Got below error while invoicing the sales order

Error:

Sales order cannot be rearranged when included sales orders are tax regulated. Removed the regulation on the orders, rearrange and regulate the tax on the summary order dynamics.


Reason: 

"override calculate sales tax" check box on sales order -> Sell -> Tax -> Sales tax -> Adjustment tab.

Solution:

-> Go to Sales order > Sell(tab) > Tax > SalesTax
2. Click on the "Adjustment" tab
3. Click on the "Reset actual to calculated amounts" and close the form
4. Proceed to invoice and post invoice.
