I'm experiencing this with my credit card when it's being reflected on my UOB iBanking. 'Payment due on [DD-MM-YYYY] as $0.00' meaning they have received your payment for that statement month and you are not required to make any more payment till your next statement cycle.
I strongly believe is the same as DCP because Credit Cards, Line of Credit and Personal Loan are classified as unsecured facilities along with DCP, and it should be reflected the same format under UOB iBanking.
Hope this helps.
Appreciate the help!
