WTax in A/P invoice

Question

hello all,
i added an A/P Invoice (Services) to the system. after adding the A/P Invoice (Services) i make a A/P Credit Memo base on the AP Invoice that i created earlier.when i created the AP Credit Memo i included the WTax. after adding the Credit Memo the WTax Field in the AP invoice does not reflect the WTax that was deducted in the Credit Memo?  see Image http://i264.photobucket.com/albums/ii184/abing430/SAP/APCreditMemo.jpg
base on my screen shot my A/P Invoice WTax is 1,000. but since i made a credit memo w/c is WTax 500... this 500 wtax in A/P Invoice does not reflect. but upon checking on the ougoing payments (see screen shot) http://i264.photobucket.com/albums/ii184/abing430/SAP/Outgoing_wtax.jpg 500 Wtax reflect.
Now this is my problem, on the A/P invoice it says that 1,000 is wtax. how to display the 500 (the actual WTax)
Please help.
your Ideas is highly appreciated.
Thanks in advance.
FIDEL

Hi Fidel
Basically, it's correct.
When you create an AP Invoice, it shows the wtax as well as when you create an APCM w/ reference to AP.
In the AP, the 50,000 includes the wtax, the APCM, the 25000 includes also the wtax.
When you go back to the AP after applying a CM, you will notice that at the bottom part (Paid/Credit) the 25,000 is reflected already. And even after applying the CM, the wtax in the AP is still 1000. It's best practice and financial issue that it should not become 500 as what you expect.
But you noticed that in the Outgoing Payment, the wtax for the AP with applied CM, is reduced to 500.
Hope this helps,
