Hi Irfan,
Please use a PO which uses Tax E1 or U1 (having condition types JP1E, JP2E, JP3E... or JP1U, JP2U, JP3U) instead of Tax I1.
As per your tax procedure and design, it seems I series tax code (I1, I2, etc.) belong to inventorised (NVV account assignment) type tax code, where the tax amounts will always get inventorised and will get added to the material cost at the time of posting goods receipt.
For the desired scenario, where you want the material price to be excluding tax amounts, use a tax code which use condition types (e.g. JP1E, JP2E, JP3E... or JP1U, JP2U, JP3U) with other than NVV account assignment.
Let me know your results.
Regards,
SP
