JMOP Not Calculating in PO, But Calculating in FB60

Hi Experts,

   I have an Issue regarding the condition type JMOP. We are using TAXINN and I have created a tax code for excise+vat. I have maintained the condition records for all excise conditions and vat and its posting perfectly in FB60. But when I am using the same tax code in PO, for condition type JMOP, the tax condition value is not calculating. But the ECess and SEcess is showing perfect value as calculated over JMOP. Screenshots attached.  Please guide me where I missed and what is the solution.

Thanks & Regards,
