VAT Surcharge Calculation wrong in Dealer Invoice

Dear All,

We have problem in VAT Surcharge Calculation in case of Dealer Invoice.

At the time of MIGO user has manually updated the Excise Amount and ticked the check box MRP Indicator and done the J1IEX also,

Now at the time of MIRO system is posting all amount correct except VAT Surcharge...

What could be the reason form the same?

Best Regards.
