Tax amount going zero after adding a check prepayment

​@Manikanta Dhulipudi  This is because of setting “Disable Automatica Tax Calculation”. I have to keep it enabled in order to prevent this prepayment problem. But this is creating problem when we have multiple shipments from different warehouses.

Issue: The problem with the tax total being set to zero arises when adding a prepayment at the Sales Order (SO) level, preparing the second or subsequent invoice, and having multiple warehouses on the SO.

Cause: The underlying cause of both issues is the "Disable Automatic Tax Calculation" setting in Order Types.

Observation: When this setting is enabled (i.e., set to true), adding a prepayment works as expected, but it prevents the second invoice from calculating any tax, leaving it at zero. Conversely, if the setting is disabled (i.e., set to false), the tax values remain correct across two different invoices. However, in the case of a prepayment, the tax total for the SO is reset to zero.

Can you help me with some piece of codes that I can force in any upcoming invoices to add tax details in taxes tab on SO Invoice screen. Thanks
