sales Invoice and check the Currency Code field on the header.
> If the field is blank, make sure that:
> The LCY (Local Currency) is defined in General Ledger Setup under LCY Code.
> The Currency table contains a record for your LCY (e.g., USD, AUD, INR).
> If using a foreign currency, verify that the currency exists in the Currencies list and has an active exchange rate in Currency Exchange Rates.
> Reopen or recreate the Sales Invoice if the error persists.
This ensures that the system finds a valid currency when posting.

Solution remains the same: make sure your LCY Code is filled in and exists as a currency record (and is properly set up with exchange rates). Once you do that, the error will stop.

Thanks
