Re: Header VAT and CST condition types.

Hi,

You can use NAVS condition or create a new condition type( copy from NAVS) and add in your MM pricing procedure which will bring all tax amounts to MM pricing procedure to NAVS condition type in your PO.

Refer for more for setting of NAVS condition type
