Hi,
I can see from the PO taxes screenshot, that you have maintained 'Zero' percentages for all excise condition types. Problem seems to be in the 'Zero' percentage condition records. As you have maintained 'Zero' percentages for 'Set Off' conditions for tax code '70', system is not considering excise duty amounts for calculating VAT in MIRO. As i explained in my previous post, for tax code '70' maintain the condition records as below,
i) BED - JMOP - 0%
ii) AED - JAOP - 0%
iii) AED Set off - JAX1 - 100%
iv) BED Set off - JMX1 - 100%
v) Ecess - JEC1 - 2%
vi) SEcess - JSEP - 1%
vii) Ecess Set off - JEX1 - 100%
viii) SEcess Set off - JHX1 - 100%
ix) VAT - JVRD - 5%
Also check whether you have 'GR based invoice verification' activated in PO. Test the scenario again by creating new PO, GR and MIRO.
