SD Billing Proc to effectively delay the VAT liability till payment is made

Question

Dear All,
Need your valuable advice to set up below in SAP.
Billing Process to effectively delay the VAT liability till payment is made
This is a kind of biling process, where we can send an application to the customer for payment,
then customer pay what they think is due for work (settlement) to date, then vendor raises invoice.
This effectively delays the VAT liability till payment is made,
where as creating invoice document, the VAT is due based on invoice date not payment.
Thank you in advance.

You cannot use string literal of more than 4000 characters in an Oracle SQL statement. I'm not going to count that string you so rudely posted but I presume it is longer than that figure. You'll need to use a variable instead.
declare
    c clob := '<your vast XML doc here>';
begin
    update PRVDR_ENRLMNT_AGREEMENT B set b.terms= c
    where ....
{code}
