You're getting the “transactions on voucher do not balance” error because you're manually modifying accounting-related amounts (like InvoiceJour.InvoiceAmount) without ensuring that all dependent transactions and ledger entries (especially customer and revenue accounts) are updated accordingly.

❌ Problem Summary:

You tried to apply a custom discount by reducing the InvoiceJour.InvoiceAmount to 720.00 from the original 800.00 — but the ledger entries (e.g., revenue and receivable accounts) still reflect the original 800.00 revenue, which causes the voucher to go out of balance by -80.00.

✅ Correct and Supported Way to Apply Custom Discounts

To deduct a discount in Sales Order Invoice posting, do not directly update InvoiceJour. Instead, use one of the supported approaches below.

✅ Solution Option 1: Use a Custom Miscellaneous Charges Line

This is the recommended and safe method.

➤ Steps:

Go to Sales Order > Sales Order Lines > Line > Charges.
Add a negative miscellaneous charge (e.g., -80.00) to reduce the total.
- Ensure it posts to a discount GL account (e.g., 604000 – Discounts Given).
Recalculate totals.
Post the invoice.

This way:

Sales amount is still 800.00
Charge reduces it to 720.00
All ledger postings are auto-balanced
InvoiceJour will reflect 720.00 net

✅ Solution Option 2: Update `LineAmount` via `SalesParmLine`, Not `InvoiceJour`

If you still want to manipulate amounts programmatically (not recommended), do it at the line level using SalesParmLine before invoice posting.

➤ Example:

x++

SalesParmLine parmLine;

select forUpdate parmLine where parmLine.SalesId == '006110' && parmLine.RecId == yourRecId;

parmLine.LineAmount = 720.00;

parmLine.setInventNow(); // Ensures packing/slip qty recalculation

parmLine.doUpdate();

Then let the system post the invoice. Do not touch InvoiceJour.InvoiceAmount directly – it’s calculated automatically from SalesParmLines.

🛑 What You Must Avoid:

Never directly update InvoiceJour.InvoiceAmount – this breaks financial posting logic.
Don't bypass SalesFormLetter_Invoice processing.
Don't manually try to balance ledger entries unless you're writing a full custom posting routine, which is high risk and error-prone.

✅ Recommendation:

Use Option 1 (Misc Charges) unless you have a business rule that strictly requires custom code – it’s robust, safe, and aligns with D365FO posting logic.

If your business logic requires programmatic application of discounts, share more details (e.g., fixed per customer, conditional rules), and I can guide you through a correct coding extension using PriceDisc, SalesLine, or Charges.
Let me know if you'd like sample code for adding the negative charge automatically during invoicing.
