NullReferenceException When Adding an Order Header Misc Charge

dmmory · May 15, 2019, 7:11pm

We updated our Epicor 10 installation to version 10.2.300.12 a couple of weeks ago, and our CSRs are occasionally encountering errors like this in the Order Entry screen:

I checked the application server log, and it shows errors like this:

I was able to reproduce it on my test system by opening an order and adding an order header miscellaneous charge with a zero amount. If the order is on credit hold, I get a prompt like this:

If I answer yes, I get the error listed above.

I tried disabling all the method directives on the SalesOrder.Update and SalesOrder.MasterUpdate methods, I also ran the base order form to rule out any customization behaviors, but I still get this error.

If I either uncheck Ready To Process, or change the amount on the charge to something other than zero, it saves the changes without error.

Has anyone else encountered this?

I also noticed that before it allowed zero amounts in MSC charges. (our CSR’s were adding the line, so they do not forget, and then later edit with right value. If not, I had a BPM checking for zero amount msc charge, not allowing the save…

But

in 10.2 we noticed they do not allow this anymore. (not sure if it was your type of error, or a normal message from Epicor)
CSR’s are now adding the row with 1$ amount not to get an error and I changed my BPM to not allow save if = 1$…

Based your stack trace, its likely some custom coding with the BPM’s when it attempts to perform the MasterUpdate (Erp.Services.BO.SalesOrderSvc.MasterUpdate).

I disabled the directives, and I still get the error:

It’s the same error, it just the stack trace differs because no directives are firing.

I only get that error when adding new charges with zero amounts, not when I update existing ones. And even then, it only seems to happen if I get the credit hold prompt and answer yes.
