How to make Budget Control Exlcuded Line PO after Cancel Delivery Remainder

Dear Expert,

I used Budget Control in PO.

For The Example:


Item A : 20 Qty , Price : 1000, Line Amount : 20.000

In Budget Control for that FinDim, Encumbrance 20.000

Actual :

I’m only Receipt 10 and then Invoice, Encumbrance become 10.000

and then

I’m cancel qty Delivery remainder to make the PO close / Invoice status.

But when I check the Encumbrance in Budget Control still have 10.000 according the PO-123.

How to make the 10.000 in Encumbrance can be gone because the PO already close with Cancel Quantity Delivery Remainder
