i use TAXINJ procedure all required settings done.
here i make PO ( but at the time of making PO , as a purchaser not knowing the exact condition,he takes condition randomly).Then do MIGO. At the time of MIRO, i know the exact rates.(But as per PO , my modvat is coming 15000INR). but as i know the exact condition , i want it 10000INR ). How i adjust this amount difference 15000 - 10000 = 5000, at the time of MIRO.
