Hello,

We have an scheduled job that goes every night to create customer invoices. 

Recently, warnings have started to appeared when the job are running. 

The warning text we get from the background job is Order: xxxxx ORA-20110:CustomerOrder:NILLED_ORDER_Invoiced orders may not be changed.

What we can see it apperas to create the Customer invoice anyways sometimes and sometimes the customer invoice don’t get created.

How and what can we do to avoid these warnings?
