Invoice value deuction from WBS?

Hi Experts,

I have a doubt regarding Invoice budget deduction from WBS, below you can see the PO history tab in which value is 11.710,00 EUR whereas inside the Invoice (in second screenshot) you can see value 14.169,10 EUR (with taxes) -

I want to just confirm whether value (with taxes) 14.169,10 EUR would be deducted from WBS or the value (without taxes) 11.710,00 EUR .

And if max value with taxes would be deducted from main budget of WBS, then why in PO history tab we always see the base value according to PO not the value with taxes. (please refer attachment for clear pictures)

Thanking you all in advance.

Regards,
