An incoming payment has been generated and comprises the below structure.
The question....the $30 in open balance - where has this come from? How was it defined? And how was it selected for this incoming payment - as this field appears to be greyed out.
Details
Row 1 = invoice A for $200
Row 2 = Invoice B for $200
Payment on account $100
Total amount due $500 (total amount due comprises invoice A+B + Payment on account)
Open Balance $30
Thank in advance for your assistance
