Hi,
Yes the 14.169,10 EUR will be deducted from the WBS element. PO history tab will show only the history means all the transaction you have carried out.
You can see the document of 11.710,00 EUR without tax. because its Pur. document which is in base value.
IF you want to check the max value with taxes. then you should check under invoice tab. there click on taxes button. That will be deducted from WBS.
