Produmex Scan Custom Print Missing Parameter Values

Hello Boyum and Community,

I am triggering a Crystal Report print from a custom button in Produmex Scan, but I receive an Error: Missing Parameter Values.

My query is hardcoded for troubleshooting as shown below and includes the correct parameters for DocKey@ and ObjectId@. The Print Layout is the correct code, as is the name of the Printer setup in Scan.

Has anyone else ever run into this problem?

SELECT TOP 1
    'RLR20002' as "PrintLayout$",
    36 as "Print_DocKey@",
    15 as "Print_ObjectId@",
    'Soda PDF Desktop 14' as "PrintPrinter$",
    'Pack List is Printed'  "Message$", 'I' "MessageType$"
