Customer Credit Limit/Blocking

Hello,

We are using IFS Applications 10.

We wish for the Credit Block functionality (via "Credit Limit" value on Customer:Credit Info tab) to consider only our Customer AR Balance (Unpaid Invoices) and not the sum of Customer's AR Balance + Total Value of Open Orders (i.e., Backlog Orders) when performing credit checks during Customer Order processing.

Is this possible?   Thanks for the help!
