The error that's generated during the process is misleading. I think there's something else going on which is preventing the process from completing. Here's the general error info:
Processing the Document "DocumentNumber" in Sage failed
Current Company
Company Data path: \\servername\SAGE\SAGE2018ADV\MAS90\MAS_ABS\
Current Module: Sales Order
Fatal Error creating S/O Sales Order in Sage.
12 - Error #12: File Does Not exist (or already exists) File: JC_Options
<NewObject Error: 200>
The Job Cost module isn't installed, I even went as far as installing it with the 45 day trial period option. After installing Job Cost the developer tried the testing process once more and the error still occurred.
The developer has gone ahead and installed an NFR copy of Sage 2018 on his own machine, without job cost, and he's been able to import from Quoteworks to Sales Order.
I have ensured that the enable external access option is turned on in the Sage company maintenance screens.
Does anyone have any ideas on how to resolve this?
