Will an invoice hard limit flag stop a credit invoice from generating?

There was a fringe adjustment done on a fully expended and invoiced project.  Now the credit will not generate an invoice.  Will the invoice hard limit flag stop a credit from invoicing?  I'm not seeing a date issue that would stop the invoice generation, but didn't expect that a credit would be stopped by the invoice hard limit.  Could that be the culprit? 

Thank you for any advice
