We're in the same position.  Our accounting has contacted Lynn, but we've received no resolution yet.

I have passed this conversation on to the accounting person having the problem. She will give me the answer as to how she does the process.
I checked my version of the screens SO-A (11/20/18) & SO-E (11/7/18). The accounting person and SO entry person is using SO-A (08/14/14). Accounting is using SO-E (11/7/18).
Today we billed the remaining part (serial controlled) on an order and the system went on ahead thru the release, print, post sequence automatically!! Plus it gave the new invoice number as the original one billed in Oct. for this last serial number????
Printed the one invoice number on two pages with the date for page 1 as 10/24/18 and page 2 for 01/07/19.
We are at wits end.
We do not assign serial numbers at time of SO-A. We religiously put them in at WO-I time. Work Orders are created for the line item quantity but then we cross it off and write 1 and initial and date the cross out. Thus, when we do the WO-I Enter Finished Production we do them one at a time and enter the serial number then.
Accounting says that S/N's are entered when releasing Sales Order.
Any assistance in solving this is greatly appreciated.
Thanks,
Liz

We are on EVO and she is using the T7SOE.RWN program.
Before the holiday break we updated to the 2018.2 & 2018.3 versions of EVO.
When we came back and billed the serial control parts for the first time is when the problem arose.
