How to prevent tax type adjustment against Invoices with no taxes?

Hi,

Normal Scenario:-

I have an invoice A having Revenue line total $1000 and Taxes total $20. I performed Invoice accounting correctly.

Now I have made an adjustment against the Invoice A with TYPE as 'Tax' for $10. I performed Adjustment accounting and I could not find issues. All goes well.

Invoice

Rec 1020 Dr

Rev 1000 Cr

Tax 20 Cr

Adjustment

Adj 10 Dr

Rec 10 Cr

Failed Scenario:-

I have an invoice B having Revenue line total $1020 but no Taxes. I performed Invoice accounting correctly.

Now I have made an adjustment against the Invoice B with TYPE as 'Tax' for $10. I performed Adjustment accounting and it failed.
